Hi,
We are using XAMComboEditor and want to add check box as top Item in XAMCombo Editor , so as we checked this checkBox all Items should be select.
Please let us aware about select All check Box.
Thanks
Hello Kanwar,
The shared XamComboEditor does not have a SelectAll checkbox feature. To work around this I recommend creating a user control and add a wpf Checkbox somewhere above the combo and handle it's Checked/Unchecked events to add logic which toggles the IsSelected items for each item otherwise it clears the items from the SelctedItems collection.
eg.
private void Select_Deselect() { foreach (var item in combo.Items) { item.IsSelected = true; } } private void CheckBox_Checked(object sender, RoutedEventArgs e) { Select_Deselect(); } private void CheckBox_Unchecked(object sender, RoutedEventArgs e) { multiChbCombo.SelectedItems.Clear(); }
Otherwise you'll have to modify the default style for the XamComboEditor. This was explained here:

Please submit a new product idea to have this features added at ideas.infragistics.com
Let me know if you have any questions.
Any way to increase performance? When I have 900+ items in the combo, CheckBox_Unchecked is instantaneous, but CheckBox_Checked takes 15+ seconds.

Answered my own question:
var list = (List<CheckedName>)combo.ItemsSource; combo.ItemsSource = null; combo.SelectedItems.Clear();
foreach (var item in list) item.IsChecked = true;
combo.ItemsSource = list;
