Accessing Tables (GridTableView objects) in RadGrid - server side

MasterTable of a Grid

protected void RadButton1_Click(object sender, EventArgs e)
{
    GridTableView masterTable = RadGrid1.MasterTableView;
}

DetailTables of a Hierarchical Grid

In a hierarchical grid, each item in the Items collection of a parent GridTableView has a ChildItem property of type GridNestedViewItem. This child item is the container for the nested child table(s). The GridNestedViewItem has a NestedTableViews property that holds the collection of all the detail tables for the parent table.

Example markup

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource">
    <MasterTableView Name="MasterTable">
        <DetailTables>
            <telerik:GridTableView Name="ChildTable1">
                <DetailTables>
                    <telerik:GridTableView Name="GrandChildTable1">
                    </telerik:GridTableView>
                    <telerik:GridTableView Name="GrandChildTable2">
                    </telerik:GridTableView>
                </DetailTables>
            </telerik:GridTableView>
            <telerik:GridTableView Name="ChildTable2">
                <DetailTables>
                    <telerik:GridTableView Name="GrandChildTable1">
                    </telerik:GridTableView>
                    <telerik:GridTableView Name="GrandChildTable2">
                    </telerik:GridTableView>
                </DetailTables>
            </telerik:GridTableView>
        </DetailTables>
    </MasterTableView>
</telerik:RadGrid>

Code behind examples

You can use these properties to access the detail tables of a row in the parent table, as follows:

GridTableView firstDetail = RadGrid1.MasterTableView.Items[0].ChildItem.NestedTableViews[0];
Dim firstDetail As GridTableView = RadGrid1.MasterTableView.Items(0).ChildItem.NestedTableViews(0)

Conversely, if you have a reference to the instance of an item in a child table and want to access the parent table view, you can use the ParentItem property.

GridTableView parentTable = childItem.OwnerTableView.ParentItem.OwnerTableView;
Dim parentTable As GridTableView = childItem.OwnerTableView.ParentItem.OwnerTableView

You can also Iterate through the DetailTables GridTableViewCollection

protected void RadButton1_Click(object sender, EventArgs e)
{
    foreach (GridTableView childTable in RadGrid1.MasterTableView.DetailTables)
    {
        if (childTable.Name == "ChildTable1")
        {
            childTable.AllowSorting = true;

        }
        else if (childTable.Name == "ChildTable2")
        {
            childTable.AllowFilteringByColumn = true;
        }
        childTable.Rebind();

        foreach (GridTableView grandChildTable in childTable.DetailTables)
        {
            if (grandChildTable.Name == "GrandChildTable1")
            {
                grandChildTable.AllowFilteringByColumn = true;
            }
            else if (grandChildTable.Name == "GrandChildTable2")
            {
                grandChildTable.AllowSorting = true;
            }

            grandChildTable.Rebind();
        }
    }
}
