I have added "CheckBoxUIElement" to GroupByRow in UltraWinGrid  by using the instructions in article http://devcenter.infragistics.com/Support/KnowledgeBaseArticle.aspx?ArticleID=4340

Though while loading the Grid i want to disable the state of the checkbox on UltraGridGroupByRow  Header dynamically based upon the data that is binded.

in the code we can find the UltraGridGroupByRow and on setting the tag property to Checked or Unchecked makes the checkBox Check/Uncheck.

Question is How to make the UltraGridGroupByRow checkbox at runtime and Enables its state enable and Disable

Thanks
