Ways to heighten the `RadComboBox` `DropDownHeight` featuring `Templates`

One of the challenges I'm facing involves a RadComboBox setup like this:

<telerik:RadComboBox ID="RadComboBoxNames" runat="server" Width="470px" DropDownAutoWidth="Enabled" MaxHeight="363px" Skin="MySkin" EmptyMessage="Select"
                HighlightTemplatedItems="True" DataValueField="ID" DataTextField="ID" OnDataBound="RadComboBoxNames_DataBound" >
                <HeaderTemplate>
                    <table style="width: 250px; text-align: left">
                        <tr>
                            <td style="font-weight: bold; width: 60px;">ID</td>
                            <td style="font-weight: bold; width: 180px;">Name</td>
                        </tr>
                    </table>
                </HeaderTemplate>
                <ItemTemplate>
                    <table style="width: 250px; text-align: left">
                        <tr>
                            <td style="width: 60px;"><%#DataBinder.Eval(Container.DataItem, "ID")%></td>
                            <td style="width: 180px;"><%#DataBinder.Eval(Container.DataItem, "Name")%></td>
                        </tr>
                    </table>
                </ItemTemplate>
            </telerik:RadComboBox>

I notice that despite setting my MaxHeight property to 363px, the actual DropDown height does not reflect this change. It remains small even after adjusting the value in the MaxHeight property!

Is there a way for me to increase the DropDownHeight of my RadComboBox? Should I utilize any specific styling techniques? Any assistance would be greatly appreciated. Thank you.

Answer №1

If you want to adjust the width of the drop-down area for a RadComboBox, you can do so by customizing the default theme. Follow these steps:

  1. Open your project in Blend and select the RadComboBox.
  2. Go to Object-> Edit Template -> Edit a Copy.
  3. Look for a Control Template with an x:Key="NonEditableComboBox".
  4. Locate the Popup named x:Name="PART_Popup".
  5. Add a MaxWidth property with a value that suits your requirements.

I hope this solution proves useful to you.

Answer №2

Remember to always adjust the Height attribute of the RadComboBox element!
