Creating a simpleDataGridWith data surrounded by Tag.
ModifyingDataGridTo render Tags inside the header row.
Creating a style sheet that will lockDataGridHeader row and column (s ).
Locking the column (s) from the client side.
Locking the column (s) for the server side.

Radiobutton is used to select a single option.ArticleThis section describes how to apply this feature to the DataGrid Control.First, we know that all the controls in the DataGrid will have a single uniqueid after the page is generated, so you put radionbuttonlist as the control directly in the DataGrid, even if you set groupname to the same, but it will be differ
