DataGridView: How Can I Update Data In A DataGridView?
Jan 11, 2007
Hi guys,
Im having some issues understanding how to manipulate the data that is in my DataGridView
The View is created by calling a stored procedure from VB code and works on two tables:
people
pswds
The columns required from Table people are (personid, userid and sort).
The columns required from Table pswds are (comment and activeuser).
Table people is parent table while pswds is the child table.
The Relationship works between both tables using primary keys from both tables: which is called personid in both.
The link below shows the Relationship Diagram for the Two tables:

The code for the Stored procedure can be found at the following Link:
http://cale.csd.anglia.ac.uk/~csd03ib/images/StoredProcedure.bmp
Now the DataGridView returned by the Stored procedure produces the following output found at this link:
http://cale.csd.anglia.ac.uk/~csd03ib/images/DataGridView.bmp
Of course there are many more results returned for this DataGridView but i have only shown a few of them. What i really need to know is:
Can this view be made to be editable?
I need to be able to update the both the Active user Check box and the Comment Columns from this view
I hope someone can help
Thx Flakky
I am sorry for asking such a broad question, but I have been working on this and from what I can gather it can be done. My problem is that much of it has gone right over my head and I am getting more confused the more I read... I'm really, really confused...
Basically, I have a dataGridView that is populated with a number of fields from Table1 (ID, NameID, Status, Phone, Notes). This works fine, BUT I would like to access Table2 and have, where ID in Table2 = NameID in Table1, it load the First Name & Last Name into the dataGridView. I am able to load the information from Table 2 like so: SELECT NameFirst + ' ' + NameLast from Table2", but I can't get both Tables to work correctly.
I would like the dataGridView to be layed out like this:
ID NameID Name (NameFirst + NameLast) Status Phone Notes
I can't for the life of me understand or get this to work (Or for that matter even understand what I am trying to do...
Also, I am using Access 2007.
I would greatly appreciate some help, and possibly some explanation in laymans terms so that I might be able to understand this. I have read a lot about this, but for whatever reason it is just soooooo over my head that I can't follow it whatsoever.
// create and open the connection OleDbConnection conn = new OleDbConnection(conString); OleDbCommand command = new OleDbCommand(); command = conn.CreateCommand();
// create the DataSet DataSet ds = new DataSet();
// run the query command.CommandText = "SELECT ID AS [#], NameID AS [Name], Status AS [Status], Phone AS [Phone], Notes AS [Notes] FROM Table1 WHERE ID = " + textBox13.Text + ";"; OleDbDataAdapter adapter = new OleDbDataAdapter(); adapter = new OleDbDataAdapter(command); adapter.Fill(ds);
// close the connection conn.Close();
bindingSource1.DataSource = ds.Tables[0];
dataGridView1.DataSource = bindingSource1;
// set the size of the dataGridView Columns this.dataGridView1.Columns[0].Width = 10; this.dataGridView1.Columns[1].Width = 100; this.dataGridView1.Columns[2].Width = 100; this.dataGridView1.Columns[3].Width = 100; this.dataGridView1.Columns[4].Width = 176;
Hi. i created a small database with a table to store two numbers and the sum. num1,num2 and sum column. In sql i used the computed columns specification to assign sum as num1+num2.
running the database, everything works fine. i input the numbers and the sum is auto calculated.
i try to do same thing by bring the table in a vb 2008 form using a datagrid view. when i run the application i can just enter the two values(num1 and num2) in the datagrid but the sum is not calculated despite pressing enter or tab and also the data entered is not saved.
Hello, I have a datagridview setup right now to display data from one table in my database. However, I am going to need it to pull certain columns from certain tables and put them all into one datagrid. The three tables are demographics, financial, and procedures. Can someone give me an example on how I'd go about doing this? I'm using vb.net.
The procedures table is a list of options that will be displayed in a combo box, depending on the option selected, other cells in the datagrid will be filled with certain data, this data is in the procedures table as well. All of this data will be alongside a customer id located in the demographics table, and will all be recorded into the financial table.
