We would like to disable the Undo feature of the underlying TextBox in the RadNumericUpDown control.

It interferes with our global Ctrl+Z undo command when the RadNumericUpDown is keyboard focused.

Thanks.

I have problem with using DragAndDropManager for Telerik version 2012.1.326.40. Recently I find out that one of my old projects has problem with drag end drop with some list boxes. It was using RadDragAndDropManager to handle drag and drop. So I switched to DragAndDropManager. However in 2012.1.326 version of controls there is no DragDropPayloadManager. All examples are using this class to pass data so my question is can I implement DragAndDropManager in this version of controls and how to replace DragDropPayloadManager.

Hello. I try to set ChartAnnotationLabelDefinition.Template in the way where the label of annotation has red color. But I havn't got the required result yet. I wrote the following XAML markup:

But when I run my application and navigate to the View where charts are displayed then I see only annotation without label (please see 'AnnotationWithoutLabels.PNG' file attached). When I comment the following part of XAML markup

then I see annotation with black colored label (please see 'AnnotationWithBlackColoredLabel.PNG' file attached). How do I get a bright red color for the annotation label?

If you find yourself binding your RadGridView to objects that are dynamically generated by Castle's DictionaryAdapter.

You might be surprised by the expressions that are generated by the ExpressionEditor involve a mysterious CastleDictionaryAdapterType like 

when you were expecting it to be:

where IDataRecord is the interface your run-time instances are generated from by DictionaryAdapter

Despite the fact that CastleDictionaryAdapterType implements your IDataRecord (and a bunch of other things) you won't be able to directly cast between them as your FilterDescriptor requires

The solution is to re-write the expression that ExpressionEditor.Expression property gives you. Here's a simple expression visitor that does that:

You can use it like this (I've modified the ExpressionEditor filtering RadGridView Telerik sample) 

What is needed here is to provide a way to signal to the ExpressionEditor the specific type/interface to use, as opposed to letting the control figure it out from its Item property.

I have a read-only List<string> property in my business object.

How do I make it show up in the property grid. Do I need to create a custom editor?

Hi! I have a project with a RadGrid table showing information. I have this snippet of code inside it:

<telerik:GridCalculatedColumn DataFields="Stake,TotalGames" Expression="iif({1} = 0, 0, {0}/{1})"
FilterControlWidth="40px" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right"
UniqueName="AvgBet" DataFormatString="{0:N2}" HeaderText="Avg Bet (Real)" DataType="System.Decimal"
Aggregate="Avg" FooterStyle-HorizontalAlign="Right" />

Now, this works with English and Chinese locale settings. However, when we set the locale to ES, the formatting changes (from 0.00 to 0,00), and we believe that the problem is coming from the Expression in the code. We think that it might be that the values were interpreted as string? It works with English and Chinese locale (maybe because of the standard number decimal formatting).

We have tried these approaches but to no avail:

1. On binding data (OnNeedDataSource), we modify the locale like this:

 if (dtable.Locale.ToString().Substring(0,2) == "es")
      {
        System.Globalization.CultureInfo myCultureInfo = new System.Globalization.CultureInfo("en-gb");
        dtable.Locale = myCultureInfo;
      }

However, this still shows the same problem. 

2. We tried this as well (IsLocalizationLanguageRespected set to true or false): 

<telerik:RadGrid ID="grdSessions" runat="server" GridLines="None" AllowFilteringByColumn="True"
          PageSize="50" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" 
          GroupHeaderItemStyle-Font-Bold="true" GroupHeaderItemStyle-ForeColor="Black"
          EnableHeaderContextMenu="True" OnNeedDataSource="grdSessions_NeedDataSource"
          Width="98%" ShowFooter="true" IsLocalizationLanguageRespected="false">

We are not sure how to approach this one next. Can you give me suggestions on how to proceed? 

Thank you!

Hello

Do you provide source code for Outlook-Inspired Application?

Thank you

I'm trying to load a collection (which is an attribute of an object) into a RadComboBox (instead of just having the id / ToString inside a textbox).

I got this working so far with a datatemplate which I apply inside the AutoGeneratingPropertyDefinition Handler.

DataTemplate dt = (DataTemplate)this.FindResource("TemplateComboBoxTemplate");                 
e.PropertyDefinition.EditorTemplate = dt;

The template looks like the following:
<DataTemplate x:Key="TemplateComboBoxTemplate">     
    <telerik:RadComboBox ItemsSource="{Binding Source={StaticResource TemplateComboBoxSource}, Path=Templates}"
                         Margin="0">
        <telerik:RadComboBox.ItemTemplate>
            <DataTemplate>           
                <TextBlock Text="{Binding Title}" />         
            </DataTemplate>       
        </telerik:RadComboBox.ItemTemplate>     
    </telerik:RadComboBox>   
</DataTemplate>


As I said, the above works great, except that I have no idea how to set up a two way binding 

so that the RadComboBox actually reflects the property.
