Going through and testing the Kendo grid functionality. I created a new Telerik project using the menu and grid template.
.NET Core 3.1
I can get my test data to load on the grid no problem, however when ever I enter text in the search box, it gives an "Input string was not in a correct format" exception on the server side. I've noticed, that if a defined column is bound to a string typed property, the search filter works fine. But if I have a int (or DateTime for that matter) typed property, that's when I get the exception. For example, in my object I have an ApplicationId property. If I exclude it in the .Columns definition of the grid, everything works fine, however if I include it, that's when the ToDataSourceResultAsync() method seems to choke, and I get the exception. Probably something dumb, but I can't seem to find what I could be doing wrong.
