RadControls for ASP.NET AJAX
Setting individual cells in read-only mode is not achievable in the current version of
Telerik RadGrid. A possible workaround, however, is to disable the respective cell server-side
to prevent the user from editing its content. This can be done by subscribing to the ItemCreated
event of the grid:
CopyASPX
<telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" AllowSorting="True"
runat="server" GridLines="None" Width="95%" AllowMultiRowEdit="True" HorizontalAlign="NotSet">
<MasterTableView Width="100%" DataSourceID="SqlDataSource1" EditMode="InPlace"
DataKeyNames="CustomerID">
<Columns>
<telerik:GridEditCommandColumn UniqueName="EditCommandColumn" />
</Columns>
</MasterTableView>
</telerik:RadGrid>
<br />
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
SelectCommand="SELECT * FROM [Customers]">
</asp:SqlDataSource>CopyVB.NET

If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then
If (CType(e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("CustomerID"), String) = "ALFKI") Then
CType(e.Item, GridEditableItem)("CustomerID").Enabled = False
End If
End If
End SubCopyC#

{
if (e.Item is GridEditableItem && e.Item.IsInEditMode)
{
if ((string)e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["CustomerID"] == "ALFKI")
{
(e.Item as GridEditableItem)["CustomerID"].Enabled = false;
}
}
}
