Click Event

What is the equivalent of the click event in WPF? Similar to what we have for the TabControl version in WinForms

http://www.telerik.com/help/winforms/tab_eventstabselected.html

I have several embedded TabControls / TabItems and need to know when the user clicks on the tab. Not when it got the focus or the selection changed, just the click event.

If such option is not available, is there a way to convert the TabItem header to an hyperlink?

Thanks

Expander is too small of a target

I'm a huge fan of the RadTreeView, which we have recently incorporated into our product. I have only found one thing that I like better about the built-in WPF TreeView, and that is the size of the hotspot associated with the expand/collapse arrow. With the built-in WPF TreeView, you can click not only just on the arrow graphic itself, but pretty much anywhere in the whitespace around that arrow, and the associated node will collapse or expand. With RadTreeView, I have to click precisely on the arrow graphic itself. This is way too small of a target. I very frequently click there trying to expand or collapse a node and miss.

When you click on the arrow to expand or collapse a node, the expander/collapser gets focus, as evidenced by the broken line drawn around it. How about making the entire area of the focus rectangle be the hotspot for collapse/expand?

Thanks,

Eric

Line Chart: Point Lables

Hi,
I have a chart that will have 20 - thousands of records. I need to remove the Point Labels, as they are cluttering my chart.
Is there any way to do this and just leave the point?
Also, is it possible to have a mouse over of the point to display the data?

Thanks,
Chelsey Smith

Strange error message in debug view

Hi all,

While using the RadTab controller, I found the following error message in debug output window

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=DropDownButtonElement'. BindingExpression:Path=IsChecked; DataItem=null; target element is 'DropDownMenu' (Name='DropDownMenuElement'); target property is 'IsOpen' (type 'Boolean')

Please try creating a new project and drag and drop the RadTabControl into the main form and execute. In my case, the VS2010 debug output will display the above error

I am using Q1 2010 SP2 of Rad Ctrl set on VS2010 Ultimate.

This does not hamper the performance of the controller, just the error message in the debug view.

Can any one tell me whether I am doing something wrong or whether this is a bug ?

Thanks ,

Chintana

Regex masked column

I'm working with a grid and need to be able to mask one of the columns with the following format:

XXX-XXXXXX-XXXX-XXXX

An X can be either [0-9] or [A-Z]. Lowercase input could also be allowed, in which case it would be normalized to uppercase before being saved to the data store.

Is there any way to use the built-in masking for this? If not, how would I get started with rolling my own (i.e. what events do I hook when a character is entered, etc.)?

Custom GroupDescriptor Header

Is it possible to have a different DisplayContent that is detached from the member on the GroupDescriptor object for the RadGrid?

Scenario: EscalationID is a guid and is set as the member. However, to make the UI user friendly. I need to change the grouping "Header" to a custom text or a different member.

Binding in BusyContentTemplate

I can get static content to work all day long in the template, but it doesn't seem to pick up my binding.

Any ideas what I'm doing wrong?

Template

<DataTemplate x:Key="busyTemplate">

<StackPanel Orientation="Vertical">

<Label Content="Synchronizing EliteLive.sdf with the remote database."/>

<TextBlock Text="{Binding SyncStatus}" TextWrapping="Wrap"/>

</StackPanel>

</DataTemplate>

BusyIndicator

<telerik:RadBusyIndicator x:Name="busyIndicator" Grid.Row="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"

IsBusy="True"

IsIndeterminate="True"

ProgressValue="{Binding PercentageComplete}"

BusyContentTemplate="{StaticResource busyTemplate}" >
