Hi,
i have a question, i have a VS2005 and a SQL server 2000 enterprise in my office that i used for web developement,
iam new to this, i made a data driven site using some automated controls available in the toolbox, but i need to made some manual process, like i need to make a LABEL show the SUM of specific number fields from my data base, they say i have to make a OLEDB connection using VB, but i don't know how,
can you tell me how?
Thanks
hello...
Probably a simple question but I have to ask...using visual basic 2005 express...
I have two tables one with last name and basic info, one with detailed info. Both set up with Primary key and Foreign key.
I have a combo box that displays the last names and then by clicking
the last name, text boxes fill with the "other" data from table1,
however,
there are some text boxes that I would like to fill with data from the table2.
Any pointers??
I’m trying to teach myself C# and trying to create a simple (so I thought) little database using Infragistic's UltraWebGrid (Althought my question is more ASPish). Every sample I run across seems to only show the very basics and doesn’t seem to go into anything more than just a simple table and displaying it in a Gird. Which is pretty easy and I can do that all day and night.
Anyway, my database has three tables in a one-to-many relationship. The database is of Trucking companies and which states they service and they can service multiple states.
The database is like this:
Compnies:
TruckerID, Company Name, Address, etc.
ServiceStates:
TruckerID, StateID
StateNames:
StateID, StateName, StateAbbreviation
I would like to show the States that they service in a Hierarchical Grid.
I can write the SQL to do what I want to, basically do an inner join on ServicesStates and StateNames based on the TruckerID. I can sit all day and night getting what I would like to display in the WebGrid in the query builder on the SQL server. I figured it wouldn’t be much of a stretch to be able to do that in UltraWebGrid (Or whatever floats your boat).
Anyway, on to my question. :)
While browsing the samples on everything, I've figured out, that I will need to use the SqlDataAdapter Class, to access the database. Then I'll need to use the SQLConnection Class, and populate a DataSet.
Now while in VS I can go to WebSite -> Add New Item -> DataSet slap my tables on there and away I go (at least it seems that way). If I do that, what exactly is the difference between doing that and using the dataset class? When I do that, is that not creating the dataset? I see all the classes it created (I named mine Trucking). I see all the SQL statements in the classes.
I imagine I must be missing something *REALLY* simple or this just went way over my head at by at least 40,000 ft.
Thanks,
marly

