I've radiobutton inside a cellvalue presenter. I need to make the radibutton as checked when the record is activated. Kindly suggest me how to find the radiobutton inside the active record.
To find this radio button, you can use the GetDescendant|GetAncestor methods of the Infragistics.Windows.Utilities class. This however is not necessary. In the template of the CellValuePresenter, you can bind the Radio Button's IsChecked property to the DataRecordPresenter's Record.IsActive property.
I think I created a sample project for this, which you can find in this forum thread:
