Dim instance As DataView
Dim value As String
value = instance.RowFilter
instance.RowFilter = value
public virtual string RowFilter { get; set; }

Property Value
Type:
System..::.StringA 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 Sub MakeDataView()
Dim view As DataView = New DataView
With view
.Table = DataSet1.Tables("Suppliers")
.AllowDelete = True
.AllowEdit = True
.AllowNew = True
.RowFilter = "City = 'Berlin'"
.RowStateFilter = DataViewRowState.ModifiedCurrent
.Sort = "CompanyName DESC"
End With
' Simple-bind to a TextBox control
Text1.DataBindings.Add("Text", view, "CompanyName")
End Sub
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");
}
