Telerik UI for Windows 8 XAML

Note

BooleanFilterDescriptor is a Descriptor which filters by property of System.Boolean data type.

Properties:

  • PropertyName

    - Gets or sets the name of the property that is used to retrieve the value to filter by.

  • Value

    - Gets or sets the value used in the comparisons. This is the right operand of the comparison.

Now, we will show a simple example where we will filter by the PassesFilter property and the condition will be its value to be true:

XAML Copy imageCopy
<telerikGrid:RadDataGrid Width="300" VerticalAlignment="Center" x:Name="grid">
    <telerikGrid:RadDataGrid.FilterDescriptors>
        <telerikGrid:BooleanFilterDescriptor PropertyName="PassesFilter" Value="true"/>
    </telerikGrid:RadDataGrid.FilterDescriptors>
</telerikGrid:RadDataGrid>

Here we create sample data and set it as ItemsSource of our DataGrid:

C# Copy imageCopy
List<CustomData> data = new List<CustomData>
{
    new CustomData { Country = "Brazil", City = "Caxias do Sul", },
    new CustomData { Country = "Brazil", City = "Fortaleza", },
    new CustomData { Country = "Spain", City = "Malaga", PassesFilter = true },
    new CustomData { Country = "Bulgaria", City = "Koynare" },
    new CustomData { Country = "Spain", City = "Valencia", PassesFilter = true },
    new CustomData { Country = "Ghana", City = "Kade" },
    new CustomData { Country = "Brazil", City = "Porto Alegre" },
    new CustomData { Country = "Bulgaria", City = "Byala Slatina" },
    new CustomData { Country = "Brazil", City = "Joinville" },
};
this.grid.ItemsSource = data;

Where CustomData class defines our objects:

C# Copy imageCopy
public class CustomData
{
    public string Country { get; set; }

    public string City { get; set; }

    public bool PassesFilter { get; set; }
}

The first picture shows our RadDataGrid before passing the filter and the second after filtering:
