[Solved] Is it possible to rebind the ajax url?

[Patrik]

We have a small grid that looks like this:

@(Html.Telerik()
    .Grid(Model.Model.CommunityHelpdeskThreads)
    .Name("CommunityHelpdeskThreadGrid")
            .Columns(columns =>
                         {
                             columns.Bound(dlm => dlm.Title)
                                .ClientTemplate("<#=Title#>");
                             columns.Bound(dlm => dlm.PostCount)
                                 .Width(100);
                         }
            )
    .EnableCustomBinding(true)
    .Pageable(paging => paging.PageSize(10))
    .DataKeys(dk => dk.Add(key => key.ThreadId)))

However we can't specify the databinding at this point since the parameters are still unknown.
So we tried to add a javascript to rebind the grid but it's not working:

function CommunityHelpdeskThreadGrid_ApplyDataBinding() {
    try {


        var grid = getGrid('CommunityHelpdeskThreadGrid');
        if (grid == null) return;


        grid.ajax.selectUrl = '/Community/Helpdesk/_GetThreadsForSearch/' + parameter;
        grid.rebind();

    } catch (e) {
        alert("Error occured" + e);
    }

}

No call is being made to the server.

Any ideas?

Hello Patrik,

In order to use rebind method, grid component should be set to use ajax binding instead of server binding used in the snippet you have pasted.

The problem is that we want to avoid that it databinds before the url has been properly set. This occurs when they type something in the search field.
So i don't want the initial bind and i also don't want the users to be able to press refresh.

Hi Patrik,

You may use DataBinding event to prevent the grid to be automatically populated on initial load when ajax binding is use. 

var initialLoad = true;

function dataBound(e) {
     if (initialLoad) {
          e.preventDefault();
          initialLoad = false;
     }
}

All the best,
