Hello Greg,

Please do not hesitate to contact with us if you need any further help on this.

Thank you for using Infragistics Components.

Nevermind, found it.  Some of the code for calculating the dropdown extents are not public so this is the closest I could get. 

Not perfect but it sizes without using the autosize.

Going to try this and see if it fixes it for me.

private int ColumnWidth()

{

if (DisplayLayout.SortedBands == null) return -1;

if (DisplayLayout.SortedBands.Count < 1) return -1;

int width = DisplayLayout.SortedBands[0].GetExtent() + DisplayLayout.SortedBands[0].GetOrigin();

return width + 30;

}

protected override void OnAfterDropDown(EventArgs e)

{

base.OnAfterDropDown(e);

int width = ColumnWidth();

if (DropDownWidth < width) DropDownWidth = width;

}

protected override void OnAfterDropDownResize(EventArgs e)

{

base.OnAfterDropDownResize(e);

int width = ColumnWidth();

if (DropDownWidth < width) DropDownWidth = width;

}

That's a good idea but it would take me a very long time to convert each combo box and columns to fixed width.
I may wind up doing this.

Can you please tell me if the source code to UltraDropDown / UltraCombo is available somewhere? 
I'm wondering if I can see how the sizing code works I could come up with a better workaround (like size the combo to a large fixed size if width is negative).
