CellDoubleClick与CellMouseDoubleClick

Question

DataGridView有两个类似的事件处理程序：CellDoubleClick和CellMouseDoubleClick。这些有什么区别？

Answer 1

CellDoubleClick和CellClick是从左鼠标按钮触发的事件，以及从Tab键到项目并点击空格键等的“点击”。

鼠标点击任意按钮即可获得MouseDoubleClick和MouseClick。

另外Discussed on the MSDN Forums.

Answer 2

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的信息，请使用CellMouseDoubleClick事件。

请参阅：http://msdn.microsoft.com/de-de/library/system.windows.forms.datagridview.celldoubleclick.aspx

CellMouseDoubleClick-Event接收点击次数，位置（点，X，Y），MouseButton等

Answer 3

TL;博士 双击任何鼠标按钮时会触发CellDoubleClick。 只有在双击LEFT按钮时才会触发CellMouseDoubleClick。

// 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
