label text, just not the sort.

System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here

lblWhatClicked.Text = "You clicked: " & e.SortExpression

Try changing the followin
dv.Sort = e.SortExpressio
t
dv.Sort = e.SortExpression & " ASC
The way you are doing sort will only handle one way sort (i.e. all columns can only be sorted in ascending order). If you want to be able to sort a column both ascending and descending order you'll need to do some more work
The following is a good article on customizing the DataGrid control. There is a section on how you can implement 2 way sorting (search for What about Sorting? in the article) http://msdn.microsoft.com/msdnmag/is...ng/default.asp

Suresh...thank you for assisting. I added the & " ASC" as you suggested.
Unfortunately, that did not change anything...the datagrid still not
sorting...it is posting and running the Sub as evidenced by my
lblWhatClicked.Text = "You clicked: " & e.SortExpression, but the table is
still un-sorted.
Could you take another look?

Seems like we're almost there. I realized I had a SORT BY ASC command in my
stored procedure that may have been hindering. I still unable, however, to
get either the pre-are postback code to sort in either direction. To
simplify and troubleshoot, I'm just try to sort ASC by a specified field in
the the initial load of the page, and then sort DESC by the same column in
the event of a DataGrid1_SortCommand.
No sorting is taking place at all with what I have here, though.

No this is ok. Because when you sort the DataView it's already detached from the DB and does a fresh sort on the recordset with the criteria specified by the user (i.e. clicking on the columns)
Damn, again another mistake by me. Although it does work either way in my sample DataGrid1.DataSource = DsAdvanced1.Tables("sac1SelectSurvey1").DefaultVie
Instead shoule b
DataGrid1.DataSource = d
Finally in the DataGrid1_SortCommand method
Dim dv2 As DataView = DsAdvanced1.Tables("sac1SelectSurvey1").DefaultVie
dv2.Sort = " clnName DESC
'e.SortExpression &>DataGrid1.DataSource = DsAdvanced1.Tables("sac1SelectSurvey1").DefaultVie
DataGrid1.DataBind(
dv2.Sort = e.SortExpression & "DESC
o
dv2.Sort = e.SortExpression & "ASC
You have the followingdv2.Sort = " clnName DESC
This will always sort by clnName DESC everytime you click on a column header
Change it to the way I've described above and see if it'll work

Suresh,
Nope, still same thing.
Should I have a special "Imports" statement at the top of this user
control's code-behind? Currently I don't have any.
I'm using SqlDataAdapter remember. Although I'm assuming that if there was
a problem with Imports, it would not even render what data I have.
