I am using the MVVM pattern (with MVVM light) and have a Telerik TabControl bound to a collection of ViewModels like this:


The ReviewViewModels collection is an ObservableCollection<object> because I have one static tab along with any number (generally 2-3) of user-selected tabs based on items selected in another window. Since the ViewModels are drastically different I had to be as generic as possible for the root collection and then use a ContentTemplateSelector to show the appropriate content.

The issue I have is occasionally one of the tabs is duplicated, even though the underlying source doesn't reflect this. It's very intermittent, but I just happened to catch it on my screen while working on something with the app (Phase I is still in development) and the screen showed four tabs (one was a duplicate) and when I hit a button on the view to catch in a breakpoint I could see the underlying collection only contained three total items (which was expected). I can't seem to figure out where this other item is coming from as when data retrieval is complete for the tab content I explicitely instantiate the collection at that time and loop through to add the items like this:

Any suggestions on this as to where to even start looking? I am using Q2 2011.

Edit: It just happened again and the interesting thing is the fourth tab (the duplicate) is selected even though (as indicated above) I set the selected index to 0. I hit a button on the view that takes me to the VM and did a couple of screenshots showing the data is correct:

http://www.clearsolgroup.com/images/immediate-window.png (Immediate Window - shows three total ViewModels [expected] and SelectedIndex is 0)

http://www.clearsolgroup.com/images/duplicate-tab.png (UI of the duplicate tab, with the fourth being selected even though SelectedIndex is 0 and only three ViewModels exist).

Again, this is VERY interimmittent and reproducing it is intentionally possible. It just happens occasionally.

Hi,

I am trying to do a ElementName binding in CellTemplate, however when I follow the solution on this page
http://www.telerik.com/help/wpf/gridview-troubleshooting-elementname-binding.html
The example code doesn't work. 

Can you take a look?

Hi,

  Is it possible to use a spline line and a step line in a TimeBar.

Hi,

Reviewing the documentation and samples, I've noticed two different ways of associating a legend with a chart area. Given I have defined:


I can either associate with a chart area with LegendName:


or bind it to the Legend property:


Which is the preferred way to associate a chart legend? Are there advantages/disadvantages with either way?

Kind regards,
Dave.

Hi,

I want to create special rows that have only one column (i.e. column span for a specific row).

So I created ControlTemplate with that single column, created a Style that change the template property to the new template and created RowStyleSelector that uses that template when needed. That worked but created a row that doesn't have the IndicatorPresenter at the start of the row.

You can see the picture.. 

Can I merge cells at the grid and stay with the default template?

Or how can I make sure that the IndicatorPresenter will appear with the same styles.

I would like to generate the charts without actually showing it (in a WPF application), and then save them to image.

However, when I run, I hit  the InvalidOperationException

Hi,

just was playing around with the new image editor. i'm using a custom ui like the one in the demo (the one with the image of the baseball player) and i was wondering if there is a way to set the height and width of the cropping rectangle to a specific size.i want to force the user to crop his images to a predifend size or at least aspect ratio. similar to the way you assign contact images on a iphone.

and one more question, how can a write the RadBitmap to a byte array for storing it in a DB?
UPDATE: OK, forget about the DB thing, just found the

Telerik.Windows.Media.Imaging.FormatProviders.BmpFormatProvider 

best regards

Hi Telerik,

When using RadSchedueView, I'd like to use the predefined category list and assign a category to the appointment dynamically. This list is defined in RadScheduler. When I added these two references, it had name conflicts. How can I use this predefined list in ScheduleView?

Thanks.

I am trying to make multiple changes to an observablecollection that is bound to a gridview.
Using linq to locate the items and then making changes.

It seems to work because I loop through in break mode and see it meeting the condition and setting the items Status value for the exact count of items that I am searching for, but I am not seeing changes reflect in gridview that has itemsource of the collection.


I assume since the collection is bound to the grid's ItemSource that it would update the grid automatically... does there need to be a manual update after the update takes place?

Is there a better approach for performance or clarity reasons?
