public string FilterString { get; set; }

Property Value

Type Default Description
String null

A string representation of a CriteriaOperator object which specifies the filtering criteria.


The string assigned to this property is automatically converted to criteria using CriteriaOperator.Parse and is set to the XPDataView.Filter property.

To clear filtering, assign an empty string to the FilterString property.


The following code snippet demonstrates filtering capabilities of the XPDataView. Filter criteria specified via the XPDataView.Filter and XPDataView.FilterString properties below, provide the identical functionality, and can be used interchangeably.

xpDataView1.Filter = CriteriaOperator.Parse("Age < 50");
xpDataView1.Filter = new BinaryOperator("Age", 50, BinaryOperatorType.Less);
xpDataView1.FilterString = "Age < 50";
