DataGridView.CellMouseDoubleClick 事件

定義

發生於 DataGridView 中的儲存格被按兩下時。Occurs when a cell within the DataGridView is double-clicked.

public:
 event System::Windows::Forms::DataGridViewCellMouseEventHandler ^ CellMouseDoubleClick;
public event System.Windows.Forms.DataGridViewCellMouseEventHandler CellMouseDoubleClick;
member this.CellMouseDoubleClick : System.Windows.Forms.DataGridViewCellMouseEventHandler 
Public Custom Event CellMouseDoubleClick As DataGridViewCellMouseEventHandler 

範例

下列程式碼範例示範如何使用這個成員。The following code example demonstrates the use of this member. 在此範例中,事件處理常式會報告 CellMouseDoubleClick 事件的發生。In the example, an event handler reports on the occurrence of the CellMouseDoubleClick event. 此報表可協助您瞭解事件發生的時間,並可協助您進行調試。This report helps you to learn when the event occurs and can assist you in debugging. 若要報告多個事件或經常發生的事件,請考慮使用 Console.WriteLine 取代 MessageBox.Show,或將訊息附加到多行 TextBoxTo report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

若要執行範例程式碼,請將它貼入專案,其中包含名為 DataGridView1DataGridView 類型的實例。To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. 然後確定事件處理常式與 CellMouseDoubleClick 事件相關聯。Then ensure that the event handler is associated with the CellMouseDoubleClick event.

private void DataGridView1_CellMouseDoubleClick(Object sender, DataGridViewCellMouseEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Button", e.Button );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Clicks", e.Clicks );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "X", e.X );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Y", e.Y );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Delta", e.Delta );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Location", e.Location );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "CellMouseDoubleClick Event" );
}
Private Sub DataGridView1_CellMouseDoubleClick(sender as Object, e as DataGridViewCellMouseEventArgs) _ 
     Handles DataGridView1.CellMouseDoubleClick

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Button", e.Button)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Clicks", e.Clicks)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "X", e.X)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Y", e.Y)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Delta", e.Delta)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Location", e.Location)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"CellMouseDoubleClick Event")

End Sub

備註

當使用者按兩下任何滑鼠按鍵時,就會發生這個事件。This event occurs when the user double-clicks using any of the mouse buttons. 使用 [MouseEventArgs.Button] 屬性來判斷按一下哪一個按鈕。Use the MouseEventArgs.Button property to determine which button was clicked.