I have made a couple of queries I want to use into a Visual studio project, Now is my problem:
All my queries have different statements. I believe the best is to show the results in a Datagridview
How to view them there? I know how to do it... but I have got about 30 queries
Here is my code so far:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ComboBox1.DataSource = MyDB_DevDataSet.DataSetName. Dim connectionString As String = "Data Source=myDBmySRV;Initial Catalog=Teknotrans_dev;Integrated Security=True" Dim sql As String = "SELECT * FROM CompanyMain"
I am currently using VC++/Cli 2005. In a project, I'm using a DataGridView control to show records from a SQL Express 2005 table. Instead of updating a specific item directly within DataGridView control, I would like to open a new form and allow user to update selected record/item within that form. The reason to update this way is conditionned by the fact that I have 3 levels of detail as following:
Level 0 Level 1 Level 2
1:N 1:N Furniture --> Component --> Component
You all understand that update form of Level1 will/must include, as Level0 do, another DataGridView control to display/detail all related items issued from next level. This explains why I can't allow user to update Level 1 directly from DataGridView control.
I've searched in MSDN and even bought a few books on subject but unfortunately I found nothing on how to do it this way. All articles on DataGridView control were only showing how to update record directly from control.
My approach, I think, would be to transmit to my level1 updating form, as a single parameter, the selected DataRow object (or a brand new one if currently adding) issued from DataGridView and let user update it's content. When User finally leaves level0 update form, then I presume that DataGridView corresponding table would be automatically updated according to DataGridView's content.
What would be the proper way to do it? I would certainly appreciate to hear you view on this.
Also, what can I do if I want to refresh DataGridView's content when coming back from update form. Is it done automatically? I would certainly be sure that it reflects the reality, not only when I update it myself but also especially when other users could concurrently update same records?
I run the following statement and it will not update beyond 7 million plus rows and I have about 38 million to complete. I keep checking updated row counts and after 1/2 day it's still the same so I know something is wrong because it was rolling through no problem when I initiated it. I need to complete ASAP so it's adding to my frustration. The 'Acct_Num_CH' field is an encrypted field (fyi).
SET rowcount 10000 UPDATE [dbo].[CC_Info_T] SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v' WHERE [Acct_Num_CH] IS NOT NULL WHILE @@ROWCOUNT > 0 BEGIN SET rowcount 10000 UPDATE [dbo].[CC_Info_T] SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v' WHERE [Acct_Num_CH] IS NOT NULL END SET rowcount 0
When I enter over 4000 chars in any ntext field in my SQL Server 2005 database (directly in the database and through the application) I get an error saying that the data could not be updated because string or binary data would be truncated.Has anyone ever seen this? I cannot figure out what is causing it, ntext should be able to hold a lot more data that this...
I want to make data changes in read_only database , that's why i must set database read_write. While database is at read_write mode, i want to be sure that no one makes change in database.
For this aim, i write the code below, but i suspect that after setting the database read_write, till the setting database single_user ,is it possible get DML script from another user. Is the code below enough for this operation. Or is there another way?
Reminding: Read_only database can not be set single_user mode. That's why, first you must set database read_write.
The code;
use master alter database xxx set read_write with rollback immediate alter database xxx set single_user with rollback immediate
use xxx update tablexxx set columnxxx=yyy use master alter database xxx set read_only with rollback immediate alter database xxx set multi_user with rollback immediate
Hi,First post so apologies if this sounds a bit confusing!!I'm trying to run the following update. On a weekly basis i want toinsert all the active users ids from a users table into a timesheetstable along with the last day of the week and a submitted flag set to0. I plan then on creating a schduled job so the script runs weekly.The 3 queries i plan to use are below.Insert statement:INSERT INTO TBL_TIMESHEETS (TBL_TIMESHEETS.USER_ID,TBL_TIMESHEETS.WEEK_ENDING, TBL_TIMESHEETS.IS_SUBMITTED)VALUES ('user ids', 'week end date', '0')Get User Ids:SELECT TBL_USERS.USER_ID from TBL_USERS where TBL_USERS.IS_ACTIVE = '1'Get last date of the weekSELECT DATEADD(wk, DATEDIFF(wk,0,getdate()), 6)I'm having trouble combing them as i'm pretty new to this. Is the bestapproach to use a cursor?If you need anymore info let me know. Thanks in advance.
i am really in need of help. i have a text file consiting of some data.i want to update my database from that text file periodically say 12 hours.the text file is being updated by another server program in every 12 hours can any one help me in this case? i am lost for this scenario?? help me please.....
