DataGrid單元格Click事件

</UserControl>

private void DGComm_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e) 
{ 
    //e.AddedCells[0].Column 
    IList<DataGridCellInfo> cells = e.AddedCells; 
    foreach (DataGridCellInfo di in cells) 
    { 
     DataRowView dvr = (DataRowView)di.Item; 
     MessageBox.Show(di.ToString()); 
    } 
}

我希望能夠操縱選定單元格。我試圖打印單擊的單元格的名稱，但它在DataRowView dvr =（DataRowView）di.Item上拋出無效的轉換異常;指出我無法將數據源轉換爲RowView。DataGrid單元格Click事件

我該如何解決這個問題？

編輯：Itemsources由

public ObservableCollection<object> dataGridRows = new ObservableCollection<object>(); 

private void InitProtocolParsers() 
     { 
      DGComm.ItemsSource = dataGridRows;

你如何將Itemsource提供給datagrid？ – 2012-07-24 02:53:51

您通過di.Item訪問對象的類型是DataRowView，但你結合實際業務對象沒有提供。所以無論你放在ObservableCollection<object>可以通過di.Item"訪問。

試試看

MessageBox.Show(di.Item.ToString())

，這將變得比較清楚，我希望。
