I can't get my RadComboBox to filter. I have  IsEditable="True"  IsReadOnly="False" IsFilteringEnabled="True" TextSearchMode="Contains" VirtualizingStackPanel.IsVirtualizing="False" . So why won't it filter? Do I need something else?

I have a grid with a column whose CellTemplate is being set dynamically on each row via the CellTemplateSelector property of the column.  The cell will either be a checkbox, textbox, combobox, or datepicker.  The controls are showing correctly, and they are binding correctly.  However, when I tab into a cell in this column, I have to tab twice to actually be able to modify the data.  The first tab puts the cursor into the correct cell but not into the embedded control.  The second tab puts the cursor into the control.  Is there a way around this?

Also, is there a simple way to get the cell to respond to the Enter key after editing data in one of these controls (specifically the text box) rather than having to tab or click out of the cell?  I'm sure I could probably handle KeyUp or KeyDown events to make it work, but I was looking for a way to handle it within the XAML.

Thanks,
Ben

I have a DynamicLayer and my own implementation of IMapDynamicSource

I have implemented ItemsRequest, and it returns the MapPinPoints from an Observable collection.  However, if I alter the Observable collection, then how can I make the DynamicLayer call the ItemsRequest again to see if any of the new points are now visible?

Hi,
I have a data object class with System.ComponentModel.DisplayNameAttribute attribute.
When setting grid's ItemsSource with a collection of this data object, I see that the overriden DisplayName property getter is called by the grid, even though I set the Header property of each column hard-coded, and AutoGenerateColumns on the grid is set to false.

Is there a way to disable the grid's usage of this attribute without removing it from the data object?

Thanks,
Regards,
David.

Hi,

I have defined a dynamic layer, and I am trying to deliver up RadCharts.  As per your examples, I set the MapLayer Location Property on the RadChart.

If I add the charts directly to an InformationLayer, then they work
If I add them on the dynamic layer I get the following exception

Specified index is out of range or child at index is null. Do not call this method if VisualChildrenCount returns zero, indicating that the Visual has no children.\r\nParameter name: index\r\nActual value was 0.

   at System.Windows.FrameworkElement.GetVisualChild(Int32 index)\r\n   at System.Windows.Media.Visual.InternalGet2DOr3DVisualChild(Int32 index)\r\n   at System.Windows.Media.VisualTreeHelper.GetChild(DependencyObject reference, Int32 childIndex)\r\n   at Telerik.Windows.Controls.RadChart.PopulateLogicalChildren()\r\n   at Telerik.Windows.Controls.RadChart.OnApplyTemplate()\r\n   at Telerik.Windows.Controls.Map.DynamicLayer.MapSquares.CheckVisibility()\r\n   at Telerik.Windows.Controls.Map.DynamicLayer.RequestSlices(Int32 matrixIndex)\r\n   at Telerik.Windows.Controls.Map.DynamicLayer.ProcessRequests()

Is there something that I am not doing properly.

Thanks
Simon

Hi,

I have turned off Spring Animations so that when I pan or zoom the map, the shapes in the information layers do not lag behind the tiles.

This works fine, apart from when zooming in and out the shapes are drawn in slightly the wrong place.  I then need to pan the map slighly in order to get the shapes back in the correct position

If I turn on Spring Animations again, I get the time lag, but they are always in the correct position

You can see what I mean from my screen shot

Hi,

I'm new to the telerik wpf controls and I want to know if there is a way to make use of the RadToolBarTray and use it in place of the standard notifier control? Does telerik have anything that improves upon the  WinForms.NotifyIcon or the context menu for that control? I didn't see any previous samples or forum posts related to the tray icon.

Thanks,
Scott

We are building a custom AutoCompleteBox using the RadGridView control internally. We are binding the ItemsSource against a IQueryable(Of T) from NHibernate and using the CustomFilterDescriptor from this article.

When using only one filter member it works:

But when using more than one, like this:

Throws an ArgumentException: An item with the same key has already been added.

We are using the latest Q3 beta assemblies.
