Hi,
I'm new to Telerik and have just downloaded the latest WPF trial.
I'm having trouble with the Gridview (version 2010.3.1110.35).
I'll post the XAML below, but I'm populating from an observableCollection pulled from a WCF service.
The grid populates OK, but I cannot group the columns please can you advise.
The window is binding to an ViewModel.

I've tried another sample wher I create some objects on the fly, putting them into an observableCollection and binding to it ... and
the grouping has worked fine.

Many thanks,
Joseph.

Hi,

I have a GridViewComboBoxColumn defined in my GridView in Xaml.  I have it set up to bind properly when I set the ItemsSource property on the GridView itself.  That works great.  I would like to know how to hide the combobox that is generated in specific rows when the Grid is bound based on certain criteria of the data items for each row.  How do I do this?

Thanks.

Hi,

        Now i m using the telerik rad map for show the details, and want to bind the shape file, but unfortunately i m using telerik q1 version, so i can't able to directly use that shape file, so i convert that as a kml file format. Now its working but i using some sample kml data's which is provided by telerik examples. but  when i look a deep look in my converted kml file, i see the values are in X,Y Values, so that i don't know How to bind this values in to the rad map, even weather rad map ll support this values or not i don't know, So plz

Explain me how to handle this, and how to convert the XY values in to decimal  latitude & Longitude.

Are any way to bind the xy values directly in the rad map control, using kml file.

Thank you

Here's my mainxaml.cs


Hi I have no problem on loading the child data related to its parent source. The problem is that if I try to expand another row it loads the first data for it. Example is if I have row1 expanded it displays the correct child table but if I go to row2 and expand it, its child records are for row1. I tried looking for the answer and putting the parent_IsExpandedChanged event to handle it but still it wont display the correct data. If I try to reload the application again and try to expand row 2 or row 3. its child is correct but if i expanded another row it will display the child for row 2 or row 3. Please help what am i doing wrong

How do I upgrade my Q2 telerik wpf to Q3? I tried searching cant find any

I get a NullReferenceException after clicking the GridView filter button in the following scenario:

1. The GridView has too many columns to fit in the current window so it has horizontal scroll bars.
2. I scroll the GridView content to the left so that column A is not visible anymore because it is now too much to the left.
3. I scroll back to the right so that column A is visible again.
4. I click the filter button of column A.
5. NullReferenceException is thrown.

I use the official Q3 2010 release of the GridView control.

Here are the exception details:

System.NullReferenceException was unhandled
  Message=Object reference not set to an instance of an object.
