Examples

The following code example initializes this property so that the link changes color when it is selected. This example is part of a larger example available in the DataGridViewComboBoxColumn class overview topic.

private:
    void AddLinkColumn()
    {
        DataGridViewLinkColumn^ links = gcnew DataGridViewLinkColumn();

        links->UseColumnTextForLinkValue = true;
        links->HeaderText = ColumnName::ReportsTo.ToString();
        links->DataPropertyName = ColumnName::ReportsTo.ToString();
        links->ActiveLinkColor = Color::White;
        links->LinkBehavior = LinkBehavior::SystemDefault;
        links->LinkColor = Color::Blue;
        links->TrackVisitedState = true;
        links->VisitedLinkColor = Color::YellowGreen;

        DataGridView1->Columns->Add(links);
    }

private void AddLinkColumn()
{
    DataGridViewLinkColumn links = new DataGridViewLinkColumn();

    links.UseColumnTextForLinkValue = true;
    links.HeaderText = ColumnName.ReportsTo.ToString();
    links.DataPropertyName = ColumnName.ReportsTo.ToString();
    links.ActiveLinkColor = Color.White;
    links.LinkBehavior = LinkBehavior.SystemDefault;
    links.LinkColor = Color.Blue;
    links.TrackVisitedState = true;
    links.VisitedLinkColor = Color.YellowGreen;

    DataGridView1.Columns.Add(links);
}

Private Sub AddLinkColumn()

    Dim links As New DataGridViewLinkColumn()
    With links
        .UseColumnTextForLinkValue = True
        .HeaderText = ColumnName.ReportsTo.ToString()
        .DataPropertyName = ColumnName.ReportsTo.ToString()
        .ActiveLinkColor = Color.White
        .LinkBehavior = LinkBehavior.SystemDefault
        .LinkColor = Color.Blue
        .TrackVisitedState = True
        .VisitedLinkColor = Color.YellowGreen
    End With
    DataGridView1.Columns.Add(links)
End Sub

Remarks

When TrackVisitedState is true, the VisitedLinkColor property value is used to display links that have already been visited.

Getting or setting this property gets or sets the TrackVisitedState property of the object returned by the CellTemplate property. Setting this property also sets the TrackVisitedState property of every cell in the column and refreshes the column display. To override the specified value for individual cells, set the cell values after you set the column value.
