I need to filter datatable for blanks

I have a datatable that has a status column. This column starts blank and once the first action is taken it is marked as found or not found. I want to be able filter the status column by blanks/null/empty but have been unsuccessful so far. i am using dtInvoiceNum.Select(“Status=Null”) to create an array of datarows and then doing a for each in the array.


Have you tried to use



dtInvoiceNum.Select(“Status=’ '”) ?


i have tried the second but not the first i will try that now. Thanks

Incase if above solution doesn’t work.

dtInvoiceNum.Select(“Status is NULL OR Status=''”)


Status is Null worked Thanks vvaidya

You can also use dtInvoiceNum.Select(“[Status]=‘Null’”).
