This doesn't work on boolean columns. We have data that supports true/false/null, and we can only get true and false to work. If we try and include a null filter option, the grid filter just assume false and null are the same. See support ticket, https://www.telerik.com/account/support-tickets/view-ticket?threadid=1133790, for details. I'd expect this feature to work for all column types.

unable to filter with null values in kendo grid...When can we expect this feature

I was surprised to find out that this feature was not standard. This should be a high priority add to the next release.

Is this definitely being included by the end of the year? This functionality is a deal-breaker for us, and if it isn't going to be available, then we need to find a different solution.

we need this feature ASAP. Thank you.

The KendoUI Q3 Roadmap was just announced and the #1 most-voted-on suggestion is still marked as 'Under Review' (since May of last year).  It's beyond frustrating -- can you give us anything more specific than "It will be pondered in the second half of 2015"?

We need this for our data reporting.  Please add.

that's a must!! please add this 

This should be the very basic and mandatory feature to be available in Kendo. It will be great if we get this soon..

I have just found that I need this feature for client side filtering. Non-blank. Let get this thing rolling.

Please we need it !!! 475 votes is not enough?

I would be eternally thankful (in my heart not in my pocket) for the addition of null filters.

We are need it!!!!

The most annoying issue in the grid.

We need it.  Otherwise we have to create custom views just for blanks or nulls.

Any traction on this?!  I get nagged on a consistent basis that this functionality isn't present in our site.  Love the grid component, but this is a big hole in functionality.

I was surprised to see this feature not there! Re-creating Dynamics CRM like grids and need this feature.

Add me to the list of people requesting this feature - just got a request from our product owner that users want this functionality in our applications.

Back in April 2013 I got this response from the Kendo team.

"Unfortunately this [Filtering blanks/nulls] isn't something trivial and is not an often required feature. In fact, across all of my years here at Telerik I have yet to hear about a request to filter by blank entries across any one of our UI component suites."

At the time I was astounded. However, over the last 12 months it's somewhat reassuring to see so many people are now asking for this as my clients have been complaining about this missing functionality for ages.

Hi Guys, This is something that we also require, it would be very useful for us.

Have just run into a problem specifically because the grid doesn't support this. Really really want to see it in the near future!

Please add this filtering functionality - it's an absolute necessity.

standard filtering is limited with out being able to filter on null/not null and empty/not empty. 

Trying to migrate from RadGrid to Kendo and this is a MAJOR omission - it really is a very common ( and necessary) feature and should definitely be added as a standard feature to the Kendo grid.

Kenshin, Is there a workaround or alternative way to achieve this.?

Being able to filter on null values is fundamental for many use cases. Its very disappointing to find the grid does not allow this

How many versions have kendoUI already launched? I can't believe this functionality is still not available !!. This is something really needed.

i wonder how many votes u guys needed to add this? isn't a common sense to add this feature - if u r building a professional tool...or u guys not capable to add this feature?

I would love to see this feature make it into a release.  Requests to filter for entities with empty attributes comes up often

This functionality should be essential feature of Kendo grid. We really need this feature.

I think, this functionality is required in most cases So it should be filtered either null or not null 

This feature is "must have", especially search for NULLs. While search for NOT NULL can be workarounded sometimes, e.g. Dates, numbers.

I think this functionality is required for most of the scenarios. Anyhow, I've acheived Blank filtering by making some changes in server side dyanmic query and client side functions.

How many votes are required to include this functionality ?

This is a critical need for our implementation.  The users need the ability to find specific fields which need to be populated and the inability to search on blanks with the toolkit is causing us to have to consider alternative solutions.

What is needed is a way to easily search all columns all data on the client or on the server. A demo or a built in addition would be great.

This is an essential feature for us. Can you please add this capability as soon as possible.
