Hi,

I implemented my own paste handling. Therefore I set the property RadGridView.ClipboardPasteMode to GridViewClipboardPasteMode.None. This worked perfectly for version Q3 2010. Now I update to Q2 2011. With this version my handlers of the command ApplicationCommands.Paste are not invoked any more. I noticed that now the method GridViewDataControl.PasteCanExecute contains the statemente: e.Handled = true. I think this does not make sense for GridViewClipboardPasteMode.None.

Is this a known issue? Will it be fixed? Is there a workaround?

Best regards

Uli

Hi,

In the past, I've managed to successfully create a sort of time marker that show the current time. This marker worked fine until I upgraded to the newest version of RadControls in order to utilize the new AllDay Event-functionality.

Screenshot

Because of the new AllDay-area in the top of the calendar, my time marker shows the incorrect time. The algorithm used to calculate the position of the marker needs to know the height of the actual schedule (the scrollable area, marked with a long red line in the screenshot) in order to work. Earlier, I resorted to using the schedule's ActualHeight-property - a hardcoded static value (that corresponded to the group header height). However, this won't work now, as every AllDay Event changes the height of the group header area.

This leads me to the question; Is there a way of getting the height of the group header-part of the schedule (marked with a short red line on the screenshot) or the actual schedule (marked with a long red line on the screenshot)?

Thanks,
Kristian

I use the MenuItem IsSeparator sucessfully in dropdown menus but the separator is not showing when used in the main menu bar...

EDIT: I added a default style for the menu item and it now displays a "horizontal" separator bar... How can I make this bar vertical ?

In many examples, I see the use of the TileStateChanged event to manually control the tile state. In every example, the first line of code in the event handler is this:

RadTileViewItem item = e.Source as RadTileViewItem;

But when use the same code in my own handler, the e.Source reference is to the RadTileView, not RadTileViewItem. Just to note, I'm wiring the event up in xaml using the following:

<my:RadTileView x:Name="ClassOverridesTileView" 
                        ItemsSource="{Binding Classes}" 
                        ItemTemplate="{StaticResource HeaderTemplate}"
                        ContentTemplate="{StaticResource ContentTemplate}"
                        TileStateChanged="ClassOverridesTileView_TileStateChanged"
                         >
        </my:RadTileView>

Why would the source of the event be different for me than the examples?

Hey there,

I'd like to get rid of the shadow of the vertical splitter shown once you fix a column.
Is there any way to override the style and remove the shadow?


Thanks a lot!

I am using the RadMenu as my standard window menu for an application that I am developing. An issue has arisen that menu items which have an Icon image. When the menu option is disabled, the Icon image appears to be being moved one pixel to the right, causing the border between the Icons and menu text to become misaligned. This results in an unsightly jagged line appearance in the overall menu.

Below is the XAML for the Edit menu of my application:

Any help on what could be causing this or possible workarounds to this issue would be greatly appreciated.
