Greetings,
 
I keep getting the "theming resource not found" exception when trying to clear the current data series of a chart component, even though i patched up the Q3 2011 version with SP1. The code that throws the exception is the following:


and the stack-trace is as follows: 

Theming: Required resource not found. Please, make sure you referenced all necessary themes and resources.

Any ideas?

I have set the  IsLoadOnDemandEnabled  to True at the Tree level and it makes all the node's images to show like, it has children nodes to be loaded. 

In Reality, not all of the nodes are Expandable. 

Lets for example say, I need to expand first level to dynamically load the next level. In the next level of nodes, some of them may have children nodes to be loaded when you click on them dynamically and some of the nodes are already the leaf nodes, meaning they are the last node and they don't have any child node. For these leaf nodes, I don't want the Image of the node to show as Expandable. 

Only the nodes that have children nodes to be loaded need to have the Expandable icon. 

How do I handle this situation. Its misleading when you show the Expandable icon or + icon for all the nodes irrespective of whether they are the last node or not. 

Please let me know if I am making sense. 

For our application we would like to save alot of the customers settings.
One of these is the width of columns and the order. So I have done the following
  Width="{Binding ProjectPartsOverview_Column_Width_Delete, Mode=TwoWay, Source={x:Static properties:Settings.Default}}"

But that width is not being loaded from the settings or updated.
Also I have no clue how to save the order of the columns

Hi @ all,

i'm looking for a source or tutorial for Drop a RadCarouseltem to a Rad GridView. I don't want to delete the Item from the Craousel, but i want to add the selecteditem to a DataGrid.

Thank's for helping me.

Our users use - when sending letters - envelopes with a window where you can read name and address.
To help them to write the name and address on the right place I can show a rectangle in the background of the RadTextBox.
The question is: what is the best way to skrew this feature/style on and off?
Or... do you know a better way to show/hide such a rectangle?

<telerik:RadRichTextBox x:Name="editor" AllowDrop="True" Drop="EditorDrop" ShowComments="False" FontFamily="Calibri" FontSize="11">

Hi

In quite a few places i am using converters with the RadGridView to convert the values in the domain model to values presented in the users. I have attached an example where a column is bound to an enum which is converted to a string by a IValueConverter (by using a ressource file for easy i18n)

As there seems to be no support for the converter notion directly in the RadGridView i have done this in the following way:


However when i then group on these columns, the value is of course not converted. I have attached a screenshot showing this.
I could probably just define a custom group header template. But the only thing i want is to get the value passed through my converter. 

Is there an easy way to acheive this? If using a custom group header tempalte, how would i do this so it looks like the default group headers - but just with the value from the columns converted? 

Anybody can help me, i want choose default value when i search in text column header.

Example:

When i type anything into text column header and choose the filter, it will show " No filter, StartWith, Endwiths, Contains..." , now i want this default value  is "Contains".

Thank more :)

I'm using an HierarchicalDataTemplate and the FullPath is always the type of the object in the itemssource collection. Is there a way to set it to a specific property of the bound items?  My understanding is that it was supposed to be the displayed text.

<HierarchicalDataTemplate DataType="{x:Type local:Employee}" >

<TextBlock Text="{Binding Path=Name}"></TextBlock>

</HierarchicalDataTemplate>

My Employee object has a list of employees and everything is displayed correctly.  However the FullPath of the SelectedContainer is always MyNamespace.Employee.I need the FullPath to be the Text of the node or need the ability to assign a property to be used by the FullPath for example, EmployeeId or something.
Thanks,

 

 

 

Is it possible to add extra lines (e.g. a regression line) to the chart?
