The GridView has the ElementExporting event allowing user to customize the element being exported and/or take other actions.
Apparently sometimes the custom-formatted row cell values assigned to the GridViewElementExportingEventArgs.Value property in the handler of such event are dropped and the corresponding cells display as blank in the exported Excel doc. The examination of generated HTML file confirms that the values are indeed missing. The error has irregular random nature; no pattern/condition for its occurrence has been found. Sometimes of two documents generated from the same grid with the same data one may have all cells populated, and another missing some values.
Is this issue known to Telerik? Are there any additional required actions (setting some flag, etc.) when overriding the Value property of the GridViewElementExportingEventArgs class with the custom value for the row cell?
