Telerik RadGrid conditional display

Question

This is my RadGrid code in asp.net page

<telerik:RadGrid ID="grvData" runat="server" GridLines="Horizontal" EnableEmbeddedSkins="false" CellPadding="0" BorderWidth="0px"
        Width="1000px" Height="300px" CellSpacing="0"
        OnItemCommand="grvData_ItemCommand"
        OnNeedDataSource="grvData_NeedDataSource" AllowPaging="True" AllowSorting="True"  Skin="skn_RadGridCustom"
        SkinsDir="|CurrentTheme|/" SkinsPath="|CurrentTheme|/" >
        <ClientSettings>
            <Scrolling AllowScroll="True" UseStaticHeaders="True" />
        </ClientSettings>
        <MasterTableView PageSize="10" 
            AllowFilteringByColumn="false" AutoGenerateColumns="False" DataKeyNames="Id" AllowSorting="True">

            <Columns>
                <telerik:GridBoundColumn DataField="Id" DataType="System.Int64" ReadOnly="True" UniqueName="Id" Display="true">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="DetailId" DataType="System.Int64" ReadOnly="True" UniqueName="DetailId" Display="true">
                </telerik:GridBoundColumn>
                <telerik:GridTemplateColumn FilterControlAltText="Filter Reject column" UniqueName="Reject" HeaderText="Reject" Display="true">
                    <ItemTemplate>
                        <telerik:RadButton ID="btnReject" runat="server" ButtonType="StandardButton" Text="Reject" CommandName="Reject" />
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>

How can I display Reject button with enabled/disabled mode based on column IsCancelled=1/0 from the stored procedure that is Databound to the RadGrid while loading the grid.

Please try with the below code snippet.

ASPX.CS Please subscribe the "ItemDataBound" event for your radgrid.

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
        {
                GridDataItem item = e.Item as GridDataItem;
                RadButton btnReject = item.FindControl("btnReject") as RadButton; 

                if (item.GetDataKeyValue("IsCancelled").ToString() == "1")
                {
                    btnReject.Enabled = true;
                }
        else
        {
                    btnReject.Enabled = false;  
        }

    }
}

ASPX To access the 'IsCancelled' field into C# code please assign this field as datakey.

<MasterTableView DataKeyNames="Id,IsCancelled">

Let me know if any concern.
