>>Hi everybody,

>>I am working on a complex web page that I originally copied from existing. I made bunch of the adjustments in it to point to the correct table. This page has a GridView with SQLDataSource and also DataSet is created in code.

>>I verified that all my SELECT statements in ASPX and aspx.cs for that page include the SiteID field (I added it).

>>However, in the method that creates an Excel file from it I have the following code:

>>DataSet dtsCopy = dts.Copy();

>>            dtsCopy.Tables[0].Columns.Remove("lettercode");
>>            dtsCopy.Tables[0].Columns.Remove("SiteID");
>>            dtsCopy.Tables[0].Columns.Remove("deleted");
>>

>>
>>and the second line is failing (Column SiteID is not found).
>>
>>Do you know where can I find why I don't have SiteID in the DataSet? Is there any other file in addition to the ASPX/ASPX.cs I have to re-check?

True. But why do you mention this?
