I posted a similar question and the problem could not be replicated. I also though it might have been the workstation and all the libraries, controls, et. al. installed on the machine.
Problem exists with a new Windows 10 workstation. Using Infragistics ASP.NET 2017.2; controls used in set Infragistics45.Web.v17.2, Version=17.2.20172.2095
This is the problem (see image) - created a web application in VS 2017. Open a new Web Form and place a WebTab on the form. Expand the webtab to almost the size of the screen and you can see a blank footer / empty space at the bottom of tab. Nothing done removes or resizes this dead area.

Thank you for posting in our community.
I noticed that the service release that you are using is not the latest one for version 17.2. At this point, the latest SR available for download is 20172.2123. Can you please try downloading the latest version and let me know whether you are still experiencing the same behavior?
The latest version can be downloaded from our web site. You need to log in with your credentials and navigate to "My Keys &Downloads" section. Click the product of your choice and under "Service Releases" tab you will find all service releases for this product
If you need any assistance do not hesitate to contact me.
Looking forward to hearing from you.
Upgrade to the latest version and the results are exactly the same. Instead of using the existing application, created an empty project and added to web tabs (inside a DIV and another outside); the results are the same and there is still a footer - I cannot get the tab to be the size of the actual tab container. Here is the source for the form:

Designer View with the footer:
Thank you for your patience while I was looking into this matter for you.
I created a sample, using version 17.2.20172.2123 and the code snippet provided. While in Design vie in Visual Studio I noticed the behavior from your screenshot - the tab container is not expanded to the entire pane, However, later, when I run the app in Chrome browser tab content was displayed as expected occupying the entire space without any footer. For test purposes I put a div with red background color in the tab pane in order to demonstrate that there is no footer left under the tab content pane.
I was wondering whether the issue, from your point of view, is that there is an empty space in Design mode in Visual Studio or you are having the same empty space when the WebTab is rendered in browser?
Attached you will find my sample for your reference. Please test it on your side and let me know how it behaves.
Looking forward to hearing form you.
In both the sample and production application, at run time, the space is not "visible" but still effectively removes that space from use. I have a grid in the tab and that anomaly prevents the grid from growing without having that space visible and the page has to be enlarged to see more detail. Not sure how I can reclaim the additional space on the screen.
Can you please modify my sample in order to match your scenario and send it back to me along with steps to reproduce. Having a working sample, illustrating the issue, is going to be highly appreciated and will help me investigate this matter further in pursuit of the root cause of this behavior.
I was able to use your sample and another sample and replicate what you described: even though there is a "footer" space that is fixed in designer, at run time the space is adjusted and there is no longer that footer space. The only difference than these samples and the application first seen is that none of the objects in the samples have position as Absolute - the spacing is Relative by default.
I will work with the samples and change those properties to see of that is also enforcing the spacing issue.
This could be the reason. Also make sure there are no additional styles applied, which are causing this.
Looking forward for your findings.
