Examples

The following code example uses the GetLastColumn method to swap the last displayed column and the first displayed column.

// Swap the last column with the first.
void Button10_Click( Object^ /*sender*/, EventArgs^ /*args*/ )
{
   DataGridViewColumnCollection^ columnCollection = dataGridView->Columns;
   DataGridViewColumn^ firstDisplayedColumn = columnCollection->GetFirstColumn( DataGridViewElementStates::Visible );
   DataGridViewColumn^ lastDisplayedColumn = columnCollection->GetLastColumn( DataGridViewElementStates::Visible, DataGridViewElementStates::None );
   int firstColumn_sIndex = firstDisplayedColumn->DisplayIndex;
   firstDisplayedColumn->DisplayIndex = lastDisplayedColumn->DisplayIndex;
   lastDisplayedColumn->DisplayIndex = firstColumn_sIndex;
}

// Swap the last column with the first.
private void Button10_Click(object sender, EventArgs args)
{
    DataGridViewColumnCollection columnCollection = dataGridView.Columns;

    DataGridViewColumn firstVisibleColumn =
        columnCollection.GetFirstColumn(DataGridViewElementStates.Visible);
    DataGridViewColumn lastVisibleColumn =
        columnCollection.GetLastColumn(
            DataGridViewElementStates.Visible, DataGridViewElementStates.None);

    int firstColumn_sIndex = firstVisibleColumn.DisplayIndex;
    firstVisibleColumn.DisplayIndex = lastVisibleColumn.DisplayIndex;
    lastVisibleColumn.DisplayIndex = firstColumn_sIndex;
}

' Swap the last column with the first.
Private Sub Button10_Click(ByVal sender As Object, _
    ByVal args As EventArgs) Handles Button10.Click

    Dim columnCollection As DataGridViewColumnCollection = _
        dataGridView.Columns

    Dim firstVisibleColumn As DataGridViewColumn = _
        columnCollection.GetFirstColumn(DataGridViewElementStates.Visible)
    Dim lastVisibleColumn As DataGridViewColumn = _
        columnCollection.GetLastColumn(DataGridViewElementStates.Visible, _
        Nothing)

    Dim firstColumn_sIndex As Integer = firstVisibleColumn.DisplayIndex
    firstVisibleColumn.DisplayIndex = _
        lastVisibleColumn.DisplayIndex
    lastVisibleColumn.DisplayIndex = firstColumn_sIndex
End Sub

Remarks

The last column in display order is the column with the highest DisplayIndex value, regardless of whether the column is actually visible on the screen.

This method lets you determine the last column that fits the given criteria without having to compare index values directly.
