charlestondating com - Wpf listbox selecteditem not updating
Each action should be pretty self-explanatory and the C# code used is fairly simple, but if you're still in doubt, try running the example on your own machine and test out the various possibilities in the example.The List Box control is much like the Items Control and several of the same techniques can be used.
If you want to change the appearance of a List Box Item when it is selected, you have to bind the Is Selected property of the List Box Item. Moreover, when I click to another list Box Item, it doesn't unfocus the previous selected one.
But this is a bit tricky, you have to use a relative source with Find Acestor to navigate up the visual tree until you reach the List Box Item. i want to bind the data which is retrieved from the database onto listbox. Then it is impossible to see which item is actually selected, and impossible to get the Selected Index value. @rajasekar: The item template is used to create visuals (controls) for each data item in the list box.
In the constructor of the window, we initialize a list, add three TODO items to it and then assign it to the Items Source of the List Box.
The combination of the Items Source and the Item Template we specified in the XAML part, this is all WPF need to render all of the items as a TODO list.
As mentioned, a key difference between the Items Control and the List Box is that the List Box handles and displays user selection for you.
Therefore, a lot of List Box question revolves around somehow working with the selection.The List Box control is the next control in line, which adds a bit more functionality.One of the main differences is the fact that the List Box control actually deals with selections, allowing the end-user to select one or several items from the list and automatically giving visual feedback for it.This can be done either programmatically, as I do in the example, or by the end-user, by holding down [Ctrl] or [Shift] while clicking on the items.For each of the buttons, I have defined a click handler in the Code-behind.Please notice the Horizontal Content Alignment property that I set to Stretch on the List Box.
