I am working on adding some excel export functionality to all of the grids in my application. I have played around with numerous options but I can't seem to get the results I need.

I have grids that use calculated columns and aggregates. When using the ExportDataOnly = true and Format="ExcelML" the calculated columns and aggregates do not appear on the export. Also, any formatting applied to data is lost.

When I set ExportDataOnly = false and use HTML format the column names are linked inside of excel, the filter fields appear, and all hell breaks loose when you have a detail table.

I've tried using the GridExporting event like this:

        protected void RadGridSearch_GridExporting(object source, GridExportingArgs e) 
        { 
            RadGridSearch.AllowSorting = false
            RadGridSearch.AllowFilteringByColumn = false
        } 

It does not seem to change the export behavior.

I need to be able to do one of 2 things, either have my aggregated data and calculated columns show up on data only exports, or be able to trim out all the extra garbage when using HTML format.

Any suggestions?

I did manage to make something happen, although it was undesired.

Using this code:

protected void ImageButtonExcelExport_Click(object sender, System.Web.UI.ImageClickEventArgs e) 
        { 
            RadGridSearch.MasterTableView.AllowFilteringByColumn = false
            RadGridSearch.MasterTableView.AllowSorting = false
            RadGridSearch.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.None; 
 
            RadGridSearch.Rebind(); 
            RadGridSearch.MasterTableView.ExportToExcel(); 
        } 

I can get the column headers to show up as text, and the buttons disappear, BUT, since I have disabled sorting and filtering, sorts and filters used on the Grid are not reflected in the export data.

I guess what I really need is for calculated and aggregates to show up when the show only data option is selected. Additionally on most grids I use the command buttons and I don't have an event hander for each page as this would add an enormous amount of unreusable code to my application.

No ideas on this yet?  All I need to do is export the entire grid to Excel without the sort links or buttons.

Hello James,

Issue 1: How to export RadGrid without the filter item (HTML Excel, ExportOnlyData="false")

When IgnorePaging is set to "false" you can use this approach:
protected void Button1_Click(object sender, EventArgs e)
{
    foreach (GridFilteringItem item in RadGrid1.MasterTableView.GetItems(GridItemType.FilteringItem))
        item.Visible = false;
    RadGrid1.MasterTableView.ExportToExcel();
}

This will work with IgnorePaging="true":
bool isExport = false;
protected void Button1_Click(object sender, EventArgs e)
{
    isExport = true;
    RadGrid1.MasterTableView.ExportToExcel();
}
 
protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (isExport && e.Item is GridFilteringItem)
        e.Item.Visible = false;
}


Issue 2: How to export RadGrid along with the aggregates and the calculated columns (ExcelML)
RadGrid's ExcelML engine fetches the data directly from the data source - all non-data rows/columns like footer aggregates and calculated columns will be ignored.
In fact, you can add the missing items manually, but this will require some coding - this is demonstred in the attached project.
