Select whole column by clicking ColumnHeader. WPF DATAGRID
提问by MajkeloDev
I have a data grid which has disabled sorting. What I want to achieve is - by clicking a column header I want to select all cells in this column(select whole column). I've added EventSetterto my DataGridColumnHeaderto bind some method to Clickevent, but I have no idea how this method should be written. Any ideas?
我有一个禁用排序的数据网格。我想要实现的是 - 通过单击列标题，我想选择该列中的所有单元格（选择整列）。我已经添加EventSetter了DataGridColumnHeader将一些方法绑定到Click事件的方法，但我不知道应该如何编写这个方法。有任何想法吗？
My code:
我的代码：
private void columnHeaderClick(object sender, RoutedEventArgs e)
{
var columnHeader = sender as DataGridColumnHeader;
if (columnHeader != null)
{
if (dgDane.SelectedCells != null)
{
dgDane.SelectedCells.Clear();
}
foreach (var item in dgDane.Items)
{
dgDane.SelectedCells.Add(new DataGridCellInfo(item, columnHeader.Column));
}
dgDane.Focus();
}
}
I Edited the code, this one above works fine(thanks to @nit). I've added focus to DataGridbecause it was necessary.
我编辑了代码，上面的这个工作正常（感谢@nit）。我添加了焦点，DataGrid因为它是必要的。

This should do the trick
这应该可以解决问题
private void columnHeaderClick(object sender, RoutedEventArgs e)
{
var columnHeader = sender as DataGridColumnHeader;
if (columnHeader != null)
{
dataGrid.SelectedCells.Clear();
foreach (var item in dataGrid.Items)
{
dataGrid.SelectedCells.Add(new DataGridCellInfo(item,columnHeader.Column));
}
}
}
Make sure you set SelectionUnit="Cell"on DataGrid
请确保您设置SelectionUnit="Cell"上DataGrid
<DataGrid x:Name="dataGrid" AutoGenerateColumns="False" IsSynchronizedWithCurrentItem="True"
SelectionUnit="Cell" />
