I have a Procedure which should return only 1 Record on selecting record according to Priority.
BEGIN
DECLARE @Accounts nvarchar(MAX)
SELECT @Accounts = ISNULL([map_user_modules].[Accounts], '') FROM [map_user_modules]
WHERE [map_user_modules].[id_user] = 231 AND [map_user_modules].[id_module] = 5
IF ((@Accounts = '') OR (@Accounts = 'All'))
SELECT @Accounts = null
BEGIN
Select @@ROWCOUNT as Priority2
END
IF @@ROWCOUNT = 1
BEGIN
Return
END
BEGIN
Select @@ROWCOUNT as Priority3
END
IF @@ROWCOUNT = 1
BEGIN
Return
END
BEGIN
Select @@ROWCOUNT as Priority4
END
IF @@ROWCOUNT = 1
BEGIN
Return
END
In the above statement Suppose we take a scenario where Select @@ROWCOUNT as Priority3 is executed, I get two tables returned, One is the Table returned by Select @@ROWCOUNT as Priority3 and the other is the Table returned by Select @@ROWCOUNT as Priority2 which has no Records. How can I eliminate the Empty table that returns no records.

I'm returning one table. My understanding is that a DataSet can be made of more than one DataTable. I also understand that I can use either of these to return my one table.
Is it better to use the DataTable when I have one table to return instead of a DataSet? Is there any advantage of not using the DataSet in a situation like this? Is there a disadvantage to using the DataSet when only one table is being returned? Does this even matter?

I have a gridview and i wanted to add a row when the gridview is empty, so that the header would be shown anyway. I have read about it on the web but i can't quite understand where exactly should i add the row.
My grid is binded by a sqldatasource. I am already adding a second header for the grid (to display some filters, and they need to be shown even if there are no results so that the user can perform another "search"), on rowCreated event, so, where am i supposed to add the row? Which events are fired even if the gridview is empty?

I've got a gridview in which I have a footer that I use to insert rows into the grid. However, if the grid is empty no data is displayed (including the footer). Is there a way to still show the footer row so a user can insert additional rows into the grid despite it starting out as empty?

I am trying to show the footer template of a gridview on page load when there is no data in the database. The reason why im saying page load is that I have code to actually pull data from the database instead of a datasource.

I need to pass the data from GridView1 to a DataTable, and then pass the DataTable to GridView2 and preview it. I have BoundFields and ImageFields in the GridViews. I think I am doing something wrong but I can't figure out how to do it. I know I have to iterate through the GridView.Rows, but I don't know how to pass it to the DataTable.

I have one gridview and i want to take all the values in a datatable or dataview.
I tried like this
DataTable gridTable = (DataTable) dataGrid1.DataSource;
but gridTable is showing null, it should not show null because gridview has lot of records with 3 columns
Is there any way i can convert/store a gridview.Datasource records in a datatable or dataview?
