WPF工具包DataGrid SelectionChanged获取单元格值

请帮助我,我试图从SelectionChangedEvent中的选定行获取Cell [0]的值。

我只是设法得到许多不同的Microsoft.Windows.Controls,我希望我错过了一些愚蠢的东西。

希望我能从这里得到一些帮助……

private void datagrid_SelectionChanged(object sender, SelectionChangedEventArgs e) { Microsoft.Windows.Controls.DataGrid _DataGrid = sender as Microsoft.Windows.Controls.DataGrid; } 

我希望它会像…

 _DataGrid.SelectedCells[0].Value; 

但是.Value不是一个选择….

非常感谢这一直让我发疯! 担

请检查以下代码是否适合您:

 private void dataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e) { DataGrid dataGrid = sender as DataGrid; if (e.AddedItems!=null && e.AddedItems.Count>0) { // find row for the first selected item DataGridRow row = (DataGridRow)dataGrid.ItemContainerGenerator.ContainerFromItem(e.AddedItems[0]); if (row != null) { DataGridCellsPresenter presenter = GetVisualChild(row); // find grid cell object for the cell with index 0 DataGridCell cell = presenter.ItemContainerGenerator.ContainerFromIndex(0) as DataGridCell; if (cell != null) { Console.WriteLine(((TextBlock)cell.Content).Text); } } } } static T GetVisualChild(Visual parent) where T : Visual { T child = default(T); int numVisuals = VisualTreeHelper.GetChildrenCount(parent); for (int i = 0; i < numVisuals; i++) { Visual v = (Visual)VisualTreeHelper.GetChild(parent, i); child = v as T; if (child == null) child = GetVisualChild(v); if (child != null) break; } return child; } 

希望这会有所帮助,问候

更少的代码,它的工作原理。

 private void datagrid_SelectionChanged(object sender, SelectionChangedEventArgs e) { DataGrid dataGrid = sender as DataGrid; DataGridRow row = (DataGridRow)dataGrid.ItemContainerGenerator.ContainerFromIndex(dataGrid.SelectedIndex); DataGridCell RowColumn = dataGrid.Columns[ColumnIndex].GetCellContent(row).Parent as DataGridCell; string CellValue = ((TextBlock)RowColumn.Content).Text; } 

ColumnIndex是您想知道的列的索引。

由于您使用的是“SelectionChanged”,因此您可以将发件人用作数据网格:

 DataGrid dataGrid = sender as DataGrid; DataRowView rowView = dataGrid.SelectedItem as DataRowView; string myCellValue = rowView.Row[0].ToString(); /* 1st Column on selected Row */ 

我尝试了这里发布的答案并且很好,但在开始隐藏DataGrid中的列时给了我一些问题。 即使隐藏列,这个也适合我。 希望它也适合你。

这将为您提供WPF中DataGrid中当前选定的行: –

 DataRow dtr = ((System.Data.DataRowView)(DataGrid1.SelectedValue)).Row; 

现在获取单元格值只需写入dtr[0]dtr["ID"]等。

 private void datagrid_SelectionChanged(object sender, SelectionChangedEventArgs e) { DataGrid _DataGrid = sender as DataGrid; string strEID = _DataGrid.SelectedCells[0].Item.ToString(); }
