Examples

The following code example demonstrates the use of the DataGridViewLinkColumn.TrackVisitedState property, which is similar to this property. 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 false, the LinkVisited property will not be automatically set to true when visited.

Setting the TrackVisitedState property of the owning column 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.
