Insert items in edit mode problem

[Lauren Nickerson]

Hello.

As the title says, I'm trying to set a node to edit mode as soon as it's created. The approach I'm using is through WPF binding and styling. Basically, my object has a property called "IsNodeInEditMode", and I have a RadTreeViewItem style that sets this property based on the object it's bound to:

        <Style TargetType="{x:Type telerik:RadTreeViewItem}">
            <Setter Property="IsExpanded" Value="{Binding IsNodeExpanded, Mode=TwoWay}" />
            <Setter Property="IsInEditMode" Value="{Binding IsNodeInEditMode, Mode=TwoWay}" />
        </Style>

So, as soon as I insert the item, I also set its "IsNodeInEditMode" property to true, which effectively makes the tree item go to edit mode, however, when I change the name of the newly created item, and press enter, it changes back to the original name, and not what I set after creating it, you can see that in this video:

Can you think of something that might be resetting the name? I debbuged this, and checked the call stack on the Name property Set accessor, but I can't get to the code that makes this change since it's external.

Let me know. Thanks!

Hi Lauren Nickerson,

Is the new name propagated correctly to the business object? How you update the business object with the new value?

I am having this same problem!  Has anyone found a solution.  It seems like a bug.

Hi Anthony,

I tried to reproduce the reported behavior with our latest official release on our side and it seems that the code works as expected. Can you please take a look at the attached project and see if I missed something.

It will be great if you can change the code so that the issue can be reproduced in this project and send it over. By dong so I will be able to further investigate the reasons behind the reported behavior.

The attached project doesn't seem to have any way to add nodes, nor any mechanism by which they would be added in edit mode. Does it?  That was the question, as I read it (and it is my issue now, as well.)

Hello Scott,

You are right that in the previously attached project there is no way to add items in edit mode. Please note that that project demonstrates how your business object should implement the INotifyPropertyChanged interface and how the IsInEditMode property should be bound.

In the currently attached project, I implemented simple logic for adding new items in edit mode. You should create a DataTemplate that will be used when the item is in edit mode and bind the header of the item in TwoWay mode.
Also, that DataTemplate should be set as ItemEditTemplate of the RadTreeView control.

Please take a look at the attached project and let me know if you have any further questions.
