Hi All!
I've this strange DataView sort bug and i can't do any sorting
activities! Below is my code...
---VB.NET Code---
dvFinal = New DataView(objDat aSet.Tables(CON _FinalTable))
Dim strSort As String = drpOrderBy.Text & " " & drpOrderStyle.T ext
dvFinal.Sort = strSort
Response.Write( strSort)
---End VB.NET Code---
And I got the following error...
---Error Message---
Exception Details: System.IndexOut OfRangeExceptio n: Cannot find column ASC
---End Error Message---
I don't know why DataView is treating sort expression "ASC" as the
column name!!!
Please help!!!
Thank you all in advance!!!

Have you eliminated the possibility that drpOrderBy.Text is empty?
So that what actually gets passed in is " ASC" instead of "columname ASC"

Hi Alvin,
Thanks for the reply! Yes, I've eliminated that. You can see the
following code in my previous post...
Response.Write( strSort)
which indicates that I've been madly testing the value of strSort and
tried setting the dvFinal.Sort property again and again :)
Any other ideas?
Thank you!
MK
Hi Norman,
Thanks for the reply.
I've tested for example...
dvFinal.Sort="C ustomerCount ASC" and it worked fine. Only when I do
through the variable.
Also drpOrderStyle is not a DropDownList, it is a Textbox. It was named
using drp* prefix because it WAS a DropDownList but now I'm using the
TextBox. I just continued to use the same name so I don't have to change
the code while I'm in the testing phase.
Furthermore, I'm not the only one experiecing this problem (or bug???),
for example... http://groups.google.co.nz/groups?hl...%2522DESC%2522
The thing is that I can say Response.Write( strSort) and I can see the
"CustomerCo unt ASC" appearing on the ASPX page. So why doesn't DataView
is not accepting this? Why is it treating ASC or DESC commands as column
names ?!?!?!
Thank you!

Just curious: are drpOrderBy and drpOrderStyle DropDownLists in System.Web.UI.W ebControls namespace? The way you name them indicates they are DropDownList, but DropDownList does not have property "Text". May it be the cause of your problem?

Hi
I'm creating a dataview "on the fly" in order to sort some data prior to writing out the information to a MS SQL table
I have used two methods in order to determine the sort order of the DataView. (I'm writing in C# with the v1.1.4322 of the .NET Framework, in Window2K server"). First of all, here are the two methods I have used in order to apply the sorting property to the DataView

I have a dataview in which the sort property will not sort the dataview.
Here's is a simple scenario similar to what I am doing:

' Returns a DataView with 2 columns and 3 rows

Is it possible to somehow sort a dataview, all on one column, but on
different variables?
That is, I have a 'Title' column in my dataview and I'd like to display
first all "Directors" (sorted), then everyone else (sorted). I've used the
'ItemBound' but can't figure out how to do this with that procedure.
Thanks in advance, any ideas are appreciated.
