BI{code} ?

Is there any way to intercept grouping event: dragging column header on the group bar by user and pass additional parameter to controller ?

• you can use `Parent`, `Parameter`, and `ParameterFunc` grid extensions to send additional parameters https://www.aspnetawesome.com/learn/mvc/general#Binding-to-Parents

• not really, you could handle `aweload` perhaps, not sure why would you need that, please explain what are you trying to build from the user point of view ?

• I want to get following result: when user group by any of columns - pager turns off like g.PageSize = items.Count(); I have solution for grouping by user button click: <a onclick="group();" >GROUP INSPECTOR</a> function group() { $('#@gridId').data('api').load({ group: ['inspector.login'], oparams: { cmd: 'nopage' } }); } but I can't manage how to do the same without button.

  ok, so you want to turn off grouping when the user groups by any column, and you're doing this already using grid api by calling `g.PageSize = items.Count();` you can do this in your controller: if (g.Groups != null && g.Groups.Length > 0) { g.PageSize = items.Count(); }
