        GV_Update.DataBind();   
} protected void GV_Update_RowUpdating(object sender, GridViewUpdateEventArgs e,int Roll_ID, String Roll_Data, int Status) 
    { 
        WSRollInfo.WSRoll updateRolls = new WSRollInfo.WSRoll(); 
        GV_Update.DataSource = updateRolls.updateRoll(Roll_ID, Roll_Data, Status); 
        GV_Update.DataBind(); 
        BindNominal(); 
 
    }

set up a debug point. see if it reaches the RowEditing Event.

if no then Delete from Mark up and Delete from Gridview Event and
agaian generate the new RowEditing Event.

if yes then check this out. may be you are missing some part.
