Hi ,

I am using Telerik RadGrid in my application having multilevel hierachy i.e the Master table has a detail table which again has one more detail table.Export to excel with same grid is working fine but I am facing the following two issues with export to word.
1.  When I try to export the grid details to word only the first row of the grid is expanded and completely exported and the other rows are not not expanded only the Master Table rows are displayed.
2. When I again click the export to word only the parent i.e master table rows are exported to the doc file.

I have used the disable ajax for export and set the following properties to the grid

 
grid.MasterTableView.HierarchyDefaultExpanded = true;
            if (grid.MasterTableView.HasDetailTables)
            {
                foreach (GridTableView gridTableView in grid.MasterTableView.DetailTables)
                {
                    // Added by partner CB to Fix defect 15597
                    gridTableView.AllowPaging = false;
                    gridTableView.HierarchyDefaultExpanded = true;
                }
            }
           
grid.ItemCreated += new GridItemEventHandler(RadGrid_ItemCreated);
            grid.ExportSettings.ExportOnlyData = true;
            grid.ExportSettings.IgnorePaging = true;
            grid.ExportSettings.OpenInNewWindow = true;

  grid.MasterTableView.ExpandCollapseColumn.Display = false;
        grid.MasterTableView.HierarchyLoadMode = GridChildLoadMode.Client;
        grid.MasterTableView.DetailTables[0].ExpandCollapseColumn.Display = false;
        grid.MasterTableView.DetailTables[0].DetailTables[0].ExpandCollapseColumn.Display = false;


Please help me in this.

Thanks,

Hi Rahul Kasar,

I tried to export a 3 Level hierarchy Grid and it works fine. Here is a sample code snippet.

ASPX:
<asp:Button ID="Button1" runat="server" Text="Export To Word" onclick="Button1_Click" />

C#:
protected void Button1_Click(object sender, EventArgs e)
{
    RadGrid1.ExportSettings.IgnorePaging = true;
    RadGrid1.ExportSettings.ExportOnlyData = true;
    RadGrid1.MasterTableView.HierarchyDefaultExpanded = true;
    if (RadGrid1.MasterTableView.HasDetailTables)
    {
        foreach (GridTableView gridTableView in RadGrid1.MasterTableView.DetailTables)
        {            
            gridTableView.HierarchyDefaultExpanded = true;
        }
    }
    RadGrid1.MasterTableView.ExportToWord();
}

Thanks,
Princy

Hi Rahul Kasar,

Can you please try Rebinding the Grid on Export to Word, in the OnClick event WordImageButton_Click():

C#:
RadGrid1.MasterTableView.HierarchyDefaultExpanded = true;
RadGrid1.MasterTableView.DetailTables[0].HierarchyDefaultExpanded = true;
RadGrid1.Rebind();
RadGrid1.MasterTableView.ExportToWord();

Hi Princy,

Thanks for the quick response. I tried the same but still getting the same issue :

 RadGrid1.MasterTableView.ExpandCollapseColumn.Display = false;
        RadGrid1.MasterTableView.DetailTables[0].ExpandCollapseColumn.Display = false;
        RadGrid1.MasterTableView.DetailTables[0].CommandItemDisplay = GridCommandItemDisplay.None;
        GridTemplateColumn gridTemplateColumn = RadGrid1.MasterTableView.DetailTables[0].Columns.FindByUniqueName("GridTemplateColumn") as GridTemplateColumn;
        if (templateEditColumn != null)
            templateEditColumn.Visible = false;
        RadGrid1.MasterTableView.Columns.FindByUniqueName(columnUniqueName).Display = false;
        RadGrid1.MasterTableView.HierarchyDefaultExpanded = true;
        RadGrid1.ItemCreated += new GridItemEventHandler(RadGrid_ItemCreated);
        RadGrid1.ExportSettings.ExportOnlyData = true;
        RadGrid1.ExportSettings.IgnorePaging = true;
        RadGrid1.ExportSettings.OpenInNewWindow = true;
        RadGrid1.ExportSettings.FileName = fileName;
        if (RadGrid1.MasterTableView.HasDetailTables)
        {
            foreach (GridTableView gridTableView in RadGrid1.MasterTableView.DetailTables)
            {
                gridTableView.AllowPaging = false;
                gridTableView.HierarchyDefaultExpanded = true;
           //     RadGrid1.MasterTableView.DetailTables[0].Rebind();
    RadGrid1.Rebind();
            }
        }

        RadGrid1.MasterTableView.ExportToWord();

I tried with both options to rebind the detail table and the parent grid but didnt worked.

Please suggest.

Hi Princy,

Thanks for the response. In my case the grid with detail table is exported properly to excel. But incase of word it fails to export detail table. I have used similar settings for word and excel export.

Please suggest.

Hi Princy,

I have resolved this issue. In the Item Created event of the Grid there was a code to expand /collapse the grid items. I have manipulated the code to resolve the issue.

Thanks for your support

Hi Karu,

I was not able to replicate this issue at my end. Make sure you have expanded all level on export.

C#:
RadGrid1.MasterTableView.HierarchyDefaultExpanded = true; //Expand 1st level
RadGrid1.MasterTableView.DetailTables[0].HierarchyDefaultExpanded = true;//Expand 2nd level   
RadGrid1.MasterTableView.DetailTables[0].DetailTables[0].HierarchyDefaultExpanded = true;//Expand 3rd level
//so on..

Thanks,
Princy
