RadGridView crashes when I filter a column with integers

[Hadrien]

Hi,

I have a RadGridView with many column and in all of them I can filter data using the popup window (see attached gridview.png). In one of the columns, which has integers as data source, when I tick one of the available options it works fine, but when I use the filter "equals to" and I set a number my program crashes (see error.png). It's curious because I noticed that if I first select one of the others filters first ('is greater tham', 'is not equal to', ...) and them select the 'is equals to' it works!

Do you know what can be the problem?

Hi Hadrien,

I've tried to reproduce the problem you report, but to no avail. I have attached my test project for a reference.

I'd just mention that I experience this too (I didn't check your work-around though).

The error is not reproducible in the example provided by Yoan.  However, I was able to get a stacktrace using my own application (of course I will try and recreate this by modifying the example provided by Yoan)

Hi Robert,

Such error is not reproducible on our end. Can you please try reproducing it with the sample application provided by my colleague? If you manage to do so, you can open a new support ticket and attach it there. We will be happy to help.

All the best,

I think this might be a race condition during initialization.  My data set is big enough to cover a couple of screens.  The data is loaded into an ObservableCollection using EntityFramework 6.  Here I suspect properties might be initialized from a background thread which could cause problems if you are not using normal Bindings (which marshall some property changes to the UI thread) but have your own INotifyPropertyChanged.PropertyChanged event handlers.  Do you guard against events from other threads in your event handlers?  If not, that might be a good idea so that the source of such errors becomes easier to find.  Library vendors like you should use design-by-contract (in some form), so that your users can code more and debug less.

 

On a side note, I am not too happy with EntityFramework modifying properties from background threads, it has no reasons to do that at all; but I know it does anyway.

[Ivan Ivanov]

Hello Robert,

I reviewed the code that is behind the stack trace that you mentioned. This really looks like a possible race condition. However, looking through the logic that must be responsible for this behavior, I don't seem to find when an unnoticed propertychanged occurrence can break it. Generally, the filtering data engine initialized an implementation of FilterOperatorExpressionBuilderBase in accordance to the column type. Then the same descriptor is used to chose the operator part of the filtering logic. However, in the described scenario, it seem that the wrong factory gets picked. Its type does not implement the mentioned method (Contains is supporterd only for string and IEnumerable<T>) and the exception is thrown. I must be missing something.
Can you please shed some more light on the scenario, so that I can be more precise, while trying to reproduce it. I guess that exception is thrown when the filter is applied and the filtered type is string? Are there any items in RadGridView at the time when the filtering popup is opened? Can you please try fixing the column's data type to string to check whether the issue is still reproducible.

Regards,
Ivan Ivanov

[Robert]

Hi Ivan,

How is the column type resolved?  

I use a GridViewDataColumn and have taken no measures to disclose the source type.  The source type is in one of the cases a "long?" and another is "int?".  As the source type suggest some of these might sometimes be null.

The ItemsSource is in one of my applications of RadGridView a CollectionViewSource with the Filter event handler is permanently set.  Perhaps it confuses the filtering in RadGridView that the ItemsSource is itself a CollectionViewSource?

But really, I have no clue, because I don't have the Telerik source code.

What kind of races do you believe you have found so far?

[Ivan Ivanov]

Hello,

Would it be piossible for you to hadcode the DataType property of GridViewDataColumn to int? and check whether the issue is reproducible? I believe that this can guide us into the right direction. The stack trace shows that the failing filtering operation is "Contain", which should be available only for the string and IEnumerable<T> types, so thisis quite unusual.

Hello,

 

I Have a RagGridView being populate by a Dictionary with strings and Objects. When I want to use the filter tab on my program the option "greater than " "less than" don't show to me. I don't know if this can be do by a dictionary or others. Somebody could help me ? Please?
