DataGridView selectedRow屬性沒有獲得數據，如果我雙擊行？

Question

我點擊double dataGridView的任何一行。沒有得到數據點擊行數據：

    private void gwStudies_CellDoubleClick(object sender, DataGridViewCellEventArgs e) 
     { 
      GoruntuyuAc(); 
     } 

private void GoruntuyuAc() 
     { 
      olduid = ""; 
      DataRowView ro = (gwStudies.SelectedRows[0].DataBoundItem as DataRowView); 
      string uid = ""; 
      uid = ro["StudyInstanceUid"].ToString(); 
      string tarih = ""; 
      DateTime t1 = Convert.ToDateTime(ro["StudyDate"]); 
      //........ 
      //............ 
     }

上（gwStudies.SelectedRows [0]作爲.DataBoundItem DataRowView的）錯誤數據;

Answer 1

我不太確定，但我認爲選擇發生在雙擊事件後。

Answer 2

這裏你必須傳遞GoruntuyuAc（int row，int col）函數中的行索引和列索引。 像GoruntuyuAc（e.RowIndex，e.ColumnIndex）;

Answer 3

您可以訂閱SelectionChanged事件或嘗試這樣的事：

private void gwStudies_CellDoubleClick(object sender, DataGridViewCellEventArgs e) 
     { 
      olduid = ""; 
      DataRowView ro = (gwStudies.Rows[e.RowIndex].DataBoundItem as DataRowView); 
      string uid = ""; 
      uid = ro["StudyInstanceUid"].ToString(); 
      string tarih = ""; 
      DateTime t1 = Convert.ToDateTime(ro["StudyDate"]); 
      //........ 
      //............ 
     } 

Answer 4

只給你一個最佳實踐，爲了確保對點擊的DataGridView，你應該投發件人如下

void transactionsGridView_CellDoubleClick(object sender, DataGridViewCellEventArgs e) 
    { 
     DataGridView senderDataGrid = (DataGridView)sender; 
     YourBoundModelClass row = 
      (senderDataGrid.Rows[e.RowIndex].DataBoundItem as YourBoundModelClass); 
     //... 
    } 

這也是強類型。
