Using BindingSource Filters and Date Values

Hi, I'm using VB 2005, WinForms. I have a BindingSourse set to a DataGridView on one of my Forms. I've been able to filter within the DataGridView without a problem, except for DATE values.
I keep getting the following error message when I try to filter for the presence of a date within a column.

ERROR MESSAGE:
----------------------
An unhandled exception of type 'System.Data.EvaluateException' occurred in System.Data.dll
Additional information: Cannot perform '=' operation on System.DateTime and System.String.
---------------------

I've tried coding the filter in the following ways:

bs.Filter = "CanceledDate = ' ' "
bs.Filter = "CanceledDate = 'dbNull.Value'"

Neither seems to work.

I simply need to know if a Date value is present in the cell or if the cell is empty. If there is no Date present, then the item has not been canceled. If there is a Date value present in the cell, then the item was indeed canceled.

This is a syntax problem, but I can't seem to get it right.

Thanks for your help,
Fulano

Hi Marcelle, this is the error I got with the following line of code:

bs.Filter = "Canceled Date is null"

An unhandled exception of type 'System.Data.SyntaxErrorException' occurred in System.Data.dll

Additional information: Syntax error: Missing operand after 'Date' operator.

Any thoughts?

Thanks,
Fulano

Hi Marcelle, I fixed it...it should have been:

bs.Filter = "CanceledDate is null"  

Not

bs.Filter = "Canceled Date is null"

That worked!

Thanks!

Hi

Is Canceled Date the name of the field? If there is spaces in the field name that can cause errors. Yes, the 'is null' clause is more commonly used within the where clause of an sql query than in a filter, but if the date is sorted it may work. If Canceled Date contains a space it should be '  [Canceled Date] is null'
