Making some column editable and some column noneditable using the asp:datagrid

Question

Hi In my datagrid i have 9 columns. In that 4 column should be noneditable. If i use the readonly property in the design mode. Always the column in noneditable. But for me when i click on the checkbox if it is true then that particular 4 column should be noneditable . If the checkbox is false all the 9 column should be editable. For me all the column editable is working fine. But i have problem with the column nonediting. In the design page i wrote as: asp : TemplateColumn HeaderText =IPAddress> ItemTemplate > asp : TextBox ID =txtaddress runat =server Text =' ' Enabled =false /> ItemTemplate > EditItemTemplate > asp : TextBox ID =txtaddress runat =server Text =' '/> EditItemTemplate > asp : TemplateColumn > In the edit command i wrote as below ((TextBox)e.Item.FindControl(txtaddress)).ReadOnly = true; Please help me with this question.
