Hey there guys, I've spent a good amount of time looking through other people's issues for this problem and haven't found it addressed yet.
Basically the problem I'm experiencing is trying to create an extension method to HtmlHelper (which works fine), but for some reason setting up corrected operators on filterable is causing issues. Here the code I am trying to use:
I can see the UI responding to the Extra(false) piece, but not to the ForString() piece (still just seeing the default string operators). I also see the same behavior when I apply it directly to a grid like this:
The only time I do see it working is with a row level filter such as this:
I have tried setting the GridFilterMode to menu, but that didn't cause any change. And I'm using the latest release of Telerik.UI.for.AspNet.Core (2017.1.118), the project type is .NET Core with .NET Framework, and it is using similar code to a .NET Framework project that currently works fine. Is this functionality that is no longer supported or is there a new way to implement it that I am missing?
Thanks for the help.
