Hi Kumar,
Thank you for your interest in Syncfusion product.
If you want to add the Radio Button in DataBoundGrid control, then please try using InternalColumn.StyleInfo property in Binder to achieve this behavior. The InternalColmuns collection is maintained the GridDataBoundGrid columns. The Cell Type property is used to set the type of the cell. And the Choice List property is used to set the list for RadioButton cell.
Please refer the code below:
StringCollection sc = new StringCollection();
sc.Add("One");
sc.Add("Two");
this.gridDataBoundGrid1.Binder.InternalColumns["Col 2"].StyleInfo.CellType="RadioButton";
this.gridDataBoundGrid1.Binder.InternalColumns["Col 2"].StyleInfo.ChoiceList = sc;
this.gridDataBoundGrid1.Binder.InternalColumns["Col 2"].StyleInfo.TextAlign = GridTextAlign.Right;
Refer the sample in below link:

Lingaraj S.
