Hi I have just upgraded to SP1, removed the old references from my project and added the new ones but I now get the following unhandled exception when I open my main.xaml in VS2008


Any advice?

Thanks in advance,
Kevin Preston.

Is there a way to use a Delegate on the TabControl?

Currently, I have (in XAML):
  SelectionChanged="radTabControl1_SelectionChanged"

in the ViewModel:

     And my otherwise empty .xaml.cs file:

 
It works, but aren't we supposed to be able to do things without the code-behind?

Or, is there a better way to bind to the SelectedIndex ?

I have a panel bar and I am using the hierarchialdatatemplate.  I am also using an MVVM pattern.  My question is how can I set the IsSelected flag on my ViewModel with a setter property and/or trigger on mouse over so that I know which item in the panel bar is currently selected during a context menu action.  I have this working on a listview, but I cannot get it to work with the panelbar.  Any help or example would be greatly appreciated.

Thanks

Using VB in VS2008 with WPF 2009 Q2 Build 724.35.  The problem also showed up using Build 701.
With Build 701, when I added the second group, I got an exception in Telerik.Windows.Data with message
"Specified argument was out of the range of valid values.  Parameter name: position"
With Build 724, the exception is gone, but when grouping by two fields, either run-time or programatically, only the first data record (or the first group) is visible in the grid.  

Here is the code defining the data for the grid: 

 

 

 
Here is one simple variant of the XAML files I have used(autogenerating the columns still has the same problem):

 

 

 

 

 

 

 

Any insight will be greatly appreciated.

Hi ,

I am not able to inherit/override style for telrik:GridViewHeaderCell

 I have Common ResourceDictionary  Style.Xaml , it has

<ResourceDictionary xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">
    <Style TargetType="telerik:GridViewHeaderCell">
        <Setter Property="FontWeight" Value="ExtraLight" />
        <Setter Property="FontStyle" Value="Normal" />
    </Style>
</ResourceDictionary>

Im MyControl.Xaml I have

  <Window.Resources>
        <Style x:Key="CheckBoxHeaderCellStyle"  TargetType="telerik:GridViewHeaderCell">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="telerik:GridViewHeaderCell">
                        <CheckBox HorizontalAlignment="Center" VerticalAlignment="Center"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>
    
In code behind I am using

 var dict = new ResourceDictionary
                           {
                               Source = new Uri("MyApp;component/View/styles.xaml", UriKind.Relative)
                           };
Resources.MergedDictionaries.Add(dict);

I apply style in GridDataColumn as

<telerik:GridViewDataColumn HeaderCellStyle="{StaticResource CheckBoxHeaderCellStyle}"/>

In design mode I can see the checkbox in Grid Header.But It does not show a check box in GridHeader.

I'm setting the grid's datacontext to a dataset with just 100 rows (and 67 columns).

Quite frankly, the gridview's *vertical* scrolling performance sucks - big time. It seems the more columns we have, the worse it gets.  "Deferred" scrolling is not an option (it lags too, BTW).  We need the grid to scroll smoothly as the scroller is dragging down the scrollbar. 

Curiously, horizontal scrolling seems to work just fine, regardless of the number of columns we have in the dataset.

What can we/you do to improve this?

Is there a way to move the position of a tooltip form the default?  Currently, it is displaying bellow the mouse and that is causing it to go beyond the browser window and cuts it off.  I would like it to show above and to the right of the mouse position.  Thanks.

Hi,

I was wondering whether RadControls for WPF support UI Automation...

So I created very simple WPF application: I dragged four Rad controls on a form (RadDatePicker, RadTimePicker, RadMaskedTextBox and RadNumericUpDown). Then I assigned AutomationProperties.AutomationId for each of Rad controls (for RadDatePicker it was "datePicker", for RadTimePicker "timePicker", for RadMaskedTextBox "maskedTextBox" and for RadNumericUpDown "numUpDown").

Now in c# (in Program.cs to be precise) I written code like this (mainWindow is a AutomationElement which represents main application window):

FindFirst method does not find anything, however It should if RadControls for WPF would support UI Automation. Out of four controls I've tested only RadNumericUpDown was found this way.

I've also checked my test application window using UISpy - only RadNumericUpDown had AutomationId properly assigned.

So my question are: 

Am I doing something wrong?

If no, when will RadControls for WPF fully support UI Automation?

RadControls for WPF version used in sample application: 2009.2.701.35

Thanks for help

I use the chart to display some data, but the labels can become very long.
Now I want to use the Default LabelFormat but I do not seem to get it work

I use the following      #LABEL{[a-zA-Z]{0,10}...}

But my string always stays as long as it is. I want the string to be a max of 15 chars and if longer have the tree dots after it
