After i changed the size of the items (ColumnWidth and RowHeight), i get
sometimes an ArgumentException when I reorder items per drag-drop.
For the DataTemplate, i use a RadFluidContentControl
System.ArgumentException: '-42,-42,-42,-42' is not a valid value for property 'Padding'. at System.Windows.DependencyObject.SetValueCommon(DependencyProperty dp, Object value, PropertyMetadata metadata, Boolean coerceWithDeferredReference, Boolean coerceWithCurrentValue, OperationType operationType, Boolean isInternal) at System.Windows.DependencyObject.SetValue(DependencyProperty dp, Object value) at Telerik.Windows.Controls.RadTileView.OnDragInitialized(Object sender, DragInitializeEventArgs args) in c:\TB\101\WPF_Scrum\Release_WPF\Sources\Development\Controls\Navigation\TileView\RadTileView.cs:line 948 at Telerik.Windows.DragDrop.DragInitializeEventArgs.InvokeEventHandler(Delegate genericHandler, Object genericTarget) in c:\TB\101\WPF_Scrum\Release_WPF\Sources\Development\Core\Controls\DragDropManager\DragInitializeEventArgs.cs:line 94 at System.Windows.RoutedEventArgs.InvokeHandler(Delegate handler, Object target) at System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs) at System.Windows.EventRoute.InvokeHandlersImpl(Object source, RoutedEventArgs args, Boolean reRaised) at System.Windows.UIElement.RaiseEventImpl(DependencyObject sender, RoutedEventArgs args) at System.Windows.UIElement.RaiseEvent(RoutedEventArgs e) at Telerik.Windows.DragDrop.DragInitializer.StartDrag() in c:\TB\101\WPF_Scrum\Release_WPF\Sources\Development\Core\Controls\DragDropManager\DragInitializer.cs:line 169 at Telerik.Windows.DragDrop.DragInitializer.DragSourcePreviewMouseMove(Object sender, MouseEventArgs e) in c:\TB\101\WPF_Scrum\Release_WPF\Sources\Development\Core\Controls\DragDropManager\DragInitializer.cs:line 153 at System.Windows.Input.MouseEventArgs.InvokeEventHandler(Delegate genericHandler, Object genericTarget) at System.Windows.RoutedEventArgs.InvokeHandler(Delegate handler, Object target) at System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs) at System.Windows.EventRoute.InvokeHandlersImpl(Object source, RoutedEventArgs args, Boolean reRaised) at System.Windows.UIElement.RaiseEventImpl(DependencyObject sender, RoutedEventArgs args) at System.Windows.UIElement.RaiseTrustedEvent(RoutedEventArgs args) at System.Windows.UIElement.RaiseEvent(RoutedEventArgs args, Boolean trusted) at System.Windows.Input.InputManager.ProcessStagingArea() at System.Windows.Input.InputManager.ProcessInput(InputEventArgs input) at System.Windows.Input.InputProviderSite.ReportInput(InputReport inputReport) at System.Windows.Interop.HwndMouseInputProvider.ReportInput(IntPtr hwnd, InputMode mode, Int32 timestamp, RawMouseActions actions, Int32 x, Int32 y, Int32 wheel) at System.Windows.Interop.HwndMouseInputProvider.FilterMessage(IntPtr hwnd, WindowMessage msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at System.Windows.Interop.HwndSource.InputFilterMessage(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) at MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler)

Hello,
I was wondering if there is a way to check if a GridViewDataColumn's filter... is active or contains filtering. I have code that will execute depending if the column has filtering on or not.
Thanks,
Kiet

Hi,
I'm using WPF version of Chart component.
How can I get series value in the given X-axis location?
E.g. X-axis type is datetime and Y-axis type is double. So if I want to know series (y) values in specific time, how can I do that?
Regards,
Auvo

Hi all..
I want to use a gauge in VB 2010.So I will create a WPF user control project and add this into element host of my Final Winforms project(So now I have 2 projects in my solution). I have implemented this and its working fine also.
Now what I need is the end user ( he will be only using the winforms application) has to use this gauge control dynamically.
to be more specific, he wants to display output in gauge or in graph. so he has two options and he selected gauge and based on the parameters, SQL procedure is executed and the resultant dataset is binded with the gauge.
If he opted for graph then graph should be populated.
How can I achieve this
Thanks and Regards

Hello,
I'm using the Q1 2010 1.319 version of Telerik controls in a WPF application and I have a big mistake with RadGridView control.
When I initialize a RadGridView with a lot of rows, I have a black window which cover the entire screen and this window stays on top until the initialization isn't finished. When I say "on top" I would like to say that I can't see or put on top other windows (I can't back on my desktop too).
Is this problem is known ?
Thanks.

Hi,
I have a databound GridView and a RibbonBarButton conecting it to RadGridViewCommands.BeginInsert.
If there is data available (viewmodel.dataitems.Count > 0) then the BeginInsert Button is enabled, if no data is available - when I usually need the BeginInsert command - the button remains disabled.
If I set ShowInsertRow="True" and click on it, then the Button is enabled as well....
So, how can I enable the RibbonBarButton with Command="telerik:RadGridViewCommands.BeginInsert", CommandParameter="{Binding IsEnabled}" CommandTarget="my:GridView" for an empty RadGridView?
Thank you,
Hermann
