DataGridView.CellContentDoubleClick DataGridView.CellContentDoubleClick DataGridView.CellContentDoubleClick DataGridView.CellContentDoubleClick Event

定義

發生於使用者按兩下儲存格的內容時。Occurs when the user double-clicks a cell's contents.

public:
 event System::Windows::Forms::DataGridViewCellEventHandler ^ CellContentDoubleClick;
public event System.Windows.Forms.DataGridViewCellEventHandler CellContentDoubleClick;
member this.CellContentDoubleClick : System.Windows.Forms.DataGridViewCellEventHandler 
Public Custom Event CellContentDoubleClick As DataGridViewCellEventHandler 

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CellContentDoubleClick事件的發生次數。In the example, an event handler reports on the occurrence of the CellContentDoubleClick 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MessageBox.ShowConsole.WriteLine取代為, 或將訊息附加TextBox至多行。To 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, 請將它貼入包含名為DataGridView DataGridView1之類型實例的專案中。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CellContentDoubleClick事件相關聯。Then ensure that the event handler is associated with the CellContentDoubleClick event.

private void DataGridView1_CellContentDoubleClick(Object sender, DataGridViewCellEventArgs 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();
MessageBox.Show(messageBoxCS.ToString(), "CellContentDoubleClick Event" );
}
Private Sub DataGridView1_CellContentDoubleClick(sender as Object, e as DataGridViewCellEventArgs) _ 
     Handles DataGridView1.CellContentDoubleClick

    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()
    MessageBox.Show(messageBoxVB.ToString(),"CellContentDoubleClick Event")

End Sub
