Get FileExpolorer pagerindex

[Fit2Page]

Hi,

Any idea why the following clientscript always returns 0?

var oExplorer = $find("<%= RadFileExplorer1.ClientID %>");
    alert(oExplorer.get_listView().get_currentPageIndex());

Thanks,

Marc

Hello Marc,

The ListView is the control, which is listing the files when FileExplorer's ExplorerMode is set to Thumbnais. I assume that you are using FileExplorer in the default grid mode, which means that you can access the current page index in a similar way:

<telerik:RadFileExplorer runat="server" ID="RadFileExplorer1" AllowPaging="true" PageSize="5" ExplorerMode="Default">
    <Configuration ViewPaths="~/" />
</telerik:RadFileExplorer>
<asp:Button ID="Button1" runat="server" Text="Current page" OnClientClick="ShowPage(); return false;" />
<script type="text/javascript">
    function ShowPage() {
        var oExplorer = $find("<%= RadFileExplorer1.ClientID %>");
        alert(oExplorer.get_grid().get_masterTableView().get_currentPageIndex());
    }
</script>

I hope this helps.

Hi Veselina,

That is just the point. I use ListView mode but I cannot read the PagerSetting.
Can you reproduce this?

Hi Marc,

Thank you for the clarification - indeed I was able to reproduce the described issue in Thumbnails mode of FileExplorer and I have logged it int our bug tracking system. You can see the progress of the bug here: feedback. I have also updated your Telerik Points accordingly.

For he time being, you can use the following workaround in order to access the current page index:

function ShowPage() {
    var oExplorer = $find("<%= RadFileExplorer1.ClientID %>");
    var slider = $find(oExplorer.get_id() + "_FileListPageControlSlider");
    var pageIndex = slider.get_value();
    alert(pageIndex);
}

I hope this helps.

Hi Veselina,

I try to explain what my exact problem is. I discovered that the pager in the RadFileExplorer remembers it's own setting when I have the FileExplorer set on GridView. When I switch to Listview the Pager setting is not kept. I use a FileExplorer in which I added an ImageEditor to the Context menu. So let's say when I open the imageEditor for a file on page 2 and I cancel it the pager always returns to page1. In GridView it neatly stays on page 2.

I can send code if that would you help to reproduce the problem.

Hello Marc,

The pager in the GridView mode of FileExplorer is built-in the Grid control, while the one in the ListView is additionally added Slider control, so it does not provide all the functionality which come with the Grid.

What I could suggest you is to save the current page in a hidden field (you can do it on your custom context menu item's Client-Click handler) and to set it as a value to the Slider when the ImageEditor is closed. In order to access the current value of the Slider, you can use the method provided in my previous reply:

var oExplorer = $find("<%= RadFileExplorer1.ClientID %>");
var slider = $find(oExplorer.get_id() + "_FileListPageControlSlider");
var pageIndex = slider.get_value();

and respectively to set the desired value in a similar manner:

slider.set_value(2); //sets the page index

I hope this approach will be suitable for your scenario.
