In the C# Code behind, how do you set the selected item to an item already in the control. My XAML is
So in the view model, I want to iterate through all the Items, find one, then set the control's selected item to it. How do you iterate over the items collection?

My question is identical to this one: http://www.telerik.com/community/forums/preview-thread/wpf/gridview/raddatapager-radgridview-refresh.aspx, but unfortunately, the original poster who claimed to have solved it didn't actually post what he did. :-\
I have a RadDataPager bound to
.
I have a listbox that has its ItemsSource set to:
When the underlying collection 'Bar' changes, those changes aren't being reflected in the listbox and I'm not sure why.
Any thoughts?
thanks.

How would you evaluate an expression generated by the editor without needing to pass it to the RadGridView?
Thanks!

Here, I store the contents of my RadRichTextBox in my database.
For storage I must thus use an export. And, for displaying an importation.
I use all the functions suggested by your RadRichTextBox, primarily:
- MergeField
- Tables
- Image
The concern, it is that according to the provider used, I lose one or more information, has to know:
- DocxProvider, I loses the size of the tables and I lose the style of MergeField
- RtfProvider, I loses MergeField
- XamlProvider, if I use MergeField I have an error message at the time of the importation “Boat create Telerik.Windows.Documents.Modele…”
I would prefer not to use RtfProvider, indeed, it stock the images with format BMP and that takes too much place.
Could you indicate good walk to me to be followed?

Hello
We are using the RadGridView to show hierarchical data X levels deep. Typically this is only used up until 5 or 6 levels deep.
We use the RowChildTemplate where we define other radgridviews that display the collections of children (loaded on demand)
Now, the problem is that when we expand a top level node that has a lot of items (2000+), it takes a very long time for the UI to update (> 2 mins) and afterwards the application is very unresponsive + takes up a lot of memory. I have a suspicion this is because the child gridview containing the 2000+ items is actually in the first row, of which a part is shown in the UI obviously. So even if only the top row + 2 or 3 rows of the child gridview is visible in the UI, the other 2997 rows of the child gridview are still instantiated because they are "part of" the top level row so virtualization is not used on "sublevels".
Is this a known problem and do you (or anyone) perhaps have a workaround for this? This is a blocking problem for us...

Hi,
I am using a GridViewComboBoxColumn with incremental filtering:
When I have many items in the combobox (170 in one case, 6000 in another):
1. The filtering doesn't seem to work correctly (from 8 correct elements as in the DB, it shows me 5 correct and other 5 incorrect)
2. For the big one, there are performance issues (one lettre filters in 2-3 seconds).
Have you any solution to this?
Thanks in advance,

All terminology aside, I need to know when a pane is visible to a user. And let me define visible as:
1. Floating panes are always visible
2. For panes in a tab group, the "selected" tab is visible, the rest are visible=false.
3. Pinned panes which are collapsed are visible = false. If the user clicks on them and they expand, then visible = true for that time period.
4. Panes not in a tab group, are visible=true.
I need this, as our panes have calculation engines in them which consume resources. And if a pane isn't visible, then those resources shouldn't be wasted.
Through great panes, I've written a demo which attaches to EVERY event on RadDocking. Trying to understand when things are triggered, as the documentation is insufficient in my opinion.
The attached demo project has a Pane which does calculation when calculate is set to true. So in essence, it needs to be "fixed" for the following cases (which I consider bugs, as there's no event capable of telling me of the appropriate state changes):
1. When a pane is added to a group, PaneStateChanged is called, but it's called BEFORE the state change, and not AFTER as the "ed" on Changed would imply. So the pane isn't in it's new RadPaneGroup yet, and I don't know which panes to set calculate to false for.
2. Pinned tabs. This doesn't work at all. Make a pane, dock it in the main window. unpin it so it slurps up to the top.. Now, when hovering over "pane 1", the pane is shown. .but no events are triggered on RadDocking. How am I to know to turn on calculation for the duration of the showing? Is there an event somewhere else to tell me this?
It works in these cases, though the code to do it is ghetto.
1. Changing tabs in a group. I had to bind to ActivePaneChanged, and iterate through the Parent's of New/Old Pane's tabs, and update them all for the state change. This is wasteful as RadDocking knows what I want to know internally.
And great.. I can only attach pictures here.. wtf. I'll add it to the support ticket then, and none of the lovely users of the community will be able to see it.. DUMB restriction!
