I have an MVVM WPF app with a RadTreeListView that is populated via a Generic List<T> using nested sets from a database. Only the first column of the TreeListView gets populated. What class would be appropriate to replace the generic List so that I can pass multiple columns of data to the TreeListView?

I posted this same question, with code, on the WPF Forum of MSDN and was told that my existing approach with List<T> should work with the TreeListView.  I was also told that since the question involves a third party control, i.e., Telerik, I should move the question to the Telerik forum.

My xaml showing the data binding: The "Description" and "Imported Equipment Type" columns do not get populated.

My code for my data class is as follows. My xaml ItemSource is bound to Children:

The constructor for my navigator ViewModel is:
And the service that fills the list:

All of this works except that the tree is populated only in the "Tag" column. "Description" and "Imported Equipment Type" are blank.

Hi,

we use in our application the Telerik OfficeBlue theme, does anybody know how to to get the OfficeBlue theme for the GridSplitter and RadExpander component???

Both of these components are white (too many shade of white in my RadWindow) actually and the splitter doesn't have the "....." indicator so for a user it's a little bit difficult to find where he havr to achor the splitter to change his window disposition.

Thank's

Hi,

we use VS2008 and Telerik V2012.2.912.35 and we have a docking application with 4 pans and when we start to undock a pan, the pan we start to undock start shaking....

When the pan is is floating and we start to dock it, no problem. If we start to undock it again, the pan start shaking again.

One thing to consider, in my XAML is have such kind of binding for each RadPane:
IsHidden="{Binding ElementName=Me, Path=PaneVisibility}

This binding is to hide each RadPanel when I change the Visibility of my main window.

Any thought???

Thank's

Hi there,

We have an application that uses the RadRichTextBox multiple times in the same dialog, one for each row of data. Each RadRichTextBox makes use of spellchecking. What we've found is that with spellchecking enabled, the memory is not released when the dialog is closed, while it is mostly reclaimed when spellchecking is disabled.

I might be wrong, but what I've figured from using ANTS Memory Profiler is that it seems to be attributed to the DataChanged event on the SpellChecker; the event doesn't seem to be unsetting when the host object should be disposed. This appears to be causing all related controls to remain in memory.

As this control is heavily used in our app, the problems quickly add up, and we've seen OutOfMemoryExceptions occur. The attached file shows the ANTS results. Notice the memory usage between the blue and red markers at the top - the rise in memory usage is attributed to repeatedly opening and closing the same item.

Any assistance with this would be greatly appreciated.

Hi,  
      I have found an issue with find and replece functionality. Actually while find and replace process the text box does not copy the format and styles while replacing text in Replaceall command. It does work with replace commond but with ReplaceAll its not. Can any one suggest me some thing in this regard thanks.

Hello, I have a WCF Web Service, that makes a SQL query  to a data base and returns  a DataSet with the data.
In my WPF browser app I have a gridView and it's ItemsSource is the DataSet that the service returns, at first I got this code:


It works fine, and does what it's supposed to do, the call to the service takes some moments, so I decided to change the cursor to a clock, but once I had it all working I like to change it for a busy indicator, so I added it to my code:


a
It's the same code, and it should work, but when I try to call the service:

I get an exception:
An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in Unknown Module.
Additional information: Index was out of range. Must be non-negative and less than the size of the collection.
If I remove the busy indicator and the background worker it works fine and I can't understand what's happening, I have no clue,
I hope somebody can help me.
Thanks!!

I create an RadChart in the code and i want to export it to a file "png".
I disabled animations!

Now the point is in PieSeriesDefinition & LineSeriesDefinition this is correctly working, but in the BarSeriesDefinition & StackedBarDefinition is painting everything except of the bars!

See screenshots..

Any clue why this could occur? I think the BarSeries has some additional Animations?

when i use the chart,and use chart.Series[0].ItemsSource = tempDrw ( here the tempDW is a double type array; to draw the line like the attachment.

I have a scatter series where all the values are aligned at Y == 1.0. The RadChart is inside a grid with a gridsplitter controlling the space available for the RadChart. Now, if I scale the view vertically, sometimes values are displayed incorrectly (see red triangles in the example screenshots below). This issue doesn't appear always, but often enough to be a serious problem for us. If the problem occurs, the only way to fix it is to resize the RadChart again, horizontally (always fixes the problem) or vertically (usually fixes the problem, sometimes the problem reappears).

We are not changing the data bindings or anything like that, we are simply rescaling the grid view with the gridsplitter. With the data in the screenshots it is very easy to see that triangles were rendered at incorrect Y-values. But we have other visualizations where the scatter data is not aligned to a single Y axis value and we can't afford the items to be displayed at incorrect values!

I'm limited to version Q2 2011, what can we do to fix this?

After scaling vertically:


And after additional scaling:


Here's an example of the blue and red scatter series, both using exactly the same data binding:


Obviously, this is not acceptable.

We are currently using the RadPropertyGrid control to display information for different types of Business Objects. We're also using the Command pattern to support undo / redo functionality for certain actions (adding a new Business Object, removing a Business Object, etc.).

What we would like to be able to do is somehow hook our RadPropertyGrid into our Undo/Redo Service. We have considered listening to the PropertyChanged event of the object that is currently being display through the RadPropertyGrid, but wanted to see if anyone else had tackled this problem before, or could point us in the correct direction.

Any help would be greatly appreciated.

Thanks,