please anybody can tell me a sample and simple example.
Thanking you
Hi, I have a page created within VS 2005 which uses a detailsView with a SQLDataSource which has insert, edit and delete items allowed with it. The problem is that if I delete a record I dont want to refresh the page as I want to set a label value to say item deleted. The problem then though is to select the item to delete I have a drop down which populates the details view on index change, but if I delete the item I cannot do a databind when its complete because it just binds to the existing dataset and does not do a fresh call on the database.Is there a command I can run to refresh the dataset on click of the delete button?Thanks
View 3 Replies View RelatedHey all,
I had a few questions about how to properly use the sqldatasource -
I have a form with a single dropdownlist, databound to an sqldatasource that just has a select statement. Over the course of time, the client has requested additional dropdownlists, all of which point to different sqldatasources. After I reached 4 or 5, I noticed the page started to load incredibly slower. I played around with the caching features, and after a good while of reading up on it, finally was able to cache the page /data and notice an increase.
Later, another 4 dropdownlists were added, 3 of which all take the same data. I assumed if I had 3 dropdownlists, which need the same data, I should use the same sqldatasource. What do you think? My page is behaving unaccepteably slow again.
As a test, I created a new page, and bound it in the same fashion. I slowly added more dropdownlists /sqldatasources, and found it lags a bit on the initial load time (maybe 10-12 seconds of processing time before the page loads). The tables it is pulling data from do not have a primary key, and i'm doing select statements that return roughly 100-200 rows of data (per dropdownlist on average). I'm only selecting 1 column name (no select * here)
I'm just curious if anyone has experienced similar issues, and also if there is anything I should do as a best practice while working with the sqldatasource. I've used hundreds of these on forms, and never experienced a problem. I only started noticing this on pages that have multiple. Also, when using multiple dropdowns that need the same data (I know that sounds goofy - why have 3 dropdownlists with the same data) should I use 3 individual datasources?
Thanks for your help in advance,
Mike
We are tired of null values coming out of from the database and we are directly coding behind UI decleratively.
We set up a null value coding standarts but I wonder what are the disadvantages to our approach
DataType The default value we send ALLOW NULL
int,bit,decimal 0 NOnvarchar(string) " "(one space) NOdatetime YESbinary YES
*in datetime we do not allow nulls in places such as _CREATEDATE and _LASTMODIFYDATE fields.
What are other approaches for null besides writing your own layer to handle it ?
Hello,
I would like to databind a textbox (the Text property) and I have try the following syntax:
Text='<%# Bind("au_fname") %>'
but there's no Datasource property for this control. I have defined a SqlDatasource object but can I link it to my Textbox. I have looked at the properties of the control: there's a Expressions section in which I can configure a connection string but thar's all.
When I run the page I have no error but the textbox field is empty.
Thanks for your help.
Does anybody know a good way to get a (near) live view of a sqlce database that doesn't involve ResultSets? I tried to use a resultset with the Sensitive option set, but it doesn't like the joins that I have to do in order to have the data make sense to the user.
Thanks
I have a windows form containing some text boxes and radio buttons bount to an SQL Server database, with code like the following:
this.tbBorrowerLastName.DataBindings.Add (new Binding("Text", dsData.Tables["Results"],"BorrowerLastName"();
this.rbMale.DataBindings.Add(new Binding("Checked", dsData.Tables["Results"],"Male"))
If I add a new row and try to move there using the code below, nothing happens (neither movement to a new position nor error message), unless I remove the radio button bindings. (The same thing occurs if I attempt to move to any record that has a null value in the database field for a radio button).
myLastRow = dsData.Tables["Results"].NewRow();
dsData.Tables["Results"].Rows.Add(myLastRow);
I attempt to move by changing the value of the position property of the BindingContext object.
How can I retain the radio button bindings and still be able to add and move to a new row?
Any help would be appreciated.

Hello,
I have a page with a detailsview where I can add articles (Generated by visual studio). Now the table contains a field (Autor) wich must contain the username of the Autor from the article. But when I run my page now I have to give it in manually ( in a textbox). I've searching for a way to bind the Profile Username with the insert Sql Query, @Autor value.
I tought maybe I should insert the value of the Profile username in the textbox and put the textbox visibel on false.

Can somebody help me?
Here's a new one I came across that stumped me for a bit.
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'xxxx'.
It appears that one of my dropdown menus was referencing the old SqlDataSource1for its data source id.
I had already changed the name of the of the id to something else though.
To fix it, I just updated the reference to the new name.
Thought I'd share, just in case

View 1 Replies View RelatedUPDATE #2: When it said "Do you want to install Microsoft SQL Server" I said "yes" and that caused it to work. I exited and re-ran and now the print runs w/o the "install SQL Server" (If the prompt had said "Do you want to install the print dialog" we wouldn't be having this discussion...)
UPDATE: After posting this i discovered that the same thing occurs when attempting to print the report direct from IE6: First a dialog pops up "Do you want to install this software?" Name: Microsoft SQL Server. When I click "Don't Install" I get the dialog "unable to load client print control." Since this happens direct from IE6 I suspect it's browser settings. I'll resume tomorrow and post a followup.
My WinForm C# app integrates Reporting Services by calling them from WebBrowser controls. The problem is attempts to print cause a dialog: "unable to load client print control."
I've read prior posts that say "enable Active-X in your browser" - I don't know how to do that from a WebBrowser control.
Any ideas how to support Reporting Services "Print" from within a WebBrowser control?

My development environment includes Visual Web Developer, SQL Server 2005 Express and SQL Server Management Studio Express. I have a .sql control string that creates a database. The control string is in my App_Data folder within my web site. When I use SQL Server Managment Studio Express to run the .sql control string and create the tables etc. it does it in my SQLEXPRESS folder and not in the web.
How do I run the .sql file so it will create the database in my App_Data folder within the web site?

