DataSource Controls :: How To Write A Query Which Reads Data From Optional DDL's?
May 5, 2010I have couple of DDL's which let user choose couple of different values from it. Once the user has made his selection he clicks on the "Submit" buttion which redirects the user to the other page, which then displays table from backend SQL DB. The pages are named Page1.aspx and Page2.aspx resp. I am using Querystring to carry forward the values of the DDL's to Page2.aspx.
How can i modify the query in such a way that even if one of the DDL's is left blank the Query would ignore that and shall produce the table considering value of DDL2 in the where clause. In case both the DDL's are empty then the query will not have a where clause and shall showcase the complete table as such. I've written a query for this but it's not working the way it shoul.Here is my code for the SQLDataSource: [Code]....

View 3 RepliesVerbatim - Why Write @ Before Sql Queries - Select Data From Database Then Write Query?
Oct 1, 2010Suppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?
DataSource Controls :: SqlDataSource And Parameters Query / Trying To Accomplish Is Building Dynamic Query
Aug 22, 20101. 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.

View 10 RepliesForms Data Controls :: Programmatically Adding Conditionals To A Gridview Query?
Oct 31, 2010I have a gridview databound to an sql source returning about 1300 records (cars). I have listboxes to narrow the search (model year, manufacturer, segment). What is the most efficient way to tie these listbox selections to the gridview query?
Right now I am piecing together my own sql query string and replacing the SelectCommand. This works, but I keep running into timing issues where the command reverts back to the coded initial value. I can continue debugging this, but is there a better way?

View 5 RepliesDataSource Controls :: Accessing FK From A Query Via Entity Query
Jan 21, 2010I'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?
