RadGridView Validation

[Denis]

We have an application that uses RadGridView.
We use RadGridView collection of objects that have attributes of validation.
There is also a button on the ToolBar that switches on edit mode of objects (editing is disabled by default).
The problem is that when you add a new object that does not pass validation and disable the editing mode, the application crashes with StackOverflowException.
If the button Edit Mode is not on the ToolBar everything works fine.

List the steps to repeat this behavior:
1) Press the Edit Mode (on the toolbar)
2) Add a new blank line (by pressing Ins)
3) Cancel the edit mode by clicking the Edit Mode (on the toolbar)
4) Click on any item on the main window
5) get the exception

If in p.3) you press the the EditMode button not on the toolbar everything will work fine without any exceptions.

Hello Denis,

Thanks for sending the project. I have made a few tests with it. Here are my findings:

In the root of the trouble there is  a setting:

CanUserInsertRows="{Binding IsEditMode}"


This forces RadGridView to enter kind of impossible state - the user can not insert a row , however we are in the middle of inserting a row.

To solve the issue you may need to either call the CancelEdit() method of RadGridView  or invoke the relevant command of RadGridView , before switching the "IsEditMode" property to false.

Kind regards,
