[Solved] RadGridView Sorting Order

[Leon]

Hey All,

I have a RadGridView with several columns in it...some strings, some DateTime, Some Integer.

I need a way to sort these columns...I am overriding the Sorting event and doing my sorting as such:

IOrderedEnumerable<TableViewRow> sortedValue;

                        sortedValue = from item in dgStudyList.Items.OfType<TableViewRow>()
                                      orderby ConvertToDateTime(item.Data[columnName] as string) ascending
                                      select item;

grid.ItemsSource = sortedValue.ToList();

this works fine and is okay.

The problem I run into is I want to do an initial sort on the table on initialization.  When I use the SortDescriptors property to sort, it sorts by string...not by int or dateTime (which works for the columns which have strings in them).  However, if I initially do the sort using the above method (which is needed to sort by date, or int), the little triangle in the row headers (which show sort direction) do not get set.  This seems like a pretty strait forward problem. 

Is there any way to set those or do a sort which will set those arrows accordingly.

Thanks

Leon

Hello Leon,

 Why not create a model with additional DateTime property on the top of your original data and let the grid to sort instead?

Hey,

Thanks for your reply.

Sorry for being so green, but I am kind of new to this.  Can you point me to an example I can work from?

Thanks

Hi,

 The idea is to create new class and inherit from your original class. You can add new DateTime property to this new class.

Hi All,

I have applied sort settings to my Silverlight RadGridView collumn. my code is something like this

grid.SortDescriptors.Clear();

 

foreach (SortSetting setting in Settings.SortSettings)

 

{

Telerik.Windows.Data.

 

SortDescriptor d = new Telerik.Windows.Data.SortDescriptor();

 

 

d =

 

new Telerik.Windows.Data.SortDescriptor();

 

d.Member = setting.PropertyName;

d.SortDirection = setting.SortDirection;

grid.SortDescriptors.Add(d);

}

I have some editable collumns on my grid so after adding these descripters when i try to edit fields on grid then after editing when i move to other row the grid gets reloaded.

i tried to chk wether it is sorting or loading again but these events is not fired.
plz help me this is very urgent.
