Property Value

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'"

The following example creates a DataView and sets its RowFilter property.

private void MakeDataView() 
{
    DataView view = new DataView();

    view.Table = DataSet1.Tables["Suppliers"];
    view.AllowDelete = true;
    view.AllowEdit = true;
    view.AllowNew = true;
    view.RowFilter = "City = 'Berlin'";
    view.RowStateFilter = DataViewRowState.ModifiedCurrent;
    view.Sort = "CompanyName DESC";

    // Simple-bind to a TextBox control
    Text1.DataBindings.Add("Text", view, "CompanyName");
}
