事件類型

範例

下列程式碼範例示範如何使用這個成員。 在此範例中，事件處理常式會報告事件的發生次數 ColumnHeaderMouseDoubleClick 。 此報告可協助您瞭解事件發生的時間，並可協助您進行偵錯。 若要報告多個事件或經常發生的事件，請考慮將 取代 MessageBox.Show 為 Console.WriteLine 或將訊息附加至多行 TextBox 。

若要執行範例程式碼，請將它貼入包含名為 DataGridView1 之類型 DataGridView 實例的專案。 然後，確定事件處理常式與 事件相關聯 ColumnHeaderMouseDoubleClick 。

private void DataGridView1_ColumnHeaderMouseDoubleClick(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(), "ColumnHeaderMouseDoubleClick Event" );
}

Private Sub DataGridView1_ColumnHeaderMouseDoubleClick(sender as Object, e as DataGridViewCellMouseEventArgs) _ 
     Handles DataGridView1.ColumnHeaderMouseDoubleClick

    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(),"ColumnHeaderMouseDoubleClick Event")
