    Resolved [RESOLVED] Rounded Combobox

    Why does the dropdown arrow disappears when I try to use the following code? Is there any other method which I can round out the corners of the combobox? Thanks!

    Code:
    <ControlTemplate x:Key="ComboBoxTemplate" TargetType="{x:Type ComboBox}">
        <Grid>
            <Border x:Name="border" Background="White" BorderBrush="#FFFFC934" BorderThickness="2" CornerRadius="10,10,10,10" Width="Auto" Height="Auto">
            </Border>
        </Grid>
    </ControlTemplate>
    Regards,

    Re: Rounded Combobox

    I'm no expert on control templates but I think when you define a control template you are defining the entire control. So the combobox that you apply that template to will be JUST that border that you have defined and nothing else - hence the drop down arrow disappearing.
    From what I remember, you can assign special names to "parts" of your control template and then WPF will treat them in the same way as their standard control counterpart. For example the little dropdown arrow might be named PART_DropDown in the standard combobox control template, so if you define something in your template and name it that same name then WPF will make it do the same things as the normal one would do (but without the same visual effects obviously as thats for you to define). I'm not sure whether the little arrow in a combobox is actually a separate part though, but you can find out by using Expression Blend to edit a copy of the combobox control template and examining the 'internals' of it.

    Sorry if any of the above is not 100&#37; correct but its been a while since I did anything like that. Have a look on the web for Control Template tutorials

    Re: Rounded Combobox

    Upon searching and trial and error I was able to get the look that I want. It occured to me that a ComboBox is composed of various controls and I needed to modify the borders of those controls to suit my needs. Attached is a sample project that has the modified control template if anyone is interested.

    Thumbs up Re: [RESOLVED] Rounded Combobox

    Great example! I have one question: how is the gradient around the combobox controlled? I've set almost every color to #FFF and nothing seems to change it. Thanks for any help you can offer.
