範例

下列程式碼範例會處理 事件， RowContextMenuStripNeeded 以根據員工的職稱提供 ContextMenuStrip 。 在此範例中，有兩個快顯功能表，一個用於經理，另一個用於所有其他員工。 此範例是類別概觀中較大範例的 DataGridViewRowContextMenuStripNeededEventArgs 一部分。

void dataGridView1_RowContextMenuStripNeeded(object sender,
    DataGridViewRowContextMenuStripNeededEventArgs e)
{
    DataGridViewRow dataGridViewRow1 = dataGridView1.Rows[e.RowIndex];

    toolStripMenuItem1.Enabled = true;

    // Show the appropriate ContextMenuStrip based on the employees title.
    if ((dataGridViewRow1.Cells["Title"].Value.ToString() ==
        "Sales Manager") ||
        (dataGridViewRow1.Cells["Title"].Value.ToString() ==
        "Vice President, Sales"))
    {
        e.ContextMenuStrip = managerMenuStrip;
    }
    else
    {
        e.ContextMenuStrip = employeeMenuStrip;
    }

    contextMenuRowIndex = e.RowIndex;
}

Public Sub dataGridView1_RowContextMenuStripNeeded( _
    ByVal sender As Object, _
    ByVal e As DataGridViewRowContextMenuStripNeededEventArgs) _
    Handles dataGridView1.RowContextMenuStripNeeded

    Dim dataGridViewRow1 As DataGridViewRow = _
    dataGridView1.Rows(e.RowIndex)

    toolStripMenuItem1.Enabled = True

    ' Show the appropriate ContextMenuStrip based on the employees title.
    If dataGridViewRow1.Cells("Title").Value.ToString() = _
        "Sales Manager" OrElse _
        dataGridViewRow1.Cells("Title").Value.ToString() = _
        "Vice President, Sales" Then

        e.ContextMenuStrip = managerMenuStrip
