Disable Edit button for only one row in the grid

[Deepika]

Hi,
1. I have the grid with 7 columns, in that 4 are readonly during Edit. two of them are editable and one is the "Select" checkbox.
When I click a button external to the grid, I am triggering the initinsert event. During this, I want to copy the data as is for the readonly columns, from the row that is checked to the row that got added thru the initInsert event. How can I do this? [ Editable fields are editable here too]
2. Now that when the user enters data, if he tries to enter same data as above for the new row, then I need to allow him to do so, but should not allow him to edit the old row and need to disable the Edit button for that row.
Please suggest.
Thanks and Regards,
Deepika Karanth

Hello,

Please below code for option 1.
Let me know its work or not.
If not then elaborate your both cases and if possible then also provide screen shot.

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Insert New Row" />
       <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" OnItemCommand="RadGrid1_ItemCommand"
           OnNeedDataSource="RadGrid1_NeedDataSource"
           onitemdatabound="RadGrid1_ItemDataBound">
           <MasterTableView DataKeyNames="ID">
               <Columns>
