RadGrid ClientDataSource binding: after filtering so no records are present and removing the filter there is no pager

Problem

On Radgrid with client side binding - if you filter the grid and find no records, then remove the filter to have data back, the paging is not recreated.

Repro steps:

1. go to the RadClientDataSource binding demo: Binding to Telerik ClientDataSource
2. filter a column so there is no data in the grid
3. remove the filter

Actual: the pager is gone

Expected: the pager is there

Visualization of the problem:

Solution

Add a handler to the OnCommand client-side event of the grid and show the pager:

<script>
    function OnCommandHandler(sender, args) {
        if (args.get_commandName() == "Filter") {
            $telerik.$(sender.get_element()).find(".rgPager").show();
        }
    }
</script>
<telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" runat="server">
    <ClientSettings>
        <ClientEvents OnCommand="OnCommandHandler" />
    </ClientSettings>
</telerik:RadGrid>
