Hi Konstantin,
Thanks for the reply, this works perfectly. I implemented slightly differently, but this is definitely the working principle.
Because I knew that I had a single column, in which every row needed to be formatted as text, i simply grabbed all the columns and then implemented your solution on all the rows. Thanks again for the great solution.
protected void rgrBoundaryDefinitionList_InfrastructureExporting(object sender, GridInfrastructureExportingEventArgs e) { var cols = e.ExportStructure.Tables[0].Columns; var columnCount = cols.Count; for (int i = 1; i <= cols[1].Cells.Count; i++) { cols[1].Cells[1, i].Format = "@"; }}
