Hello. I'm trying to figure out the proper way to provide editing for a collection of name/type/value things. I was hoping to use DynamicObject, and expose dynamic properties for the properties to be edited. DynamicObject however, as far as I can tell, has no real way to expose more than a member name to consumers (such as RadPropertyGrid.) So, I don't know how to expose the TYPE of the propert to RadPropertyGrid.
What's the best way to go about this? Is DynamicObject suitable?

I have a situation where I'm setting the RadPropertyGrid's Item to an ExpandoObject instance whose properties have been defined at run-time. I'm listening for the PropertyChanged event of the ExpandoObject to tell when a property has been updated.
I'm using the AutoGeneratingPropertyDefinition event to catch properties with specific names and assign an EditorDataTemplate that uses a RadNumericUpDown control. The problem is that the property value (let's just use the name "Prop1") is set by a nullable double, so sometimes Prop1 has a value, and sometimes its null. If Prop1 has a numeric value everything works great with the property editor, and I can change the field for Prop1 and it will change its corresponding value in the ExpandoObject perfectly.
However if Prop1 is set to null, its field shows up in the PropertyGrid but when I change the value I don't get any PropertyChanged event from the ExpandoObject. The event fires if I set a value to Prop1 in code-behind, but not if I try to change it from the PropertyGrid. This leads me to believe there is some sort of binding issue with the property grid and ExpandoObject properties with null values.
Any suggestions?

Hi,
I use RadGridView in my project...
when i change the value at some row (only happen at textbox, when i change value at checkbox/combobox it doesn't happen) and then try to sort the column ascending or descending it crashes.
It only happens when i set AutoGenerateColumns to false (which is always the case in our application..)
To enable sorting, I set DataMemberBinding of each column.
The error I get is:
"The runtime has encountered a fatal error. The address of the error was at 0x5b7d157d, on thread 0x430. The error code is 0x80131623. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code."
The code I use:
<telerik:RadGridView AutoGenerateColumns="False" ItemsSource="{Binding MyArray}">
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}">
<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<AdornerDecorator>
<TextBox Text="{Binding Name}" />
</AdornerDecorator>
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>
</telerik:RadGridView.Columns>
</telerik:RadGridView>

Hello,
i am trying to use DataPager to display the count of rows in GridView, which are filtered or grouped in the GridView.
Then i have the Binding of Items with GridView.
<telerik:RadDataPager
Grid.Row="1"
PageSize="25"
Source="{Binding Items, FallbackValue={x:Null}, ElementName=GridView}"/>My problem is that, if i use Groupe function of GridView, i will see the number of groups insteads of the number of shown rows of GridView in DataPager.
Has somebody solved this problem? Thanks a lot!

We need to be able to enable or disable a DataPager associated with a GridView when the window loads (some users want it and other don't). I have tried setting the visibility to collapsed, setting IsEnabled to false and setting Source to null in the window constructor. None of these work. The pager isn't visible but the grid only shows the first page of data. The grid's ItemsSource is bound to an ObservableCollection and is populated in the Window_Loaded event. Here is the relevant xaml:
</telerik:RadGridView> <telerik:RadDataPager x:Name="DpEvents" Grid.Row="2" Source="{Binding Items, ElementName=grdEvent}" PageSize="18" DisplayMode="All" AutoEllipsisMode="Both" NumericButtonCount="10" IsTotalItemCountFixed="True" />

Hi,
I'm migrating from RadMaskedTextBox to the new mask controls and encountered the following problem with MaskedDateTimeInput.
Up until now I used to set the "Text" property of the control, because my data structure holds the value as string with the correct format.
When I try setting the "Text" property of MaskedDateTimeInput via code to a certain date string, it doesn't affect the "Value" property.
When I click on the control it changes the text back to the current date.
I know I can use the value property but that requires me to convert my text value into DateTime and I don't want to do that if it can be done automatically via the control.
Please advice

Hello,
in the new features of the Q3 2015 version, it is that we can use IconSources to change the icons used for a RadRichTextBox UI.
Unfortunately, the documentation is very poor: http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/how-to/switching-icons-at-runtime
1. Where do I need to put this XAML code?
2. Where do I specify the set of icons to use?
And most important:
3. How can I define my own icons for RadRichTextBox?
Thanks in advance
