Examples

The following code example demonstrates how to use the DataGridViewBand.Frozen property, which is nearly identical to the Frozen property of the DataGridViewRow class. This code example is part of a larger example provided for the DataGridViewBand class.

// Freeze the first row.
void Button4_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   FreezeBand( dataGridView->Rows[ 0 ] );
}

void Button5_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   FreezeBand( dataGridView->Columns[ 1 ] );
}

void FreezeBand( DataGridViewBand^ band )
{
   band->Frozen = true;
   DataGridViewCellStyle^ style = gcnew DataGridViewCellStyle;
   style->BackColor = Color::WhiteSmoke;
   band->DefaultCellStyle = style;
}

// Freeze the first row.
private void Button4_Click(object sender, System.EventArgs e)
{

    FreezeBand(dataGridView.Rows[0]);
}

private void Button5_Click(object sender, System.EventArgs e)
{

    FreezeBand(dataGridView.Columns[1]);
}

private static void FreezeBand(DataGridViewBand band)
{
    band.Frozen = true;
    DataGridViewCellStyle style = new DataGridViewCellStyle();
    style.BackColor = Color.WhiteSmoke;
    band.DefaultCellStyle = style;
}

' Freeze the first row.
Private Sub Button4_Click(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles Button4.Click

    FreezeBand(dataGridView.Rows(0))
End Sub

Private Sub FreezeColumn(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles Button5.Click

    FreezeBand(dataGridView.Columns(1))
End Sub

Private Shared Sub FreezeBand(ByVal band As DataGridViewBand)

    band.Frozen = True
    Dim style As DataGridViewCellStyle = New DataGridViewCellStyle()
    style.BackColor = Color.WhiteSmoke
    band.DefaultCellStyle = style

End Sub

Remarks

This property lets you keep one or several rows of important information in place when a user scrolls through the DataGridView. All rows above the frozen row are also frozen.
