Rounded Corner on RadComboBox

[Brett]

I want to round the corners on a RadComboBox, but I don't want to go through and edit the template for it. Is there way to do that without going through the hassle of doing that? Potentially just using a setter property or something to do it on the xaml side?

thanks.

Hi Brett,

In order to achieve the desired appearance you could set the CornerRadius property of the ButtonChrome situated inside the NonEditableComboBox Template to the desired value. In code behind you could do that by hooking to the Loaded event with the following implementation:

private void DiskChoices_Loaded(object sender, RoutedEventArgs e)
{
    var radComboBox = sender as RadComboBox;

    var buttonChrome = radComboBox.Template.FindName("ButtonChrome",radComboBox) as ButtonChrome;
    buttonChrome.CornerRadius = new CornerRadius(10, 10, 10, 10);
}

Hopes this helps.

Your answer did work, but how can I move that into a behavior in XAML code?

Hello Brett,

You could create an attached property for setting the desired CornderRadius in order to extend the functionality of RadComboBox - thus you would be able to move that setting of the CornerRadius in Xaml code. 

We have created a sample project that demonstrates that approach - please, check it.

We hope this will help you.
