Exporting tips and tricks
If you would like to inject some extra information to the exported file (such as the date of the exported document or some other details), consider using the Caption
property of the master table or the detail table (when exporting grid hierarchy).
Note that this property is meaningful for export to Excel/Word. For PD
F export you will need to set ExportSettings -> ExportOnlyData = false
, define CommandItemTemplate
for this purpose and include these details as part of its content, for example:
| <telerik:RadGrid id="RadGrid1" runat="server" ....>
| [Add your details here]
