Hi,

I want to find the parent of the parent in a hierarchy grid structure. I have this:

<telerik:RadGrid ID="RadGrid1" runat="server" Width="50%" ShowStatusBar="true" AutoGenerateColumns="False"

PageSize="50" AllowSorting="True" AllowMultiRowSelection="False" AllowPaging="True"

OnDetailTableDataBind="RadGrid1_DetailTableDataBind" OnNeedDataSource="RadGrid1_NeedDataSource"

OnPreRender="RadGrid1_PreRender">

<PagerStyle Mode="NumericPages"></PagerStyle>

<MasterTableView Width="100%" DataKeyNames="ServiceName" AllowMultiColumnSorting="True">

<DetailTables>

<telerik:GridTableView DataKeyNames="MethodName" Name="MethodName" Width="100%">

<DetailTables>

<telerik:GridTableView DataKeyNames="ParameterName" Name="ParameterName" Width="100%">

<Columns>

<telerik:GridBoundColumn SortExpression="ParameterName" HeaderText="Parameter Name"

HeaderButtonType="TextButton" DataField="ParameterName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="ParameterType" HeaderText="Parameter Type"

HeaderButtonType="TextButton" DataField="ParameterType">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Parameter Value" UniqueName="ParamWrapper">

<ItemTemplate>

<asp:TextBox runat="server" ID="ParameterValue" Text='<%# DataBinder.Eval(Container.DataItem, "ParameterValue") %>'></asp:TextBox>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridBoundColumn SortExpression="MethodName" HeaderText="Method Name" HeaderButtonType="TextButton"

DataField="MethodName" UniqueName="MethodName">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Status">

<ItemTemplate>

<asp:Button runat="server" ID="btnMethodStatus" OnClick="btnMethodStatus_OnClick"

Text="-"></asp:Button>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Elapsed time">

<ItemTemplate>

<asp:Label runat="server" ID="lblElapsedTime" Text="0">

</asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Last executed on">

<ItemTemplate>

<asp:Label runat="server" ID="lblLastTimeExecuted" Text="-">

</asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridBoundColumn SortExpression="ServiceName" HeaderText="Service Name" HeaderButtonType="TextButton"

DataField="ServiceName">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Status">

<ItemTemplate>

<asp:Button runat="server" ID="btnServiceStatus" OnClick="btnServiceStatus_OnClick"

Text="-"></asp:Button>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Elapsed time">

<ItemTemplate>

<asp:Label runat="server" ID="lblElapsedTime" Text="0">

</asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Last executed on">

<ItemTemplate>

<asp:Label runat="server" ID="lblLastTimeExecuted" Text="-">

</asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Code behind:

protected void RadGrid1_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)

{

GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;

switch (e.DetailTableView.Name)

{

case "MethodName":

{

e.DetailTableView.DataSource = Method.GetMethods((string)dataItem.GetDataKeyValue("ServiceName"));

break;

}

case "ParameterName":

{

//TODO: Get ParentItem

e.DetailTableView.DataSource = Parameter.GetParameters((string)dataItem.GetDataKeyValue("MethodName"), (string)parentItem.GetDataKeyValue("ServiceName"));

break;

}

}

In the case "ParamenterName", I need to be able to find the parent of the parent of the EventArgs e. Right now I can easily get the immediate parent, what I need is one step above.

Thanks in advance,
