Hi,
I am using RadGridView in WPF application and binding it to a DataTable view. For my RadGridView I have set AutoGenerateColumns as "True" (to get my columns automatically).
Problem: In DataTable object (which I am binding to RadDataGridView) I have one DateTime column. In RadDataGridView it only shows Date calender in the dropdown for picking date, but no time. More over I want to change date format for DateTime column. As AutoGenerateColumns is true, I don't have any control over the columns. Can anyone please show me how to show RadDateTimePicker in RadGridView column when AutoGenerateColumns is True?
My XAML code for RadGridView is as below:
<telerik:RadGridView Grid.Row="1" AutoGenerateColumns="True" ItemsSource="{Binding ManualDataTable}" IsReadOnly="False" CanUserDeleteRows="True" Name="radGridViewManualData" ShowInsertRow="True" />
Any help will be highly appreciated.
Regards,
Moon

I am trying to set the row height of the RadGridView element to fill the whole space of the grid instead of showing blank space when the number of rows is less than the height of the grid, the problem is I couldn't find a simple way to do this without many complications and performance issues using different events to set the RowHeight property when the size is changed for the grid. How to achieve this?

Hi everyone,
I'm using the OpenStreetMapProvider for a long time now, but since this monday I have a problem. Instead of the real map tiles see the the pictures you can see in the attached file. I don't understand whats wrong here. I'm not using MapQuest. And Openstreetmap is still free to use.
Can someone tell me how to solve this, so I can have my map back?
Best Regards
Erich

Is there any way to delete a custom list style?
These commands seems not working and will create some null reference exception on next opening of manage styles dialog.
document.StyleRepository.Remove(listStyle.StyleLink);
document.ListManager.UnRegisterListStyle(numListStyle);
document.ListManager.UnRegisterListStyle(listStyle);

Hello,
I have a RadRibbonGallery bound to a collection of business objects in my view model. When I select an item in the gallery, an action is triggered and after that action, the item in the RibbonGallery should be deselected, so the user can select the same item again.
I tried to implement this by two-way binding the SelectedItem property of the RibbonGallery and in the property setter, set the value to null.
However, selecting works, but setting the SelectedItem to null does not deselect the item.
Is there another way to deselect? I also tried binding to both SelectedItem and SelectedIndex and set the SelectedIndex to -1, but it does also not deselect.
Thanks in advance,
Michael

How do I select a spesific row from my ViewModel (we're using mvvm pattern and no codebehind)? I have tried several approaches with no luck. Tried to set SelectedItem, tried to set CurrentItem, IsSynchronizedWithCurrentItem true/false. Nothing seems to help. Debugging the ViewModel shows that the row is selected, but the Gui is not updated.

When we print any large (10-500 pages) document using WPF PdfViewer the UI becomes unresponsive. For the document with 100 pages it might take minutes. Are there any solutions for PdfViewer that improve User Experience printing large documents? To be more specific, is there a way to:
Show the progress bar with number of pages completed and left or % done with "Cancel" printing job button
OR
any other solution that would help to implement asynchronous printing?
