Update Certain Fields From A Grid View ?

Sep 25, 2006

Hi all,I asked a similar question a few weeks ago but I didn't explain myself to well so I was hoping for some more input.I have created a webpage in Visual web developer that contains a gridview that points to an SQL table.All works well as far as searching the table and sorting.  The SQL table itself is Droped ( deleted ) and then re-created every 1 minute from a query to a linked DB2 database  so that we have a "live" table of our DB2 system but in SQL.....However,There is now a requirement to be able to ADD data to this SQL table. eg: a comments field.. from the website.My procedure for re-creating the SQL DB is now useless as any data added through the website would be lost when the table gets re-created.What is the best way for me to achieve a permanent table in SQL that gets updated from the Linked server DB2 but that I can also add comments from the front end (Website Gridview)..I'm assuming some sort of update query and a join to a seperate, permanent table that contains the comments?.Please help. Ray..

Updating Grid View That Has Dropdown Lists

Jun 28, 2007

I have gridview bound with SqlDataSource control. One of the grid columns is a dropdown list which is populated programatically, (the gridview has template column with edittemplate field with dropdown list), dropdown Value contains of course collection of IDs.Please tell me how to declare UpdateCommand which will update the row with the dropdown list. The problem is with parameter regarding the column with dropdown list. When i declare this parameter and bind it to SelectedValue property of the dropdownlist from edittemplate tag - it doesnt work, because datasource control cannot see this dropdown list. So, how am i supposed to declare the ID of the row being updated in <updateParameters>? Thanks in advance!

Retrieving ID After INSERT Behind The Scenes - Not Using A Grid View

Jun 3, 2006

Hi there. I looked through many other posts describing scope_identity but I am trying to achieve the same thing from the code behind. i.e. I need to some how call a method to execute the insert command and then return the ID so I can update other tables with this value.
I was going down the road of something like:
addnew as sqldatasource = new sqldatasource
addnew.insertcommand = "Insert into....; def @NewID as scope_identity"
addnew.insert()
 
The problem is I don't know how to add a output parameter using VB or how to retrieve it.
Any help would be much appreciated, this is doing my head in....

How To Change Column Names In The Grid View Programatically?

Aug 31, 2007

I have consistent column names that load into a grid view. I now need to change the names in the grid view programatically. I was originally trying to get cute with SQL to do this, but I've been told my below solution will not work and I'm better off to do this in the presentation layer.  If this is true, remember I'm still wet behind the ears here...how do I do this in vs2005?
Here's my post to the SQL devs to give you an idea what I'm trying to do.
I have a query that grabs fields from a denormalized table. The result is column names Week1, Week2, Week3....Week26.  Users want to see the actual date instead of Week#. So I have a table (lkpdatecaptions ) that contains the fields "fldfieldno" and "Fldcaption". fldfieldno    Fldcaption-----------  --------------11             9/07/200712             9/14/200713            9/21/2007So fieldno 11 represent week1 and so on. So my hope is to update the alias with a query like: Select fldcaption from forecast.tlkpdatecaptionswhere fldfieldno = 11That quey returns the value of 9/7/2007 and is the value I need to represent the coumn alias name.My current query looks like this:SELECT  SUM(forecast.tblforecastdenormalized.fldwk01) AS WEEK1,So can I do something like the following?SELECT  SUM(forecast.tblforecastdenormalized.fldwk01) AS (Select forecast.tlkpdatecaptions.fldcaption from forecast.tlkpdatecaptions where fldfieldno = 11), ...

SQL 2012 :: How To Format Data In A Grid View (Pivot)

Oct 23, 2015

I am looking for a way to create a stored procedure that will show inventory availability. I would like to show the Inventory Name, The Date, and if the inventory is "checked out" using the ID name of the person who has the item.

For example it would look like this:

--------------------------------------------------------------------------------------------------
Inventory Name | 10/24/2015 | 10/25/2015 | 10/26/2015 | 10/27/2015 | 10/28/2015
--------------------------------------------------------------------------------------------------
Laptop | Tom | Tom | Tom | Avail | Avail
Projector | Avail | Avail | Avail | Avail | Bob
Air Card | Bob | Bob | Bob | Bob | Bob

It seems like I want to do a pivot table but there really is no aggregate so I am not sure what to use.

How Can I Return Data From A Database And Fill A Data Grid View?

May 2, 2007

Hi ! I have a textbox and a Search button. When the user inputs a value and press the button, i  want a datagrid to be filled.
The following code runs:
Dim connect As New Data.SqlClient.SqlConnection( _
"Server=SrvnameSQLEXPRESS;Integrated Security=True; UID= ;password= ; database=dtbsname")
connect.Open()
Dim cmd As New SqlCommand
Dim valor As New SqlParameter("@valor", SqlDbType.VarChar, 50)
cmd.CommandText = "Ver_Contactos_Reducido"
cmd.CommandType = CommandType.StoredProcedure
cmd.Connection = connect
cmd.Parameters.Add(valor)
cmd.Parameters("@valor").Value = texto
Dim adapter As New SqlDataAdapter(cmd)
Dim ds As New System.Data.DataSet()

Dynamically Creating Features Grid

Mar 17, 2006

I was given what at first seemed a simple task (and maybe it is, but with everything else on my plate, I can't seem to get my head wrapped around this)...create a grid or table something similar to below:
               Plan A           Plan B                  PlanC                  PlanD
Item1         yes                yes                        no                        no
Item2         yes                 yes                      no                        no
Item3         yes                  no                     yes                        no
etc.....
 
The "plans" are stored in one db table, the "items" in another. What I can't seem to get straight in my mind is how to relate the yess and nos and then generate a tabular layout similar to the above.
I don't need anyone to do it for me, but a push in the right direction would sure be nice (using SQL 2005) Thanks!
