WPF工具包DataGrid SelectionChanged获取单元格值

标签: c# wpf datagrid wpfdatagrid

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

我只是设法获得许多不同的Microsoft.Windows.Controls,并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;

然而.Value不是一个选择......

非常感谢,这让我很生气! 丹

代码少,而且有效。

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。

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<DataGridCellsPresenter>(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<T>(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<T>(v);
        if (child != null) break;
    }
    return child;
}

希望这有帮助,尊重

由于您使用&#34; SelectionChanged&#34;,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编写dtr[0]dtr["ID"]

答案 4 :(得分:1)

private void datagrid_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    DataGrid _DataGrid = sender as DataGrid;

    string strEID = _DataGrid.SelectedCells[0].Item.ToString(); 
}
