“Cannot find column” DataTable error while grouping or sorting Infragistics UltraWebGrid

By , 05/28/2010 11:08 AM

If you’re binding an ADO.NET DataTable to Infragistics UltraWebGrid and then programmaticaly sort the grid (e.g. add a column to a band’s SortedColumns collection) you may get an error:

Cannot find column My Column Name.

with stack trace starting from grid databinding and finishing in datatable’s sorting:

at System.Data.DataTable.ParseSortString(String sortString)
at System.Data.DataView.CheckSort(String sort)
at System.Data.DataView.set_Sort(String value)
at Infragistics.WebUI.UltraWebGrid.DBBinding.ProcessDataViewForFillRows(DataView dataView, RowsCollection rows)
at Infragistics.WebUI.UltraWebGrid.DBBinding.FillRows(UltraWebGrid grid, RowsCollection rows, IEnumerable datasource)
at Infragistics.WebUI.UltraWebGrid.DBBinding.BindList(IEnumerable datasource)
at Infragistics.WebUI.UltraWebGrid.DBBinding.DataBind(Object dataSource, String dataMember)
at Infragistics.WebUI.UltraWebGrid.UltraWebGrid.DataBind()

If the grid binds OK without sorting and grouping, but fails with either – most likely the culprit is one of the columns in data table. Continue reading '“Cannot find column” DataTable error while grouping or sorting Infragistics UltraWebGrid'»
