public static object GetElementFromPoint(System.Windows.Controls.ItemsControl itemsControl, Point point)
{
UIElement element = itemsControl.InputHitTest(point) as UIElement;
while (element != null)
{
if (element == itemsControl)
return null;
object item = itemsControl.ItemContainerGenerator.ItemFromContainer(element);
if (!item.Equals(DependencyProperty.UnsetValue))
return item;
element = (UIElement)System.Windows.Media.VisualTreeHelper.GetParent(element);
}
return null;
}
private void Datagrid_PreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
var item = GetElementFromPoint((ItemsControl)sender, e.GetPosition((ItemsControl)sender));
}
或者系結的是DataTable
private void DataGrid1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
DataGrid datagrid = sender as DataGrid;
Point aP = e.GetPosition(datagrid);
IInputElement obj = datagrid.InputHitTest(aP);
DependencyObject target = obj as DependencyObject;
while (target != null)
{
if (target is DataGridRow)
{
//var s = this.dataGrid1.SelectedItem;
DataRow row = (this.dataGrid1.SelectedItem as DataRowView).Row;
if (row != null)
{
UInt64 ukey = Convert.ToUInt64(row["ukey"]);
byte[] content = SqlExManager.GetDpuProtectContent(ukey, _dpu.ThisInpC.Sqlmodel);
if (content != null)
{
ProtectTemapDll.ProtectTempClass.OpenProtecTemp(content, false);
}
else
{
MessageBox.Show("查詢不到資料");
}
}
}
target = VisualTreeHelper.GetParent(target);
}
}
