Is auto-width supported for the RadComboBox? Is there a way to make it grow horizontally to the largest item in the select list?

Are there plans to make this a built-in feature? Since the standard DropDownList control automatically sizes itself to the data in the dropdown, it makes sense that many people might want to mimic this behavior without creating code for every single combobox on a form.

I would expect two properties: One that autosizes the dropdown width, and one that autosizes the combo itself.

I very much like some of the features of the telerik drop down, but hate that it takes so much work to make it work the way standard dropdowns do.

PS. This code seems to far overcompensate for the text width when using Arial as the font (in both the control's skin and the TextWidth function).

I second the request for an auto-width property. I really dislike the look of word-wrapped combo box entries. Like probably most developers, the contents of my combo boxes come from data in a database and I can't specify one width at design time that is going to look good in all cases. And copying that c# code all over the application to calculate the width in the DataBound event is a huge hassle.

+1, we went back to html selects because of this behavior.

rcbSlide will by default be as narrow as the dropdown selector's text; it does not expand horizontally to fit its content, so a horizontal scrollbar will be created if the dropdown item text is wide enough. This is fixable by manually setting rcbSlide's(minimum) size to be larger than its contents. This allows the content (rcbList,rcbScroll, rcbItem) to intelligently resize horizonally up to the width of rcbSlide.

Here is my CSS fix for the problem.

/* Allows radComboBox dropdowns to expand horizontally    rather than use a scrollbar */

.rcbSlide {
    width: 500px;
}

.rcbScroll .rcbWidth {

    min-width: 150px;

    width: auto;

}

.RadComboBoxDropDown {

    width: auto !important;

}

.rcbList {

    position: relative;

    width: auto;

}

I vote for this as well. Spent 15 minutes of my time looking for what I thought would be a standard.
