Paging vs. grouping

[Petar Raykov]

Hi guys,

I’m trying to implement the following use case:
I want to have a grid with paging and grouping. That’s ok and works. When I group the elements, I see only the grouping inside the single page. I have to implement a mechanism that deactivate the paging, when the groping feature was used.
I’m using the JSON Action mode.

Hier is my controller:

public ActionResult Table()
{


GridPropertiesModel gridModel = new GridPropertiesModel()
{
Caption = "Orders",
AutoFormat =
Syncfusion.Mvc.Shared.Skins.Office2007Blue,
AllowFiltering = true,
AllowGrouping = true,
AllowPaging = true,
ActionMode = ActionMode.JSON
};


ViewData["GridModel"] = gridModel;

return View();
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Table(Syncfusion.Mvc.Grid.PagingParams args)
{
GridPropertiesModel gridModel = findTheGridByID(args.ID);
gridModel.AllowPaging = false;


List data = getList();

return data.AsEnumerable().GridJSONActions();
}

Any ideas how to implement the function findTheGridByID(string id)?

Kind regards,
Petar Raykov

Hi Petar Raykov,

Thanks for using Syncfusion Products.

We suggest you to use OnActionBegin ClientSideEvents for your requirement to deactivate paging when grouping is enabled. Please refer the below code snippet.

[Controller]
GridPropertiesModel model = new GridPropertiesModel()
{
Caption = "Orders",
DataSource = OrderRepository.GetAllRecords(),
AutoFormat = Syncfusion.Mvc.Shared.Skins.Office2007Blue,
AllowFiltering = true,
AllowGrouping = true,
AllowPaging = true,
AllowSorting = true,
ActionMode = ActionMode.JSON,

};
model.ClientSideEvents.OnActionBegin = "ActionBegin";

[JavaScript]


For your convenience, we have prepared a simple sample to demonstrate this and the same can be downloaded from the below link.

Hi,

thank you for your responce. The way you suggested is super. Unfortunately the example (and the code in your post) doesn't work with IE9 and Firefox 11.

When i drag the group to the grouping place 2 POST-requests will be maked:
1. args.requestType == "grouping"
2. args.requestType == "paging"

The first is ok, but the second cuts my result to size of one page.
