When you bound a GridView using Visual Studio it generates server side HTML code. I try to make it 100% source code in VB.NET. I have the following ASPX file:
The above code works fine but when I try to declare the SqlDataSource1 object using VB.NET for some reason it does not work:
It does not cause any error but nothing appears on the screen. Can someone help me to solve this problem?
Thanks in advance.
VB.NET:

SqlDataSource1.DeleteCommand = "DELETE FROM [Table1] WHERE [ID] = @ID"
SqlDataSource1.DeleteParameters.Add("ID", System.Data.DbType.Int32)
SqlDataSource1.InsertCommand = "INSERT INTO [Table1] ([Voudou]) VALUES (@Voudou)"
