DataSource Controls :: SqlDataSource And Parameters Query / Trying To Accomplish Is Building Dynamic Query

Aug 22, 2010

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.

DataSource Controls :: Accessing FK From A Query Via Entity Query

Jan 21, 2010

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?

DataSource Controls :: Use Login Name In A SQL Query?

Nov 24, 2010

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"

DataSource Controls :: SQL Query Formation?

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).
