How to add a column to RadGridView with a button in some cells

Hello,

Thank you for your help. I have been trying to get your code to work in my application with not much of luck.

Here is what I have, a textBox and a button. The textBox is there to capture a unique value from the database. based of the results that are returned from the database the system will show the button or not.

For example a user type in "12345" and then clicks "Add". The system will then do a database look up and add the row to the gridview but depending of the "_itemType" value that is returned from the database I make a decision to show the button or not. or even to rename the button if needed.

my code will need to be something like this

GridViewDataRowInfo rowInfo = new GridViewDataRowInfo(radGridView1.MasterView);
                if (i._itemType == "act") {
                    //rowInfo.Cells["UpdateInfo"].ColumnInfo.IsVisible = true;
                } else if (i._itemType == "bct"){

                   //rowInfo.Cells["UpdateInfo"].ColumnInfo.IsVisible = true;

                   //change the button label
                } else {
                    //rowInfo.Cells["UpdateInfo"].ColumnInfo.IsVisible = false;
                }

How can I get this line of code to work in on button click event

GridCommandCellElement commandCell = e.CellElement as GridCommandCellElement;

 thank you for your help
