I am exporting a WHDG control to excel using WebExcelExporter. Everything works great (I see all data, I see correct column groupings, I see proper column reordering, etc) EXCEPT for an empty footer value.
All binding is done in code-behind as the data source is determined in runtime. I manually create the columns on the WHDG.GridView property and bind a DataSet (containing just one DataTable) to the grid control. If a column is of a specific data type, I manually create the summary row setting via:
whdgReport.GridView.Behaviors.SummaryRow.Enabled = true; var sumRowSetting = new SummaryRowSetting() { ColumnKey = rc.ColumnName, ShowSummaryButton = false, FormatString = "{0:c}" }; sumRowSetting.SummarySettings.Add(new SummarySetting(SummaryType.Sum) { FormatString = "{1}" }); whdgReport.GridView.Behaviors.SummaryRow.ColumnSettings.Add(sumRowSetting); var colSummaryInfo = new ColumnSummaryInfo() { ColumnKey = rc.ColumnName }; colSummaryInfo.Summaries.Add(new Summary() { SummaryType = SummaryType.Sum }); whdgReport.GridView.Behaviors.SummaryRow.ColumnSummaries.Add(colSummaryInfo);
When I export to excel, I correctly see a summary row and a value in the correct column, it just has a value of 0 instead of the sum of the columns.
Am I missing anything obvious? After seeing all the data appear in the grid (along with the correct user edits -- column groupings and reordering), I was surprised to see the footer not get calculated correctly.
Thanks!

I'm likely missing something obvious -- how do I get a reference to the resulting excel spreadsheet to change its formatting?
Looking at the Exporting and Exported events (and they're accompanying EventArgs objects), I can't find access to columns, either the grid's or the spreadsheet's.
Um, it's kind of however you want. You could handle exporting or exported events, go through grid columns and then set appropriate formats on the excel columns. Rather than handling a cell exporting and doing it multiple times. But those events you mention would work too.

Hi kfiduk,
You could turn off the DataFormatString on the grid column, but then set a format string on the excel spreadsheet column.
regards,David Young
Is there a best practice way of going about doing this?
Currently, I'm clearing out all DataFormatString properties of my columns like so before exporting it:
whdgReport.GridView.Columns.OfType<FormattedGridField>().ToList().ForEach(col => col.DataFormatString = string.Empty);
This is working correctly and gets the correct sum value in the footer of the exported spreadsheet. There may be a more "correct" way of doing this, tho.
I'm lost on the second part though. After I've exported, how do I reformat the excel spreadsheet column back to currency/money? Hook into an event of WebExcelExporter? I see a couple possible candidates in CellExported and SummaryCellExported.
Thanks for the guidance!
