Removing ItemPropertyDefinitions at runtime

[Saravana Kumar]

Hello,

I'm using the RadDataFilter in unbounded mode. I'm struggling to get this functionality working. The requirement is once the user has filtered on a particular property, then I need to remove it from the list so the user can't filter on the same property again.

I'll give an example. If the employee object got 3 properties (Name, age and dob), the use has selected "age > 30", then age should not appear in the list anymore.

There are only couple of events exposed on RadDataFilter (EditorCreated and FilterOperatorsLoading). I tried to do something like this in the EditorCreated event handler

            this.radDataFilter.ItemPropertyDefinitions.Clear();
 
            foreach (var item in AvailableProperties)
            {
                this.radDataFilter.ItemPropertyDefinitions.Add(new ItemPropertyDefinition(item));
            }

but the "Clear()" method on ItempPropertyDefinitions throws an HRESULT COM exception.

I kind of reached a brick wall, can you please confirm whether its possible to implement this.

Regards,
Saravana

Hi Saravana Kumar,

Unfortunately, this would not be possible with the current version of RadDataFilter. To be honest, I don't think that we will be able to develop similar functionality, since the architecture of the control will not allow it. Thank you for your understanding.

This is kind of show stopper for us, is there any dirty solution to get away fromt this?

Hi Saravana Kumar,

I understand your requirements, but such behavior was never part of the control specification and functionality.

I am afraid that there is no "hack" that can help either. Thank you for your understanding.

I need the same behaviour in my project. Is there already a way to do this?

Hello Lilia,

As I have already mentioned, this behavior was never part of the control design and I seriously doubt that it will ever be.

Kind regards,
