Hi,

The Visual Studio C# Examples Solution is not buildable.
The first error is in CarDashboard.Example.xaml.cs (Line #91): 
-  no overload for method 'Begin' takes '0' arguments

The C# Samples application crashes also after a few seconds.
 
My Environment:
- CLR3.5
- VS2008SP1
- Silverlight 2.0
- SQL Server 2005
- Telerik Build 2008.3.1105.35

Btw. The online WPF (Silvelright) demo does crash while switching from one sample to another.

Cheers,
Jani

Is there a way I can modify the colors on the simple theme?

(using the grid) When an item is highlighted, I want the text color to be white instead of black.  Thanks

Hi there,

We are trying to incorporate RadGridView (RadControls for WPF Q2 2008) into our solution with Blend.

However we are unable to preview the Grid and that's odd, because it does work perfectly fine when copy&pasting the XAML code into any other solution that we have tested.

We are working on a large WPF application using .NET Framework 3.5 and yes, we have added all references to Telerik dlls.

Any clues as to what is preventing the preview of of the RadGrid View from within Blend?

Thank you all.

I installed it to test to see if it's good for me, but it keeps crashing every couple of seconds, whenever I click anything in the DEMO window.
My OS version is Vista 64-bit, I have installed VS 2008 and .Net framework 3.5 SP1.
Thanks.

I am using the wpf treegrid and want to be able to drag only certain items into only certain drop targets within the tree.

I noticed all of the querycontinue and other Wpf drag drop events do not fire at all so the only option I have to choose if a target is valid or not is what the documentation references: the IsDropAllowed property on the RadTreeItem itself.

the problem with this is all it does is suppress the preview from actually moving the item in the tree. I need to be able to change the drag icon to some sort of indicator saying the target is invalid. Just like WPF allows with its DragEventArgs.Effects = DragDropEffects.None

any help is very much appreciated. It seems rediculous to recurse through the entire tree on every DragStarted eventHandler and set the isDropAllowed to true or false for each node. But even if that is the only acceptable method for some strange reason, it should at least work and change the cursor to an (X)

Hi,

I was wondering if it is possible to remove the blue mouse-over effect that appears on the content area of a RadPanelBarItem. I can override the colours for this effect on the header of this control, but can't find a way to remove or disable it on the content area. I am currently using the 2008 Q2 SP1 release of RadControls for WPF.

Thanks in advance,

Craig.

Is there a way to accomplish loading data on demand with WPF GridView?
That means gridview should ask me how much DataItems to render to show an appropriate scrollbar.
Then when you scroll dataitems into view,  GridView fires an event, where in I can load only that data that is visible.
I not only need UI virtualization but rather data virtualization.
If not, does GridView support paging like asp.net Gridview?

Hi,

I've update to the last version but now i have 2 problems with it
  1. When i get the gridviewcell from a dependancy object and then try to get the field property (what existed in the previous versions), it doesn't exist anymore ? (the code comes from a datacombo selection changed in the grid)
     DependencyObject item = e.OriginalSource as DependencyObject;  
     while (!(item is GridViewCell))  
     {  
         item = VisualTreeHelper.GetParent(item);  
     }  
     
     
     
     if ((sender as ComboBox).SelectedItem != null)  
     {  
        PrinterTray p = (sender as ComboBox).SelectedItem as PrinterTray;  
                            QueueItem q = ((item as GridViewCell).Field.Record as DataRecord).Data as QueueItem;  
                            q.SetPrinterTrayKeys(p.ReportServiceId, p.PrinterId, p.PrinterTrayId);  
     } 
  2. When i add a column that is set to a nested object then it doesn't work anymore (worked fine in the previous versions) but now it doens't display anything. (QueueItem.Status.StatusId)
    <telerik:GridViewDataColumn Width="Auto" DataType="{x:Null}" HeaderText="StatusId" UniqueName="QueueItem.Status.StatusId" />

Dear All

We are using an editable row within a RadGridView and the RadGridView appears to be hooking the PreviewKeyDown or KeyDown event and changing the focussed element in the visual tree when the down arrow key is pressed anywhere inside the grid.  This manifests itself as focus shifting away from, say, a text box when we press the down arrow key in it.

Something along the top edge of the grid is receiving focus when we do this, but we can't identify this thing when we use Snoop.  We're just seeing a dotted line above the column header row in the grid.

Can you check the code and see what's going on?  Our editable row is used elsewhere in the app outside of a grid and pressing key down in a text box has no effect.

Regards

Chris Smith

I would like to request a feature where you can set a minimum date and a maximum date on the DatePicker control. Ideally this would be a dependency property so that you could bind to it.
