I've pretty much kept to the example here
http://www.telerik.com/community/code-library/aspnet-ajax/grid/export-multiple-radgrids-in-single-pdf-excel-file.aspx

except that I have two grids on separate rows, which I've done like this.

<telerik:RadGrid ID="rgridExport" AutoGenerateColumns="false" runat="server" OnNeedDataSource="rgridExport_NeedDataSource" ExportSettings-ExportOnlyData="false"

ExportSettings-OpenInNewWindow="true" OnItemDataBound="rgridExport_ItemDataBound" ShowHeader="false" AlternatingItemStyle-BackColor="White">

<MasterTableView>

<Columns>

<telerik:GridBoundColumn UniqueName="Id" DataField="Id" Visible="false" />

<telerik:GridTemplateColumn UniqueName="image">

<ItemTemplate>

<table width="100%">

<tr>

<td align="right" valign="middle" style="vertical-align:middle; width:50px;">

<asp:Image runat="server" ID="img" />

</td>

<td>

<telerik:RadGrid ID="rgrid" runat="server" Skin="Sitefinity" ItemStyle-HorizontalAlign="Center" AlternatingItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" >

<ExportSettings ExportOnlyData="true" OpenInNewWindow="true" />

</telerik:RadGrid>

</td>

</tr>

</table>

<br /><br /><br />

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

and the .cs file

protected void rgridExport_NeedDataSource(object sender, EventArgs e)

{

DataTable dt = new DataTable();

dt.Columns.Add("Id", typeof(int));

DataRow dr = dt.NewRow();

dr["Id"] = 1;

dt.Rows.Add(dr);

dr = dt.NewRow();

dr["Id"] = 2;

dt.Rows.Add(dr);

rgridExport.DataSource = dt;

}

protected void rgridExport_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

Image img = item["image"].FindControl("img") as Image;

RadGrid rgrid = item["image"].FindControl("rgrid") as RadGrid;

switch (item["Id"].Text)

{

case "1":

rgrid.ShowFooter = true;

rgrid.GridLines = GridLines.Horizontal;

rgrid.AllowPaging = true;

rgrid.AutoGenerateColumns = false;

rgrid.NeedDataSource += rgHitRatio_NeedDataSource;

rgrid.ItemDataBound += rgHitRatio_ItemDataBound;

rgrid.MasterTableView.ShowFooter = true;

rgrid.FooterStyle.Font.Bold = true;

GridBoundColumn col = new GridBoundColumn();

col.UniqueName = "Placed";

col.HeaderText = "Placed";

col.DataField = "Placed";

rgrid.Columns.Add(col);

col = new GridBoundColumn();

col.UniqueName = "#";

col.HeaderText = "#";

col.DataField = "#";

col.Aggregate = GridAggregateFunction.Sum;

col.FooterAggregateFormatString = "{0}";

rgrid.Columns.Add(col);

col = new GridBoundColumn();

col.UniqueName = "30";

col.HeaderText = "30";

col.DataField = "30";

col.Aggregate = GridAggregateFunction.Sum;

col.FooterAggregateFormatString = "{0}";

rgrid.Columns.Add(col);

col = new GridBoundColumn();

col.UniqueName = "60";

col.HeaderText = "60";

col.DataField = "60";

col.Aggregate = GridAggregateFunction.Sum;

col.FooterAggregateFormatString = "{0}";

rgrid.Columns.Add(col);

col = new GridBoundColumn();

col.UniqueName = "90";

col.HeaderText = "90";

col.DataField = "90";

col.Aggregate = GridAggregateFunction.Sum;

col.FooterAggregateFormatString = "{0}";

rgrid.Columns.Add(col);

col = new GridBoundColumn();

col.UniqueName = "Total";

col.HeaderText = "Total";

col.DataField = "Total";

col.Aggregate = GridAggregateFunction.Sum;

col.FooterAggregateFormatString = "{0}";

rgrid.Columns.Add(col);

col = new GridBoundColumn();

col.UniqueName = "Exhausted";

col.HeaderText = "Exhausted";

col.DataField = "Exhausted";

col.Aggregate = GridAggregateFunction.Sum;

col.FooterAggregateFormatString = "{0}";

rgrid.Columns.Add(col);

col = new GridBoundColumn();

col.UniqueName = "Rate";

col.HeaderText = "Rate";

col.DataField = "Rate";

col.Aggregate = GridAggregateFunction.Custom;

col.DataType = typeof(double);

col.FooterAggregateFormatString = "{0:N2}%";

col.DataFormatString = "{0:N2}%";

rgrid.Columns.Add(col);

img.ImageUrl = "~/Images/Clients/Summary.png";

break;

case "2":

rgrid.NeedDataSource += rgScoreCard_NeedDataSource;

img.ImageUrl = "~/Images/Clients/scorecard.png";

break;

}

if(rgrid != null)

rgrid.Rebind();

}

protected void btnExport_Click(object sender, EventArgs e)

{

rgridExport.MasterTableView.ExportToPdf();

}

On the screen, it looks fine, but when I export, I just get empty boxes (see attached)

Adding the colgroup and a static width mostly fixed it, but headers are now missing from my top grid. As you can see from my code above, I build the top grid in code behind, but the botton has autmatically generated columns. Only the one with auto generated columns has column headers.
