I have a list of zipcode objects that I bind to a datagridview based on a selection from a treeview, the treeview is unimportant other than only a subset of available zipcodes are bound to the grid at any one time.


where GetForZipPart has a function signature of:


I want to select items in the gridview based upon another list of ZipGeoCode objects that correspond to a dealer.  The dealer list may contain zipcodes from other zipparts that are not bound to the grid.  I do the selection like so:



so far so good, however now when an item is selected or deselected in the radgridview I want to add or remove it from the _dealerZipCodes in the most efficient manner.  I suspect i shoudl use the radgrdiview_selectionchanged event.  I am wondering if ther is a way to do this with observable collections?.  Any suggestions greatly appreciated and info how I can act only on the item(s) that were selected/deselected by accessing the

SelectionChangeEventArgs

would be great.

I'm not using MVVM.

Currently my radgrdiview_selectionchanged looks like the following:


Not very efficient.

Thanks for the help/direction.

Hey guys,

I'm trying to sync my selected gridview row with the ICollectionView. I have installed an older version (2010.2.924.35) and the new version 2011.2.712.35. The same implementation works with the older version and don't works with the new version.

So, let have a look at my code:

The code of the ViewModel:


The XAML-Code:


The Items the ItemsView contains are correctly displayed in the GridView. But the OnCurrentItemChanged-Event is only being raised on startup (this.ItemsView.CurrentItem is null at this moment).

What can I do to get it work?

Thank you very much!

I need to build a chrome less window that has metro-styled controls to close, maximize, the window. I see DevComponents supports this but I'd prefer to use your tools. Do you support this? If so, how? I didn't see it in your demos/samples.

Hello,

We have come across an error when trying to use a date picker in a grid (v2009.1.413.35).  When you try to open a date picker that is being used in a grid an 'Object reference not set to an instance of an object' exception is thrown.  This problem seems to only occur on machines running Vista 64. 

Steps to reproduce:
1. Install the Telerik controls on a machine running Vista 64
2. Launch the Example app
3. Go to the GridView Editors example
4. Try to edit a date column

Here's the stack trace:
2009-03-25 14:22:40,609 [1] ERROR IRC.Gear.WorkItemManager.Wpf.App - Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object. at System.Windows.Automation.Peers.AutomationPeer.EnsureChildren() at System.Windows.Automation.Peers.AutomationPeer.UpdateChildren() at System.Windows.Automation.Peers.AutomationPeer.UpdateSubtree() at System.Windows.Automation.Peers.AutomationPeer.UpdatePeer(Object arg) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler)

Please let me know when there is a fix available.

Thanks,

Hello,

I have a panelbar inside of a Radpane. When I have my items (menu) on the PanelBar "expanded" and I pin or unpin the RadPane, I lost all my expanded items, and shows it all closed.

Any solution?

Thanks.
Regards.

I have a GridView with a column having two buttons: Edit and Delete. The GridView current item is the row that is highlighted that in some cases happens to be different from the row where the Edit/Delete button was clicked, therefore returning the wrong current item

Example: Grid has 4 rows. Row 1 happens to be highlighted. If the user clicks on either one of the Edit/Delete buttons in Row 2, we get Row 1 current item, instead of Row 2

Below is the XAML declaration for the Grid View

Hi Telerik Team,

I'm trying to create footer which will display elements count on predefined group .Net 4 with latest release of WPF controls (2011.2.712)

I'm using code below to create predefined group descriptor and later add aggregate funtion on column to show it in footer unfortunetly this is not working.

Hello,

We have definition of RadGridView with a GroupDescriptor:

<TelerikControls:RadGridView Name="grid" SelectionMode="Multiple" IsReadOnly="True">

   <TelerikControls:RadGridView.GroupDescriptors>

      <telerik:GroupDescriptor Member="Id" SortDirection="Ascending">

         <telerik:GroupDescriptor.AggregateFunctions>

            <telerik:CountFunction Caption="Models: " />

            <telerik:SumFunction Caption="Reslts: " SourceField="ResultCount" />

         </telerik:GroupDescriptor.AggregateFunctions>

      </telerik:GroupDescriptor>

   </TelerikControls:RadGridView.GroupDescriptors>

</TelerikControls:RadGridView>

If the user un-groups the grid and then groups it by "Id" over again,
information in the group header gets lost. Is it a bug?

Thank you,
Victor

Hi,

we're testing the breadcrumb control right now and would like to bind the Path property instead of using code behind (since we're using MVVM) however, even if that property already uses notify property changed, the breadcrumb is still not updating the path.

aside from this, we have several tree views and would like to update the itemsource for the control, but it isn't reflecting in the control as expected (a second click would reflect the new itemssource.
the data is okay if we





thanks!
