I wanted to clear datatable if it contains header. Was suggested to use DataTable.Columns.count > 0 to check. But I encounter an issue if the datatable hasn’t been populated yet as null is not an instance of an object. Please advise.
Hi @QTH ,
Have you tried activity
you can do a null check
IF(Not isNothing(YourDatatableVar),YourDatatableVar.Clone, new DataTable() )
How about the following?
dt = New DataTable()
You can try this
if condition = dt.columncount>0
Thanks all for the replies but as shared in my initial post there may be instances where the datatable isn’t populated yet and hence the solutions asking to count the columns will return an error. The suggestion to do a null check seems to work for non populated datatable.
Same goes for the approach to just reassign it as a new datatable but I’ve yet to check.
Thanks all for the advice.
