[Solved] Custom Paging with RadGrid

[Kashif]

Hi,

Can anyone please share some sample code on custom paging for RadGrid in n tier architecture.

Right now I bind grid like this:

List<User> users = User.GetAll();
myGrid.DataSource = users;

What "options" do I have to add my "GetAll" method to allow paging, sorting, filtering etc. And which events of RadGrid I have to catch for such functionality. Thanks,

Kashif

Hi Kashif,

You can refer to the following demo where you will find an example of Custom paging, grouping & filtering on 100000 items using NeedDataSource in a grid. In the example you can find that the grid is bound using an object collection.

Hi Princy,

I have a question about the Custom Paging with NeedDataSource. I had implemented just like the example in there. I see when there is a filtering, in the example, it do a Fetch of all the data, right? If this is correct, the RadGrid do a internal fetch for those records it matches, right? My question is, those records that it doesnt matches stay somewhere in memory or it clean it up? My question comes for the situation of having 2-3 millions records and I dont want them filling memory. Please let me know. Thanks,

Josue
