Hi Doug,
Is this issue and continous one from the previous checkbox list query one?
I think you've now be able to query the data based on the checkboxlist's
selection status, and your current difficulty is how to do some
customization on the page depend on whether the returened query result is
empty or not, correct?
If this is the case, would you show me the code on how to query the result
and how to bind it to the databound control(DataGrid or Gridview) or are
you still using a SqlDataSource control?
If you are programmtically call ADO.NET SqlCommand or TableAdapdter to get
the DataSet, I think you can set the CheckBoxList.Visible to false in your
code after check whether the returned DataTable is empty.
If you're using SqlDataSource control, I think you may register its
"Selected" event, and use the "AffectedRows" parameter propertyto determine
whether there is any row get returned. e.g.
===============
protected void SqlDataSource1_Selected(object sender,
SqlDataSourceStatusEventArgs e)
{
Response.Write("<br/>AffectedRows: " + e.AffectedRows);
}
=================
If there is anything I have omited or if you have any parituclar
requirement, please feel free to post here.
Sincerely,
Steven Cheng
