A quick search tells me no, at least not with the standard Xojo WebListbox. But checking with you all?
I have a WebListbox with several columns, requiring scrolling to the right. Column 0 is the assignment name, and the remaining columns are student names with their assignment completion percents. I’d like to lock column 0 in place so when I scroll to the right to view the last student column, I can still see the assignment name. Possible?
I don’t think this is offered for DesktopListbox either, right?
As WebListbox is based in DataTables you can open a Feature Request to add fixedcolumns, if there is not a request already.
Looks like there are two similar Issues already created, so I did not create a 3rd
https://tracker.xojo.com/xojoinc/xojo/-/issues/56090
https://tracker.xojo.com/xojoinc/xojo/-/issues/33943
Created 5+ and 10+ years ago, respectively, and both now have a “Needs Review” tag thanks to Xojo Bot. I gave both a thumbs up. Will deal without for the time being. Hopefully these will get some attention
I would create new request though, obviously the 5 and 10 yrs old requests are no longer pertaining to the newest Xojo. Btw, fixing first column and making the column divider red or some other user defined color would be nice.
Creating new requests for existing requests just clutters the system.
If it’s 5-10 years old, that means Xojo doesn’t have an interest in the request and you should investigate workarounds.
FWIW, 2025r1 comes with a few Feature Requests filed 14 years ago. Please upvote the relevant cases, it is one of the best signals of interest.
Did this yesterday! Hope others will also thumbs up these cases to get this feature approved for production
I disagree.
A staff member literally told you to upvote relevant cases as those are better signs of interest than creating clutter. If you create duplicates @Robin_Lauryssen-Mitchell has to spend time looking for the original and then closing yours.
Edit: Not to mention that outside sources use the ballooning open ticket count as reasons Xojo is struggling. You want to contribute to that evidence? Because you don’t know how the system works? 
Well, Xojo is a product and relies on money spent by people who use it aka “customers”. If it takes 10 tickets to signal interest in the feature/bug so be it. It is nothing personal nor any indication of company being weak, rather it is an indication of having vibrant user base.
Btw, I don’t need to know how the Xojo internal system works, this is “black box” to me and it better stays this way. I appreciate the effort made to make Xojo better and it is all that counts to me. Thanks.
