有关处理事件的更多信息，请参见使用事件。
下面的代码示例演示如何使用此事件执行通过编程实现的排序操作，该操作模拟在设置了另一行为时，单击 DataGridViewColumnHeaderCell 时的默认行为。在此示例中，SelectionMode 设置为 ColumnHeaderSelect，因此，单击 DataGridViewColumnHeaderCell 时会选择该列的内容。若要运行此示例，请将该代码粘贴到一个包含名为 dataGridView1 的 DataGridView 的窗体中，并确保所有事件都与它们的事件处理程序关联。
Private Sub dataGridView1_ColumnHeaderMouseClick(ByVal sender As Object, _
ByVal e As DataGridViewCellMouseEventArgs) _
Handles dataGridView1.ColumnHeaderMouseClick
Dim newColumn As DataGridViewColumn = _
dataGridView1.Columns(e.ColumnIndex)
Dim oldColumn As DataGridViewColumn = dataGridView1.SortedColumn
Dim direction As ListSortDirection
' If oldColumn is null, then the DataGridView is not currently sorted.
If oldColumn IsNot Nothing Then
' Sort the same column again, reversing the SortOrder.
If oldColumn Is newColumn AndAlso dataGridView1.SortOrder = _
SortOrder.Ascending Then
direction = ListSortDirection.Descending
Else
' Sort a new column and remove the old SortGlyph.
direction = ListSortDirection.Ascending
oldColumn.HeaderCell.SortGlyphDirection = SortOrder.None
End If
Else
direction = ListSortDirection.Ascending
End If
' Sort the selected column.
dataGridView1.Sort(newColumn, direction)
If direction = ListSortDirection.Ascending Then
newColumn.HeaderCell.SortGlyphDirection = SortOrder.Ascending
Else
newColumn.HeaderCell.SortGlyphDirection = SortOrder.Descending
End If
End Sub
private void dataGridView1_ColumnHeaderMouseClick(
object sender, DataGridViewCellMouseEventArgs e)
{
DataGridViewColumn newColumn = dataGridView1.Columns[e.ColumnIndex];
DataGridViewColumn oldColumn = dataGridView1.SortedColumn;
ListSortDirection direction;
// If oldColumn is null, then the DataGridView is not sorted.
if (oldColumn != null)
{
// Sort the same column again, reversing the SortOrder.
if (oldColumn == newColumn &&
dataGridView1.SortOrder == SortOrder.Ascending)
{
