I have a few questions I need answered:

1. How do I turn off the grouping feature?

2. When the data in a RadGridView is being exported in text format, is there a way that I can change the format of the data output?  Meaning, I don't want the text surrounded by double quotes and I want each column to occupy a certain number of columns.

Thanks

Tony

P.S. I deleted the other questions that were originally in this post as I don't need them answered any more.  These two, though, I still need answers to.

Thanks

Hi, I am very new to Telerik, and I am trying to get an old half finished project that uses Telerik working in VS2010. It builds fine but when I try to debug I get an XamlParseException exception, here is the details:

Is there any COMPLETE example to create a custom theme based on Windows7 theme? I tried a lot of ways to do my own reading this forum but no one supports Q1 2012 version; not even WPF. Thank you!

Hello,

When I display a RadCalendar control in a WPF application with the property IsEnabled=false, and then change the property to true. The number days remain grey and when I move the mouse over them they change it Forecolor to black.

<telerik:RadCalendar Grid.Row="1" Grid.Column="0"  Grid.ColumnSpan="2" Grid.RowSpan="2" MinHeight="620" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
		Columns="4" Rows="3" SelectionMode="Multiple" Name="calMain" IsTodayHighlighted="False" AreWeekNumbersVisible="False"
		FontFamily="Segoe UI" HeaderVisibility="Hidden" ViewsHeaderVisibility="Visible"
		IsEnabled="False" Background="White" Foreground="Black" />

private void btnEnabled_Click(object sender, RoutedEventArgs e)
{            
    calMain.IsEnabled = true;
}

How can I avoid this behaviour?

Regards,
Gerardo.

I'm wondering about the reason why RadPane and RadDocumentPane fire the IsVisibleChanged and Unloaded events when I'm just dragging the Pane to an other place on the screen (in my case out of my MainWindow)?

IsVisibleChanged might be plausible, because the Pane becomes invisible for the split of a second, but Unloaded is not plausible, because the the Pane still exists.

So to which event do I have to listen if I want to react on the user clicking on the small cross on the pane to close it, if  IsVisibleChanged and Unloaded happen also when the user is only dragging the Pane?

Hey,

Unfortunately I have a problem in the sort, filter and group functions in the following case:

Class A
{
string AName;
}
Class B : Class A
{
string BName;
}

Class C

{             

A baseClass;

}

 

The item source is ObservableCollection<C>
I am creating in code behind new GridViewDataColum.

If the binding is
1. " baseClass.AName" =>Everything works.
2. " baseClass.BName " =>The grid view rows are ok.All the data is shown in the correct cells,

But the Filter,Group,Sorting is not working.

 

 What can I do?

I have two RadPanes that I wish to persist only the IsPinned property of.  I wish nothing else to be persisted, how would I code this?

The two RadPanes are the only UIElements with a StorageID and their SerializationOptions are set as


When I call Load after persisting, the entire RadDock is missing.

Thank you
Scott Lee

We are using Q1 2011  SP1 telerik version. 
There is a radwatermark textbox used in a radgridview. The loaded event is not firing on double clicking the text box in the gridview.
The same functionality works with Telerik version 2010 Q3.
We are not planning to use latest 2012 telerik version due to some animation issues for our application.
Please suggest any quick solution at the earliest.

I am trying to implement a chartview with a line series. The x axis has values in miliseconds. I feel the features of the linear axis suites me more then the DateTimeCategoricalAxis but I can't seem to get it to work with linear axis in both horizontal and vertical directions. Doesn't this work? And if it does, how would I do thìs? Is there any example showing this?    

Hi

i am creating readonly ranges using the InsertReadOnlyRange method.
This works well most of the times.
However I get a NullReferenceException deeply from the tk-lib code
with the following stacktrace:

    
the line raising the exception goes like:


"Parent" is null here.
I noticed that the "null-ness" and the exception only occur if the span is inserted using InsertInline:



so my wish to the telerik developpers is to fix this line of code.
There are circumstances where a spanbox has no Parent layoutbox.
(E.g. when appending it with InsertInline). So you can't use it to get its previous sibling.
If you anaylze the stack trace and the surrounding code of "GetCaretInline"
it's fully OK to null check the Parent property and in this case simply return
the span associated to the layoutbox "currentSpanBox".
