i am developing a docking application using Prism mvvm, which consist of 2 modules ModuleA and ModuleB, both modules are using Telerik RadDocking control. For using docking control with prism, I followed some code from code library. which infact register DockingRegionAdapter as Mapping for RadDocking. DockingRegionAdapter overrides CreateRegion, where new region is created with Behaviour DockActivationRegionBehavior, as follows

Problem: When I switch from Module A to Module B, it raises Exception at line 5 with following error message.

An exception of type 'System.InvalidOperationException' occurred in Microsoft.Practices.Prism.Composition.dll but was not handled in user code
Additional information: The Region property cannot be set after Attach method has been called.

My Code: DockingWithPrism.zip

Hi, 

I am using RadCartesian Bargraph(Cluster) to visualize data. I have a model class with certain properties which holds the value for CategoricalDataPoint of each bar in cluster.

however, when I bind this CategoricalDataPoint value to the property of model class. I get error A 'Binding' cannot be set on the 'Value' property of type telerik:CategoricalDataPoint.  This is my xaml

 <telerik:BarSeries CombineMode="Cluster">
                            <telerik:BarSeries.DataPoints>
                                <telerik:CategoricalDataPoint Category="today" Value="{Binding Propertyxxx}"/>
                                
                                <telerik:CategoricalDataPoint Category="day-1" Value="{Binding Propertyyyy}"/>
                                
                            </telerik:BarSeries.DataPoints>

Please help me how to solve this issue as soon as possible.

I'm trying to programmatically achieve filtering out of empty strings in a column.

 I.e. I wish to automatically set up the second grid in my attached image.

 I've tried:

            suffixFilter.DistinctFilter.RemoveDistinctValue("");
            suffixFilter.DistinctFilter.RemoveDistinctValue(".");
            suffixFilter.DistinctFilter.RemoveDistinctValue(string.Empty);

and also:

            suffixFilter.FieldFilter.Filter1.Operator = FilterOperator.Contains;
            suffixFilter.FieldFilter.Filter1.Value = ".";

but these only achieve the first grid. Please help!

Many thanks,

Hallo,

I'd like to ask you what is wrong in my scenario. I have tab control with more tabs. In every tab si RadDiagram. When i try copy paste in one diagram everyhing is fine. When i copy item from one diagram to another i have some trouble with style selector. In first case(copy and paste in one diagram) input paramter of the SelectStyle method is type MindMapNode(my custom class represents diagram node. it inherit NodeViewModelBase). But when i copy paste from one diagram to another input parameter of SelectStyle method is Shape  so my logic of selecting style can't handle it. Could you be so kind and give me some advice how to fix this ? 

Thank you very much.

Greetings

Hi,

We are using ExportToXlxs to export data from RadGridView in our application. Wondering, how to write additional data to the stream like below using the ElementExportingToDocument event. Thanks!

Hello,

I'm working on a WPF application. When the client encounters an exception, we log the exception into a log file, which also includes the exception stack trace.

Now, I'm trying to solve the following exception (I'm not sure how to reproduce the problem, cause as I've mentioned, it comes from a log, and I don't know which screen of the WPF app caused the issue):
