Is there a way to use the masked input to force proper email address formatting?
something along the lines of Mask="a25\@a25.LLL" or even better Mask="A3a25\@A3a25.L3"
I'd like it so that when the user types an '@' it skips the rest of the email prefix characters.
Same thing when they type the '.'
Can anyone think of a simple way to do this where I don't have to check the characters pressed in the code behind. That just seems like it wouldn't be a very cost efficient trasaction.

Is there a way to define the field layout (Grid.Row, Grid.Column) when handling the AutoGeneratingField Event in C# ?
When Auto Generating the DataForm fields, it seems as though one cannot define the field sequence or position (only one column of fields is generated).

I have created a custom control by deriving a class from the RadMaskedNumericInput control. It works fine until I create a resource style for it. Once the style exists, the control is no longer visible when running the app. When I tab, I can still give it focus, but it is not visible. It is visible when on a page in Visual Studio designer. I am working in WPF. The problem does not occur when wrapping the RadDatePicker.
Here is the derived class:
Here is the derived class:
public class ccNumericTextBox : RadMaskedNumericInput
{
public ccNumericTextBox()
{
}
public override void EndInit()
{
base.EndInit();
}
protected override void OnGotKeyboardFocus(KeyboardFocusChangedEventArgs e)
{
this.SelectAll();
base.OnGotKeyboardFocus(e);
}
}
Here is the XAML:
<cc:ccNumericTextBox x:Name="txtDuration" Padding="2" Mask="#3.1" Height="22" Value="{Binding Path=Hours, Mode=TwoWay}"/>
Here is the Style:
<Style TargetType="{x:Type cc:ccNumericTextBox}">
<Setter Property="Margin" Value="3,3,3,3"/>
</Style>

Hi,
I was stuck at a point where I need to assign a shortcut key which is stored in the database respective to a menu.
When I fetch the data the for the menu, I fetch all the details related to it, in a hierarchical manner and bind it to RadMenu DataSource.
Now my requirement is to assign the shortcut key to each RadMenuItem in the RadMenu, for this I thought of creating a CustomCommand using RoutedCommand, CommandBinding and KeyGesture. With this will create a MenuRoutedCommand and thus create a Command that will be assigned to each RadMenuItems command property.
But when i found the RadMenu items in loaded event, those items are not the RadMenuItem but the collection of Hierarchical object used to create the item. So, not able to assign Command as I was unable to get the RadMenuItem.
Please let me know how to assign Command in HierarchicalData source.
Or If there is anyother approach to assign shortcut keys dynamically to the RadMenuItem.
Please reply to it as soon as possible.
Thanks.

I am getting the following sorting error in several grids with different bindings when trying to sort. The data shows up correctly but I get an error when I try to sort:
'SystemFindingSystemModifierTypeEntityCollection' type does not have property named 'SystemModifierType_.Name', so cannot sort data collection.
I am using LLBLGen as my ORM and here is an example of a GridViewDataColumn I am using:
'SystemFindingSystemModifierTypeEntityCollection' type does not have property named 'SystemModifierType_.Name', so cannot sort data collection.
I am using LLBLGen as my ORM and here is an example of a GridViewDataColumn I am using:
<
telerik:GridViewDataColumn Header="Modifier Type" DataType="{x:Type System:String}" Width="*" DataMemberBinding="{Binding SystemModifierType_.Name}" />

Can someone provide any example to use ExpressionColumn with MVVM?
I have a GridView Itemsource binded to a collection of clients. Only on the grid i need to show a column to calculate 2 values, but i only find examples puting business logic on view, nothing using mvvm.

Hello Telerik,
We use a ResourceFIle for all displayed text in our application in order to support Globalization. This works great for the GridViewDataColumn.Header unless it is in a child GridView.
In the example below, we were forced to use a custom header in in the RowDetailsTemplate in order for the Header to Display correctly. If we set the Header property in _gridDetails like in _gridPing it does not work. There were no binding errors, but the Header text was the displaying the binding property name, not the ResourceFile property value.
Is this a known issue? I would like to use the simpler syntax if possible.
Thank you,
-Mark

Do the Telerik controls work with Visual State Manager? I am using 2010.1.309.35 right now, and specifically I am working on the GridViewRow. I notice that the template doesn't automatically show states in Blend, but didn't expect it to either. But it appears that I cannot create these states either like I can on standard MS WPF 3.5 controls. For example, I created a VisualStateGroup named CommonStates and added the states Normal and MouseOver. I really prefer working with VSM as opposed to triggers and wondered if someone from Telerik could address VSM support in Telerik controls.
Thanks,
David

Hi,
How would you handle the following issue?
Setup
I have a DocumentHost control which contains 2 RadPanes (RadPane1 and RadPane2). Each RadPane contains 2 textboxes (Textbox1 and Textbox2). I have subscribed to the GotFocus and LostFocus on each RadPane.
Steps
1. I float RadPane2 and subscribe to the GotFocus and LostFocus of the ToolWindow using the PaneStateChange event.
2. I leave RadPane1 in the DocumentHost.
3. I click on RadPane1 Textbox1 and the RadPane1 GotFocus is fired.
4. I click on RadPane2 Textbox1 and the RadPane2 and ToolWindow GotFocus is fired.
5. I click on RadPane1 Textbox1 and no GotFocus is fired for RadPane1.
6. I click on RadPane2 Textbox1 and no GotFocus is fired for RadPane2.
7. If I click on RadPane1 Textbox2 GotFocus is fired.
Observation
It seems as though I can have one RadPane in the DocumentHost and one floating ToolWindow which both think they have focus at the same time. Shouldn't I only be able to have one RadPane that has focus as any point in time?
Question
How can I work out which pane has focus regardless of where it is located? Unfortunately the RadDocking control does not have an event like this.
