[Solved] Heirarchy table alignment

[Mike]

I have a Radgrid that has a MasterTable and a DetailsTable.  They basically have the same columns, the Master is top level view and the details is broken down data.  However, when I export the data to Excel the columns are no longer aligned.  How can I get them to align?

Thank You in advance!

Hi Mike,

I'm not clear about the issue. Below is a sample code snippet that works fine at my end. Can you please try and let me know if any concern. Provide your code snippet as well as a screenshot of the issue you are facing.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" EnableHierarchyExpandAll="true" RetainExpandStateOnRebind="true" AllowPaging="True" AllowSorting="true" OnDetailTableDataBind="RadGrid1_DetailTableDataBind" OnNeedDataSource="RadGrid1_NeedDataSource" >
    <MasterTableView DataKeyNames="CustomerID" HierarchyLoadMode="Client" CommandItemDisplay="Top">
        <DetailTables>
            <telerik:GridTableView DataKeyNames="OrderID" Name="Orders">
                <Columns>
                    <telerik:GridBoundColumn SortExpression="OrderID" HeaderText="OrderID" DataField="OrderID" >
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn SortExpression="OrderDate" HeaderText="Date Ordered" DataField="OrderDate" UniqueName="OrderDate" DataFormatString="{0:D}">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn SortExpression="Freight" HeaderText="Freight" DataField="Freight" UniqueName="Freight">
                    </telerik:GridBoundColumn>
                </Columns>
            </telerik:GridTableView>
        </DetailTables>
        <Columns>
            <telerik:GridBoundColumn SortExpression="CustomerID" HeaderText="CustomerID" DataField="CustomerID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn SortExpression="ContactName" HeaderText="Contact Name" DataField="ContactName">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn SortExpression="CompanyName" HeaderText="Company" DataField="CompanyName">
            </telerik:GridBoundColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>
<asp:Button ID="ExcelExport" runat="server" Text="Export To Excel" OnClick="ExcelExport_Click" />

C#:

protected void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
    if (!e.IsFromDetailTable)
    {
        RadGrid1.DataSource = GetDataTable("Select * from Customers");
    }
}

protected void RadGrid1_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)
{
    GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;
    switch (e.DetailTableView.Name)
    {
        case "Orders":
            {
                string CustomerID = dataItem.GetDataKeyValue("CustomerID").ToString();
                e.DetailTableView.DataSource = GetDataTable("SELECT * FROM Orders WHERE CustomerID = '" + CustomerID + "'");
              break;
            }
     }
}

protected void ExcelExport_Click(object sender, EventArgs e)
{
    RadGrid1.ExportSettings.ExportOnlyData = true;
    RadGrid1.ExportSettings.HideStructureColumns = true;
    RadGrid1.MasterTableView.HierarchyDefaultExpanded = true;
    RadGrid1.Rebind();
    RadGrid1.MasterTableView.ExportToExcel();
}
public DataTable GetDataTable(string query)
 {
   String ConnString = ConfigurationManager.ConnectionStrings["Northwind_newConnectionString3"].ConnectionString;
   SqlConnection conn = new SqlConnection(ConnString);
   SqlDataAdapter adapter = new SqlDataAdapter();
   adapter.SelectCommand = new SqlCommand(query, conn);

    DataTable myDataTable = new DataTable();
    conn.Open();
     try
      {
       adapter.Fill(myDataTable);
      }
     finally
      {
       conn.Close();
      }
    return myDataTable;
  }

Thank you for the reply.  What I am looking for is to have the columns in the Master Table align with the columns in the Details Table.  They are the same, but the details table is broken down line by line versus rolled up totals.

Currently, the details table columns are too far to the right.

Hi Mike,

Please take a look at this article on Aligning columns in each level of hierarchical grid.
