I have a listbox defined in the xaml -

I frequently need to clear and repopulate the ItemsSource to refresh the Listbox. (LineItems is an observable collection). When I clear the collection, the SelectedItem is also cleared (visually). When I repopulate and set the SelectedItem object with data, there is no item in the ListBox which is selected. Below is the code -

How do I get the selected item to re-appear on the listbox after the ItemsSource is cleared?

Thanks.

Dear sir,

I am using the  Rad Masked Currency Input control in my project. One of the requirement  is  to show empty content when the value is null.

 Unfortunately, when  I set the empty Content property to string. Empty or to null , I still see the default value in the control ( zero number).

 I can see an error in the output window of problem to convert null object  to value. 

I have noticed that after pressing the clear button and opening again the control  the content become empty.

Do you have a solution to this scenario?

Thank you,

Hey everyone,

I'm currently working through some existing project, and would like to set up a RadComboBox that will complain if it doesn't have a current selection, or the current selection is an empty string. The current ComboBox is the stock WPF control, and populates itself like this:

I'm new to MVVM and WPF, and this doesn't seem standard. So, what I want to know is if there's a nice way to have the RadComboBox control complain about an invalid SelectedItem? Do I need to rip this apart and do data binding? If so, is there an example I can look at to get an idea?

As always, thanks for the help,

Hi guys,

I am currently working on a way to display data, that is structured on 3 levels.
On first level is a week, on second level a day, and on the third level a basic entry.

Based on that system I thought about the RadGridView and the Child-Relations.
My main problems now are, that I have especially on the third level way too less space in the child-table so its basically unreadable. 
Is there any way to give the childtables more space? 

The other problem is, that I haven't found out, how I could set different Templates for the childtables.
The HierarchyChildTemplate only works for one Child as it seems.

The reason why I not just Group by the Days and weeks is, that I later want to use Drag and Drop entries between the days. 
I thought this would be more possible in a hierarchical system.

I also tested the RadPanelBar, but there I would need to create somethin like a table with frozen headers and so on manually.

Greetings,

Hello,

I am using a Docking-Layout in my Application with some RadPane's in it. Each RadPane is bound to a different ViewModel. When the RadPane is visible, everything works as expected.

But I struggle with some Binding Errors when the RadPane is hidden on start up of my application. Is there a way to reset/update the DataContext of the RadPane when the PaneStatus changed to visible?

I can provide a code example if you want.

Cheers!

I'm trying to spread out the items in my carousel so there is a bit of space between them (and ideally no change in z depth as they animate).

It seems like the items can only spread out to the edges of the screen. In my case I need 3 landscape images visible at once.

Instead of overlapping 3 images on screen like |[--][--][--]| where the center image is raised/focused, I'd like [-|-][--][-|-] where the side images are the same size and partially off screen.

I've tried the following, as well as using bezier curves with control points, etc.

<Path x:Key="horizontalPath" Stretch="Fill">
  <Path.Data>
     <LineGeometry StartPoint="-1000,0" EndPoint="1000,0" />
  </Path.Data>
</Path>
