    I have a grid, in which particular cells need to be disabled.

    The enabled cells need to have a validator added to give a warning if the value isn't in a particular range, each cells range can be different

    I tried disabling the cell in the PreRender, or Item created, but the edit control still appears when you tab to the cell


     protected void PriceUpdateGrid_PreRender(object sender, EventArgs e)

                foreach (GridDataItem item in PriceUpdateGrid.MasterTableView.Items)
                    foreach (GridTableCell cell in item.Cells)
                       cell.Enabled = false;
                        cell.Item.Edit = false;
                    //item.Enabled = false;

            protected void PriceUpdateGrid_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
                if (e.Item is GridEditableItem)
                    GridEditableItem dataItem = (GridEditableItem)e.Item;
                    (e.Item as GridEditableItem)["377"].Enabled = false;
                    dataItem["377"].Enabled = false;
                    dataItem["377"] = false;
                    dataItem["377"].Controls[0].Enabled = false;
                    dataItem["377"].Visible = false;





     <telerik:RadGrid ID="PriceUpdateGrid" runat="server" RenderMode="Lightweight" ViewStateMode="Enabled"
            AllowSorting="False" GridLines="None" ShowGroupPanel="False" Skin="WebBlue" AutoGenerateColumns="False"
            OnNeedDataSource="PriceUpdateGrid_NeedDataSource" AllowMultiRowSelection="True"
            <PagerStyle AlwaysVisible="False" />
            <MasterTableView ClientDataKeyNames="SurveyEntityId" EnableViewState="true" DataKeyNames="SurveyEntityId,SubRegionSiteId" EditMode="Batch" CommandItemDisplay="TopAndBottom">
                <BatchEditingSettings EditType="Cell"></BatchEditingSettings>
                    <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" HeaderStyle-Width="40px">
                    <HeaderStyle Width="20px"></HeaderStyle>
                    <HeaderStyle Width="20px"></HeaderStyle>


            <ClientSettings EnableRowHoverStyle="true" AllowKeyboardNavigation="true">
                <ClientEvents OnBatchEditOpening="BatchEditOpening" />
                <Resizing AllowColumnResize="true" />
                <Selecting AllowRowSelect="True" UseClientSelectColumnOnly="True" />
                <Scrolling AllowScroll="True" UseStaticHeaders="True" />

    RadGrid with BatchEditing is designed entirely for client-side, and so if you wish to manipulate it, try using the Batch Editing Client-side API and Client-Side Programming Overview. One example would be to subscribe the grid to its OnBatchEditOpening client-side event, and in the event handler you can check column-cell is about to be edited. Cancel the event if necessary. That will prevent a cell from opening.

    If you wish to perform other logic on the cell, you might want to loop through the Grid rows using the GridCreated client-side event, get access to the cell and run your logic. Check out the Accessing Controls in Batch Edit Mode article for more.
