Adding a 'Does not contain' filter operator

[Rick Glos]

Hello,

Clicking on the filter icon only allows for 5 comparisons (what I think are termed filter operators) on string column:

 

Is equal to

Is not equal to

Starts with

Contains

Ends with

 

I don't see a 'Does not contain' which is the opposite of Contains.

Is this something I could add easily to the existing filter mechanism or do I need to go to a fully custom filter as shown via your demo of custom filtering?

Hello Rick Glos,

Currently we do not have such a FilterOperator, but I will log your feature request. Until we develop it, you can create a Custom Filtering Control which will add/remove special IFilterDescriptors to RadGridView's FilterDescriptors collection.

Your implementation of the IFilterDescriptor interface should create a filter expression to do the "Does not contain" logic.

To learn how to create such a custom control, please refer to my blog post Custom Filtering with RadGridView for Silverlight.

You can see the implementation of another two custom filtering controls in our online Custom Filter Controls example.

Kind regards,

It's been 6 months and our client is still asking for this.

You mentioned you logged the feature request.  Is there any update?  Is this on the radar or far down the list of things you might do soon?

If not, it looks like I might have to proceed with custom filtering.  Is this still the preferred approach?  I cannot simply create a custom filter expression, but I must customize the entire filter control and replicate the existing filter expressions and then add my new one?

Hello Rick Glos,

Please excuse us for the inconvenience. This feature has been unable to make it for a release. I will escalate this issue to our developers right away and I hope that we will have it released next Friday with the Latest Internal Build. Will this be ok?

Once again, accept our apologies.

I think that would be excellent.  Thank you.

Hi Rick Glos,

We have added the DoesNotContain filter operator and it will be available in the 2010 Q2 BETA version we are about to release later today.

Let us know if there are problems after you upgrade to it.

Best wishes,

Hi Team,

We are using Telerik.Web.Mvc.dll of  File version : 2012.1.214.340 and Product version : 2012.1.214.340 .

We didn't find “Does not contain” filter property and telerik grid tooltip property in this version. And our client wants to add these features  .

Can you please let us know “Does not contain” filter property is supported in Telerik File version : 2012.1.214.340  if not then in which version it will be available ?

Please help.

Regards,
