I'm using an UltraTree in Outlook express mode, with no automatic size for column. I can't find a way to get width for each colum.
I have noticed that Layout Info is not always updated.
The PreferredCellSize/PreferredLabelSize properties of UltraTreeLayoutInfo return 0 for the width/height components when they are not set explicitly (It think that is what you mean by "not always updated"). If you like you can visit http://devcenter.infragistics.com/Protected/RequestFeature.aspx and submit a request for resolved versions of these properties; in the meantime, the following workaround will give you the column width by finding the associated UIElements:
private int GetColumnWidth( UltraTreeNodeColumn column ){ UltraTree treeControl = column != null ? column.Control : null; UltraTreeUIElement controlElement = treeControl != null ? treeControl.UIElement : null;
if ( controlElement != null ) { UltraTreeNodeColumnHeaderUIElement headerElement = controlElement.GetDescendant( typeof(UltraTreeNodeColumnHeaderUIElement), column ) as UltraTreeNodeColumnHeaderUIElement;
if ( headerElement != null ) return headerElement.Rect.Width; }
return 0;}
Hi Brian,
I'm using this bit of workaround code you provided for getting the column widths but I cant seem to get it working correctly. When I pass my column object into the GetDescendat method it just returns the headerElement as null, is there a way of retrieving a collection of all the columnheaderUIElements and then manually searching through them for the correct one?
Thanks,
Denis
