Client side OnCommand page number issue

[Joe]

Hi,

I recently attached a javascript event handler the client event OnCommand. I noticed that when I select a page using the numeric pager, the command argument for the event is the page number. For instance, I select page 1, the command name is 'Page' and the command argument is 1. When I select page 1 using the master table view set_currentPageIndex, I get the command name 'Page', but the command argument is 0, the index value I passed to the function. This has caused me some difficulty as I don't necessarily have a way of determining how the event was originally triggered.

Obviously it would be preferable if it used either the page number or the index, but not both.

I am currently on 2010 Q2.

Thanks,
Joe

Hello Joe,

You should use the MasterTableView's page function instead of set_currentPageIndex property.
For example, if you use the code bellow you will get the same alert when clicking on the second numeric pager button and the external one.

<script type="text/javascript">
  function CommandHandler(sender, args) {
    alert("Argument: " + args.get_commandArgument());
  }
  function ChangePageIndex(pageIndex) {
    var grid = $find("<%=RadGrid1.ClientID %>");
    var mtv = grid.get_masterTableView();
    mtv.page(pageIndex);
  }
</script>
<div>
  <telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource"
    PageSize="3" AllowPaging="true">
    <ClientSettings>
      <ClientEvents OnCommand="CommandHandler" />
    </ClientSettings>
  </telerik:RadGrid>
  <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="ChangePageIndex(2); return 0;" />
</div>
