Grid control basic features

The Awesome Grid control for ASP.net Core and MVC is used to display data, by default using a table, but that can be changed. Documentation

It can get the data from the server by specifying the url Url(urlstr) or from a js function DataFunc(jsfunc) (the javascript function could also do an ajax request and return the promise).
The Grid (like most awesome controls) can be bound to other controls using the Parent extension (used for filtering). It can also be filtered using the api.
Mods are used to add additional features to the grid like: inline editing, automatic columns hiding and via dropdown, adaptive pager (based on window width), and more.

Features:

Sorting (multiple and single column), Grouping
Resize, reorder, hide and show columns (using columns selector mod or api)
Persistence - save columns state, current page and collapsed groups/nodes
Filtering
Custom formatting
Client side api
Tree Grid
Nesting
Hierarchical grid (done using nesting)
Inline Editing (using mod)
Multiple rows group headers
Reorder rows, also from one grid to another
Frozen Columns, on the left and right side of the grid
Selection
RTL Support
Responsive layout, and autohide columns (using Autohide mod)
Custom rendering
Infinite scrolling
Cards View (using custom rendering mod)
Client data source - get data from a js function instead of specifying url
Export to excel, pdf, txt (csv) - demo
