Hi,
I implemented Custom Sorting in GridView and it all works fine.
The only problem is that if I set e.Cancel = true; in the Sorting Event (as shown in documentation) Ascending and Descending markers don't appear in the Sorted Column Title. If I don't set e.Cancel everything works fine.
My only concern is that documentation says to set e.Cancel = true; when implementing custom sorting.

Thank you,

Midav

Hi Midav Obuarez,

If e.Cancel is not set to true RadGridView will also sort the data. If you would like to perform custom sorting you should set e.Cancel as true. Once you do that RadGridView will not sort the data. The EventArgs of the Sorting event will also allow you to configure the sorting state of the column. For example:

void playersGrid_Sorting(object sender, GridViewSortingEventArgs e)
{
    e.Cancel = true;
  
    // perform Descending sorting
  
        // set sorting state of the column
    e.NewSortingState = SortingState.Descending;
}


Kind regards,

Milan,

Thank you for your quick response. The way you described the process is also exactly how I undertsood it, unfortunately if you set e.Cancel=true, then the grid will ignore the settings of NewSortingState, so asc/desc marker will not appear in the column header.
So essentially I do things as you show in your email example, but it doesn't work properly.
If I don't set e.Cancel=true, everything works perfect but I guess internally the grid does some additional sorting which is not necessary in my case since I handle this myself. Here is my grid xaml, just in case.

<

 

Controls:RadGridView x:Name="dbgrdMain" Margin="3,0,0,0" IsFilteringAllowed="False" ShowGroupPanel="False" CanUserReorderColumns ="False" IsReadOnly="False" Sorting="dbgrdMain_Sorting" />

 


Thank you,

Midav

Hello Midav Obuarez,

That is very strange - setting NewSortingState in the Sorting event should be reflected in the column header. Could you please take a look at the application that I have attached to this thread - it will always set the sorting state to descending.

Milan,

Your example project does work for me as expected and it seems I do the same thing in my code so it's a mystery  for me why it doesn't work in my case, but thanks to your help I know it's not the problem with the RadGridView control, so I'll dig deeper into my code, maybe I'll find something.

Thanks again,

Midav

Hi Midav Obuarez,

If you could send us you code we can have a look to try to find the problem. I believe we had a bug which prevented the column header of being updated but this bug is fixed in version 2010.1 422.
