Property Value

Type: System::String
A string that specifies how rows are to be filtered. For more information, see the Remarks section.

To form a RowFilter value, specify the name of a column followed by an operator and a value to filter on. The value must be in quotation marks. For example:

"LastName = 'Smith'"

See the Expression property of the DataColumn class for more information.

To return only those columns with null values, use the following expression:

"Isnull(Col1,'Null Column') = 'Null Column'"
