ComboBoxColumn drop down width

[troy]

I'm looking for a way to set the drop-down width for a ComboBoxCoumn to the same width of the column.

Hello Troy,

You can set a width for the GridViewComboBoxColumn's editor that is RadComboBox like this:

<Style TargetType="telerik:RadComboBoxItem">
    <Setter Property="MaxWidth" Value="130"/>
</Style>

I must say that there is no Width property for the drop-down of the RadComboBox, so I suggest you to use ItemTemplate and Text Wrapping for the ComboBoxColumn. Check this help article which shows you how to use template. Note that there are 4 pixels deviation between drop-down's width and Column's width. For your convenience I have made sample project that shows you the approach. You can find it attached.

All the best,

that would work great if I only had a single combo box.  I have several different combo boxes on this window and I don't want their width limited to what I need for the combo box column.

Hello,

When you are defining a style, you have two options - to apply it explicitly or implicitly. The first one - explicit - means that you have added a x:Key attribute to the style and use it afterwards as a StaticResource. This style will be applied only to those elements to which you explicitly set it - like in the GridViewComboBoxColumn.