Hi! I'm building a web application with ASP.NET, and using MS SQL 2000 for my database server.
How should I do to guarantee the integrity of the data in spite of the concurrent access? Meaning... how can I make sure that more than 1 user can update 1 table at the same time, while no error will occur? Do I need to add some codes at my aspx file? Or do I need to do something to my database? Or do I not have to worry about it?
Thank you.
If i use the TimeTracker app from the starter kit suite and I enter my SQL connection in the web.config file it works fine,
If i build a simple app with just a sqladapter, sqlconnection and dataset control then enter in the page_load procedure
sqlDataAdater1.fill(dataset11)
datagrid1.databind()
It keeps giving my errors see below: I created a connection with the sqlconnection control and used the same userid and password I used in the time tracker stater kit's web config file which works - I have no idea what is going on
*** is it better to create the sqlconnection control first then create the sqladapter or vise versa.

Do you have to use the sqldatasource in conjuction with another control like gridview or dropdown list?
I'd like to check to see if a record exists in one table before inserting data into another.
thanks
Hello.I'm new to ASP.NET and trying to write data to a Microsft SQL Server. I have created a SqlDataSource control, which is 'connected' to my SQL server.Now my question is how i can put data in the database throw the control, and read data from it. I've read the site, but it's still unclear for me..Greetings!
View 1 Replies View RelatedI'm writing a page to do some reporting off of one of our databases, and I'm using 3 control parameters for my sql query that feeds my datagrid. 2 of the ControlParameters are from dropdownlists, and one is from a RadioButtonList. The ControlParameters that reference the dropdownlists are both working well, but the one for the RadioButtonList is not.
The error I am getting is: Exception Details: System.Data.SqlClient.SqlException: Line 1: Incorrect syntax near '@Booga'. (I changed my ControlParameter name from DateStr to Booga to try to avoid any conflicts with reserved words.)Any ideas? Here is a snippet of my code:

Can someone please tell me what I am doing wrong...
I have a simple webform that has contains a GridView and a DetailsView. Once the GridView is populated the user simply selects a record from the list. The DetailsView is them populated with all of the data from the selected record.
The DetailsView is bound to a SQL DataSource/CustomerData. I have made sure that the DV control has the Edit/Update Command listed. The user can click the Edit button and successfully edit the fields but when the user clicks the "Update" button I am getting the following message.
Updating is not supported by data source 'CustomerData' unless UpdateCommand is specified
Why isnt the control handling the Update.
Many Thanks!!!!

I am trying to use the FileUpload control to save a filename to a SQL database. I'm using the OnUpdating event for my SQLDataSource to add the filename to the UpdateParameters. The OnUpdating event is firing but the FileName doesn't get added to the database. Any pointers as to why that might be would be very helpful.
Here's the code. Thanks much.
<%@ Page Language="VB" MasterPageFile="~/MasterPage.master" Title="File Upload Testing" %>
<script runat="server">
Sub Page_Load()
Response.Write("UpdateParameters(0)=" & dsLabel.UpdateParameters(0).Name & "<br />")
Response.Write("UpdateParameters(1)=" & dsLabel.UpdateParameters(1).Name & "<br />")
End Sub
Sub dsLabel_OnUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs)
Dim FileUploadControl As FileUpload = DetailsView1.FindControl("FileUpload1")
Dim strFileName As String = FileUploadControl.FileName
dsLabel.UpdateParameters(0).DefaultValue = strFileName
dsLabel.UpdateParameters(1).DefaultValue = Request.QueryString("rgstnID")
Response.Write("dsLabel.UpdateParameters(0).DefaultValue = " & dsLabel.UpdateParameters(0).DefaultValue & "<br />")
Response.Write("dsLabel.UpdateParameters(1).DefaultValue = " & dsLabel.UpdateParameters(1).DefaultValue & "<br />")
End Sub
