CellDoubleClick vs CellMouseDoubleClick

CellDoubleClick和CellClick是从左鼠标按钮触发的事件，以及从选项卡到项目和点击空格键等产生的"点击"。

鼠标双击和鼠标点击来自任何按钮的鼠标点击。

也在MSDN论坛上进行了讨论。

CellDoubleClick事件接收有关鼠标的更多信息。如果事件处理程序需要有关鼠标位置等信息，请使用CellMouseDoubleClick事件。

CellMouseDoubleClick事件接收点击计数、位置（点、X、Y）、鼠标按钮等

tl；博士双击任意鼠标按钮时，CellDoubleClick会激发。CellMouseDoubleClick仅在双击LEFT按钮时激发。

// Fires EVERY time ANY mouse button moves down
private void dataGridView1_MouseDown(object sender, MouseEventArgs e)
{
Console.WriteLine("MouseDown Event: " +  e.Button + " button." );
}

// Fires when the LEFT mouse button is double clicked
private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
Console.WriteLine(" CellDoubleClick: LEFT Button was double clicked");
}

// Fires when ANY mouse button is double clicked
private void dataGridView1_CellMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
{
Console.WriteLine(" CellMouseDoubleClick Event: SOME Button was double clicked");
}

结果是：

// MouseDown Event: Left button.
// MouseDown Event: Left button.
//  CellDoubleClick: LEFT Button was double clicked
//  CellMouseDoubleClick Event: SOME Button was double clicked
//  
//  
// MouseDown Event: Middle button.
// MouseDown Event: Middle button.
//  CellMouseDoubleClick Event: SOME Button was double clicked
// 
//  
//  MouseDown Event: Right button.
// MouseDown Event: Right button.
//  CellMouseDoubleClick Event: SOME Button was double clicked