Msg 209, Level 16, State 1, Line 8 Ambiguous column name 'PartNrFabrikant'. Msg 209, Level 16, State 1, Line 8 Ambiguous column name 'omschrijving'. Msg 209, Level 16, State 1, Line 8 Ambiguous column name 'verkoopprijs'. Msg 116, Level 16, State 1, Line 13
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
finding one set of data within another set of data for update,so if within column 1 it finds the results from another select on another table, it updates a different column with the result.
Example
SELECT Title from H..Import_Table returns 'PRN - Concord' 'PRN - San Jose' 'SLP - PRN - San Jose' 'San Jose - PT - PRN'
I have created a table in a database for a football that I want to update as the season progresses. Is there any way I can add the new data to the old data in my columns through SQL rather than searching for the old data, doing the maths in my head and doing a simple update query? I know it doesn't save much extra time but I can get awful lazy when it comes to extra maths!
Example would be:
Player Minutes Adam 287
Adam has played 287 minutes prior to the most recent match in which he played 67 more. I would like to know if its possible to do an update where I can just simply add 67 onto the existing numbers with one query rather than find Adam's minutes, use a calculator, do a table update.
My goal is to split the full contact name into first and last as well. Because that is what is in the database and I want to keep it consistent for the few thousand records missing it. Do I update this using a stored Procedure? How would it be formed? CREATE PROCEDURE dbo.ap_Insert_FirstLastName_WhereNull SELECT * FROM Booth_Visitors_Data WHERE First_Name IS NULL And Last_Name Is NULL And Contact_Name IS NOT NULLORDER BY Contact_Name Desc Update Booth_Visitors_Data Set ?? Or is this impossible with a stored procedure? SHould I wirte a .aspx page to do it? Or can I do it all in code-behind??Protected Sub btnUpdate_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpdate.Click Dim con As New SqlClient.SqlConnection con.ConnectionString = "Data Source=10.10.10.10;Initial Catalog=Leads;Persist Security Info=True;User ID=xxxxx;Password=xxxxx"Dim myCommand As New SqlClient.SqlCommand myCommand.CommandText = "SELECT * FROM(Booth_Visitors_Data) WHERE(First_Name Is NULL And Last_Name Is NULL And Contact_Name Is Not NULL) ORDER BY Contact_Name Desc" myCommand.BeginExecuteReader() myCommand.Connection = con con.Open() con.Close() End Sub If I can do it in code-behind, how does it look in modern .net code as opposed to the old classic asp way?

I am a SQL Server Express and VS 2005 rookie. I currently have a form with a datagrid on it, mapped to a binding source with everything basically done for me using a wizard. I want it so that the user can enter data into the grid, and the data is stored in the database. However, everytime i click save, it doesn't actually save the data, so that everytime you execute the application in debug again, the data is gone. I have the End Edit and Update statements correct. What is wrong!
Hello all,I'm new in this newsgroup and I apologise if my question has already done.Let me knwo if FAQ is avaible somewhere.I use msSQL server to manage data for a B2B portal.Orginal data comes from as400 db2.I need to update msSQL data from db2 source.I used MetaDataService executed by SQL server Agent, but dosn't work asexcepted 'cause I need to delete all row in a table and then copy all newrows, this works fine but what happen if an user is quering data while sqlagent starts?I need to make data update very often so I need other solution.The update procedure must follow these rules:1- check diffrents between a table in DB2(source) and the same table onmsSQL server2- update my msSQL table if some diffrents was found.I'm a beginner with msSQL server, any advices are welcomed, I need a startinpoint.please help.thank you allkindly regardsAlberto
I have been trying to think of a solution to a problem i have and still not sure how to go about it.
