In UltraGrid we were able to use the property "currentRow.Band.Columns(k).HasValueList" but i don't see an equivalent for webdatagrid.
If you want to use Bands, you should use WebHierarchicalDataGrid. You can get the columns of a band like this:
protected void whdg_InitializeBand(object sender, BandEventArgs e)
Please let us know if you need further assistance.
I am not looking at WebHierarchicalDataGrid but normal webdatagrid. Can i just check if GridRecorditem.Value!=Null to mimic the old HasValueList functionality?
