serverside and Custom sorting

[Sampathkumar]

Hi,

Is it Correct for sorting data in serverside.

            if (e.OldSortingState == SortingState.None)
            {
                e.NewSortingState = SortingState.Ascending;
                if (this.Sort != null)
                    this.Sort(new RsRoutedEventArgs(TaskType.Sort, "tskstdsort", this, e.Column.UniqueName, "0", this.IsInTabPage));
            }
            else if (e.OldSortingState == SortingState.Ascending)
            {
                e.NewSortingState = SortingState.Descending;
                if (this.Sort != null)
                    this.Sort(new RsRoutedEventArgs(TaskType.Sort, "tskstdsort", this, e.Column.UniqueName, "1", this.IsInTabPage));

            }
            e.Cancel = true;

if correct then why it is not showing the sort icon.

thanks

Hi Vlad,
I am having similar problems, but the link you provided is no longer valid since you've moved to silverlight4.

Can you please provide some code examples?

Tnx :)

Hi boris,

Here is the link for the old Silverlight 3 demo:

You can check also this blog post for more info about server-side operations without RIA Services (with DomainDataSource the grid will sort on the server by default).

Hi Vlad,

Thanks for your reply.

Unfortunately, the example doesn't work for me :(

I am doing server side sorting, and have added the part that should change the visual state of my header, but nothing happens..

   private void gvData_Sorting(object sender, GridViewSortingEventArgs e)
   {
           if (!String.IsNullOrEmpty(e.SortPropertyName))
           {
               this.Columns[e.SortPropertyName].SortingState = e.NewSortingState;
           }
           e.Cancel = true;

           //server side sorting code below
           //...

   }

Header never changes visual state....
