DataSource Controls :: SQL Query Migration?
Mar 30, 2010
I am having some trouble querying a SQL Express DB from my ASP.NET 3.5 application. I am new to ASP.NET 3.5, only having used ASP in the past.In ASP, my code would be:
Dim db
Set db = Server.CreateObject("ADODB.connection")
'Opens the db connection string stored in another asp webform [code]....
This code creates the connection to the database, assigns the variable SQLi with the query, and assigns the execute command for that query to the variable RSi.
In ASP.NET, I have managed to get this far:
'The connection string is stored in web.config [code].....
I am unsure how to do the next part, when the individual id is assigned to the variable GEN1i (the syntax .fields does not appear to work for me).

1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.

This query works perfectly on the query analyser.
But when configuring the Table adapter ,I try executing the query and i get 0 rows affected.
What could I be getting wrong in this case.
NB:Existing GalleryID has been supplied.

I've got a query such as
Dim MediaQuery =
From m
In dB.DOWNLOADS _Where m.ID = id _Select
which returns a record from the database. One of the fields in the record is a FK to another table. I need to read this value to be able to set a dropdown based on the ID but I can't work out how to access it. For a standard record I can just do the following txtTitle.Text = MediaQuery.FirstOrDefault().TITLE
However with the foreign key it doesn't work like that. I've tried drpGroup.SelectedIndex = MediaQuery.FirstOrDefault().DOWNLOAD_GROUPS.ID where DOWNLOAD_GROUPS is the FK field but it returns Object reference not set to an instance of an object. If you're simply wanting to read some values from a single db record in the entitiy framework and one is a foreign key how should I go about getting the value?

I am using Querystring "ddl4" to pass on value of a drop down list to the next page where I am using that value in the WHERE clause of a SQL command. I also need to check whether ddl4 is blank or not which I do using If Else in SQL command. I am not able to run the query where the Querystring ddl4 IS NULL
This is the sample link with the Querystring ddl4 carrying a blank value:

I'm creating a web project in ASP.NET (C#) using Visual Studio 2010. I'm using the built-in login page. Here is what I'm trying to achieve.I want when a user logs in, the default.aspx page will display all his information including firstname, lastname, email address... I created a database table to store all users information (SQL). I want to use the "login name" as a parameter in "SELECT * FROM usertable WHERE username = loginname". From the code-behind (default.aspx.cs) I can pull the current loginname with "this.User.Identity.Name" but I can't pass this information to the query command in the default.aspx page.For example, when Jim logs in with his user name as "sirjim", I want to use"sirjim" in place of "loginname" in default.aspx page.Code in default.aspx page:
<asp:GridView
ID="GridView1"
runat="server"

I have several dropdowns in ASP.net, I want the contents in each dropdown depending on what is selected from the above dropdown and the datasource queries reflect this. I have the queries correct for the first two dropdowns, but I cannot get the third displaying data.
The first dropdown just contains all dept names
The second dropdown contains the manager names in that chosen dept above
The third is meant to contain the list employees relating to the chosen manager name above
<asp:Label ID="Label1" runat="server" Text="Cost Centre:" Font-Bold="True"></asp:Label>
<br />
<asp:DropDownList ID="DropDownList_CostCentres" runat="server" Height="21px"[code]....

The variable has already been declared and stored upon page load. I just need some way to get it within the SQL query for the datalist.
<script runat="server"> Sub Page_Load()
Dim ID As String = "D07AD7E0-8E34-4C18-9B4D-10576B0CC6BF" End Sub

From ISDS_454.dbo.Books, ISDS_454.dbo.booksusers, ISDS_454.dbo.Genre
where ISDS_454.dbo.Books.ISBN = ISDS_454.dbo.booksusers.ISBN
And ISDS_454.dbo.Genre.Genre_ID = '1'
And ISDS_454.dbo.booksusers.userID = 'D07AD7E0-8E34-4C18-9B4D-10576B0CC6BF'">
