Close groups and disable paging dynamically.

Title:

BI{code} ?

Hello, when i group by column with api: $('#@gridId').data('api').load({ group: ['columnname']}); I would like to disable paging for grid and close all groups except first. Attempts to use: $('#@gridId').data('api').load({ group: ['columnname'], params: {Paging: false}}); give no result. Thank You.

  here's what you can do, add a parameter to your action, example: public ActionResult GetItems(GridParams g, ..., string cmd) and set the `PageSize` to max when this parameter has value: var list = Db.Lunches... if (cmd == "g1") { g.PageSize = list.Count(); } for collapsing we'll need to set the `GridModelBuilder.MakeHeader` var firstGroup = true; return Json(new GridModelBuilder<Lunch>(list, g) { ... MakeHeader = gr => { // get first item in the group var first = gr.Items.First(); // get the grouped column value(s) for the first item var val = string.Join(" ", AweUtil.GetColumnValue(gr.Column, first).Select(o => o.ToString())); var collapsed = !firstGroup && cmd == "g1"; firstGroup = false; return new GroupHeader { Content = string.Format("{0} : {1}", gr.Header, val), Collapsed = collapsed }; } }.Build()); and you can call the api like this: $('#Grid1').data('api').load({ group: ['Person'], oparams: { cmd: 'g1' } }) note I'm using `oparams` (one time) with params the `cmd` will persist in the subsequent calls
