Examples

The following example shows a DataGridHyperlinkColumn that sets the Uri with the Binding property and the hyperlink text with the ContentBinding property. The Hyperlink.Click event is handled automatically because NavigationWindow is the parent of the DataGrid.

    <DataGrid Name="DG1" ItemsSource="{Binding}" AutoGenerateColumns="False" >
        <DataGrid.Columns>

<!--The Email property contains a URI.  For example "mailto:lucy0@adventure-works.com"-->
<DataGridHyperlinkColumn Header="Email" Binding="{Binding Email}"  ContentBinding="{Binding Email, Converter={StaticResource EmailConverter}}" />

            </DataGrid.Columns>

Remarks

Use DataGridHyperlinkColumn to display data that contains a Uri, such as an HTTP address or email address. The following illustration shows an example of a DataGridHyperlinkColumn.

Note

Hyperlink navigation can only occur if either the direct or indirect parent of a Hyperlink is a navigation host. Examples of navigation hosts include NavigationWindow, Frame, or any browser that can host XBAPs. For more information, see the "Navigation Hosts" article in Navigation Overview.

For more information about XBAP support, see Frequently asked questions about WPF browser-hosted applications (XBAP).

To populate the column, bind the column to the Uri data by using the Binding property. To display hyperlink text that is different than the URI string, bind the text value to the ContentBinding property. The Binding property is applied to the Hyperlink or TextBox element created in the column. The DataContext for the element in each cell is the data item for the row the cell is in. Therefore, to set up the binding you only have to set the Binding.Path. Optionally, you can specify a Binding.Converter if you want to convert the data. For more information about data binding, see Data Binding (WPF).

Note

DataGridHyperlinkColumn creates a Hyperlink element in the non-editing mode and a TextBox element in the editing mode.

If you want to display other types of data, DataGrid provides the following column types:

Column Type	Data Display
DataGridCheckBoxColumn	Use to display Boolean data.
DataGridComboBoxColumn	Use to display enumeration data.
DataGridTextColumn	Use to display text.

If you want to use other controls in your DataGrid, you can create your own column types by using DataGridTemplateColumn.

Constructors

DataGridHyperlinkColumn()

Initializes a new instance of the DataGridHyperlinkColumn class.
