[英]WPF Toolkit DataGrid SelectionChanged Getting Cell Value
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
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。
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,问候
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。
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。
private void datagrid_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
DataGrid _DataGrid = sender as DataGrid;
string strEID = _DataGrid.SelectedCells[0].Item.ToString();
}
