Hi,

i bind an ObservableCollection to a RadGridView.

TaskGridView.ItemsSource = ItemColleciotn;

xaml:

<telerik:GridViewDataColumn DataMemberBinding="{Binding Mydate, StringFormat=d}" Width="80" Header="{Binding Source={StaticResource Lang}, XPath=GrudDatumHeader/@Header}" x:Name="Beginnlbl" >

Now i want to sort the GridView

<telerik:RadGridView.SortDescriptors>

<telerik:SortDescriptor Member="MyDate" SortDirection="Ascending" />

</telerik:RadGridView.SortDescriptors>

The Problem ist, that the GridViewDataColoumn is a string and the sorting works, but in a wrong way for example:

08.11.2014
09.11.2014
10.10.2014
11.11.2014

The Date 10.10.2014 should be the first one. How can i solve this?

Thanks
Best Regards
rene

BusyIndicator changes back to Office_Black

I have a WPF application. I've set the theme of my RadBusyIndicator to Windows8Touch with the below code in app.xaml using the code below.

<Application.Resources>
<Style TargetType="telerik:RadBusyIndicator" >
<Setter Property="telerik:StyleManager.Theme" Value="Windows8Touch"/>
</Style>
</Application.Resources>

I show the indicator by setting and IsBusy property in my viewmodel. Everything looks and works great until the very end. About 1 second before the indicator goes away (IsBusy=false) the theme turns from Windows8Touch to Office_Black (the swirling orange donut). It should not change!

What could be the problem?

Thanks,
Mark

RadListBox vertical scroll bar

Hi,
I'm using this code in XAML:

<telerik:RadListBox Margin="5" DisplayMemberPath="Description" Name="lstResults" ScrollViewer.VerticalScrollBarVisibility="Visible" ScrollViewer.CanContentScroll="True">

This ListBox is filled at runtime after pressing a search button.
The vertical scrollbar never shows.
In the search button event, after setting the ItemsSource property, I also put

ScrollViewer.SetVerticalScrollBarVisibility(Me.lstResults, ScrollBarVisibility.Visible)

with no success.

Can you help me?

Selecting multiple groups of items within the RadGridView list

Hi,

Is there a way to select multiple groups of items in the WPF RadGridView list.
For now I am able to use Shift + Click to select the start and end of the group I want to select.
I want to repeat this action multiple times to select multiple groups of such items.
Is there a way to achieve this functionality?

I am using Telerik WPF toolkit version 2013.1.331.45.

Thanks,
Manoj.C

Filtering Strings with IsEmpty and IsNull

To most users a null string and an empty string is the same thing. How can I reflect that in the grid filters? Right now I have null values that aren't filtered when they select IsEmpty and vice versa.

Is there a nice way to have all my string columns have a filter IsNullOrWhitespace ?

Is this editor support Microsoft Word Shape and Smart Art?

We used the DocumentFormatProviderManager class to do the importation of DOCX. However, as I checked the code via Resharper disassembly there was no implementation for Shape importer. I believe it was not supported in version.

Please verify.

RadGridViewCommands.MoveNext doesn't work

Hi,

I've searched forum for information how to manipulate keyboard navigation behavior of the grid (RadGridView), and I've found a few posts. The best is here http://docs.telerik.com/devtools/silverlight/controls/radgridview/commands/KeyboardCommandProvider and http://blogs.telerik.com/xamlteam/posts/10-06-30/how---to-change-the-default-keyboard-behavior-in-radgridview-for-silverlight-wpf.aspx but focus after action MoveNext doesn't work. Focus is moved to nothing and when I click Tab key to check where is the focus it's moving to the first control (focus-able) on the screen. This works only for MoveDown but it's direction I'm not interested in. Is there some property that should be set?
