listbox

问题 The following shows me 3x "MultiTest.Model.Customers" in the ListBox (one for each record it should display).

问题 So I have a listbox and a class. This class is called 'Mission' and has three properties: Name, IsStarted and IsCompleted. I have used a BindingList and set the datasource of the Listbox to that BindingList. This works fine, no problems so far. What I don't know how to do (and I hope it's possible) is to bind the properties IsStarted and IsCompleted to two CheckBoxes, so that if I change which Mission is selected, those CheckBoxes will change to reflect the properties of the SelectedItem. I

问题 In my WPF application, I have a simple listbox: <ListBox x:Name="lbUtilities"> <ListBoxItem Tag="2" Content="One" IsSelected="True" /> <ListBoxItem Tag="5" Content="Two" /> </ListBox> The problem is that when the ListBox appears first time, the selected item ("One") is not highlighted. If I click on any item, it gets highlighted. How could I have the selected by default item to be highlighted to the system color? Thanks. 回答1: It is selected but you need a hightlight for not focused <ListBox

问题 I need the requirement that.. Initially i have set of datas that are bound to ListBox... If we scroll to the end i will add some more datas to the collection and will update the ListBox... Is there any way to achieve this in Windows phone ? 回答1: I suppose that by "achieve this" you mean the possibility to detect if the ListBox is at the end. In that case, this should help. You'll first need to gain access to the ScrollViewer control in order to see if a user scrolled, and what the current

问题 My question is similar to this: How to prevent ListBox.SelectedIndexChanged event?, but I want to ask it a different way. Is there a simple way to determine if the 'SelectedIndexChanged' is coming from the user as opposed to initiated through code (e.g. ListBox.SelectedIndex = x)? 回答1: As far as I know, no, there's no simple way built-in. The best I've been able to do is set a flag just before changing it in code and then letting the event handler reset the flag and return. I suppose you

问题 I have created a Listbox in WPF, where I plot 2D points randomly when the user clicks Generate. In my case I'm going to be plotting several thousand points when the user clicks Generate. I noticed when I generate around 10,000 or even 5,000 points, it takes forever. Does anyone have advice on ways to speed this up? Is it possible to only trigger the update to take place once all points have been generated, assuming that due to the ObservableCollection it's attempting to update the listbox

问题 I'm making a touchscreen interface that uses a listbox. I have a button above and below the listbox for page up/down.
