ASP.net SqlDataSource - use different query based on selection in DropDownList

Hi

I have a GridView on an ASP.net WebForm. It currently has a SqlDataSource that I set up very quickly. I want the user to be able to choose between two possibilities in a DropDownList and load the GridView with a different SQL query from the same data source.
What is the best way to do this? Should I use two SQLDataSources?

You can do that by resetting SelectCommand ( SqlDataSource1.SelectCommand = "SQL-query").

E.g.,
Protected Sub btnBindGrid_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnBindGrid.Click
	'SqlDataSource1.SelectCommand = "Select * from Table1"
	
	If DropDownList1.Text = "sample1" Then
		SqlDataSource1.SelectCommand = "Select field1, field2, field3, field4 from Table1"
	End If

	If DropDownList1.Text = "sample2" Then
		SqlDataSource1.SelectCommand = "Select field1, field2, field3 from Table1"
	End If

	If DropDownList1.Text = "sample3" Then
		SqlDataSource1.SelectCommand = "Select field1, field2 from Table1"
	End If
End Sub

Open in new window

Try like this. It may work for you.