I have a database filled with message data that is sent by one user to another.What i am trying to do is have it so (if users are online) they are notified - by a popup or something - that a new message has arrived for them.My idea was to create a trigger on the message table to update a change table with sender and recipient ids and date of change in it.Not a problem so far but what is troubling me is that i want the recipient to automatically query this change table every say 30 seconds to check if new message has arrived with their id.Tryed using ajax update panel and timer but naturally that kept posting back whole page - looks really terriable :( - tryed sqlnotification but as far as i can see that is only changing cached data for current data - not the same issue i think.Is there a way to query db table regualry without the client side knowing? - thinking along lines of how outlook requeries server for new messages and displays popup to say new message but doesnt interupt you if doing something else.Any help would be greatly appreaciated.Thanks

I am currently wrapping up a website upgrade for a client and I am working on a development server/database. The development server/database will become the live version. When the upgrade goes live, I will need to update that database with the latest data from specific datatables (no all of them) in the previously live database, but I don't know how to do a bulk refresh of datatables. Problem: specific datatables (not all datatables) from Database1 need to be updated with the data from Database2. Database1 and Database2 are copies of each other with vast differences in some of the data. Result: All of the current, up-to-date data needs to reside on Database1. Solution: Any ideas? I am using MSSQL 2000 and the databases reside on the same server.

I develop ASP.NET applications and use MS SQL 2000 Enterprise.
Each customer has one database and one custom design application. And, there is a gateway and a central database to get data from all databases.
Supposed there are 10 DBs. I want the data in those 10 databases updating to the central database directly. So, the gateway can gather all data of 10 DBs from a central DB.
Now, my question is how should I do it in MS SQL 2000? Can I do it with a stored procedure (SP)? If so, how does the SP like?
Or, SP can only perform on it's own DB, but not execute across DBs? If so, how can I do that?
Hi! I have quite strange problem, that I haven't seen before. When I use update command: UPDATE categorys SET banner_valid= '0', section_id= '1', main_cat_default= '0', banner= '', b_link= '', external_text= 'NÄ?kotnes parks ', in_frontpage= '1', name = '100. pants' WHERE (id = 130) Then the field EXTERNAL_TEXT should have value NÄ?kotnes parks but instead of this it makes it Nakotnes parks. I changed collation to Latvian and this did not work. But!!! When I open Enterprise manager and just type in NÄ?kotnes parks and save it then it is ok, but it does not work with Update/add script Any help or ideas???
I'm trying to update a single record in a table using data from a single record in another table. For the life of me I can't figure this out. I'm trying to avoid having to write a bunch of +=" string stuff in C#. Is there any way to do this with just SQL?Thanks in advance.
Hello All, I have two tables T1 and T2 with the same data structure. I need to compare T1 with T2 for all columns and update T2 for deleted, inserted and updated rows. How can I do this?
Dear All,I am facing a problem from last one month. I have around 100 of client user of my database. I am using VB application for the client users. When they submit the information most of the time the information submits properly. But twice or thrice a day no one can submit the information properly. It remains for more then 15 mins and it will sort out automatically. What might be the problem. Please suggest
My DTS package transfers data mostly codes from temp to master table. The master table has 10 description fields for each of the codes. These description fields are then populated using update statements joined with 10 description tables. However, the update process is so inefficient since a single update statement takes several hours to finish.
The second option is to populate description fields as codes are transferred from temp to master table using 10 left outer joins with description tables. But the result was unexpected. It's giving me more than twice as many records as there are in the temp table.
What would be the best (efficient) approach for this situation? Would greately appreciate any help/thoughts.
I want to add to a column in one table the data in another. I have tried different update statements and none work. My update statement currently looks like this:
update t1 set t1.amtYTD = t1.amtYTD + t2.Total from #ProgramData t1 join vw_MER_Reclass t2 on (t1.ProjId = t2.ProjId and t1.task = t2.task and t1.acct = t2.acct)
I need to take the amtYTD in table1, and add to it the value of Total in table 2.
