Hi All,
I have a Combobox in SL App when I remove item from the collection
(ObservableCollection<UserDTO>/List< UserDTO >) work fine, but the issue
that Combobox not update its items-Containing area when its bind with
ObservableCollection, mean if there were 4 items in Combobox then will
remain 3 but total space of items-Containing remain 4. And but when its bind
to List<> then it only delete the item from collection but not from Combobox
area, mean if there were 4 items in Combobox then will remain even 4.
why, here is some code:
XAML:
<ComboBox x:Name="ddlUser" Canvas.ZIndex="2" Grid.Row="0" Grid.Column="1"
DisplayMemberPath="name"
ToolTipService.ToolTip="Select user."
Style="{StaticResource NormalDropDownListStyle}" />
CS:
private ObservableCollection<UserDTO> resultUserDTO = new
ObservableCollection<UserDTO>();
private List<UserDTO> resultUserDTO = new List<UserDTO>();
also why should I use List<> over ObservableCollection.?
Enen though I call this like,
ddlUser.UpdateLayout();
ddlUser.SelectedItem = innerUserDTO;
Thanks & Regards,
