RadListView issue

[Kamal Mostofi]

Hi,

I followed the example from your demo page. I am trying to display images as sushi page. I like to do the following:

1. Display 10 images
2. Select an image
3. navigate through each page on listview

The problem I have is that each time I navigate through the page, my asp page reload itself and doesn't use ajax method.
Could you please tell me what I am missing here?
Please see the code below
'Format Code Block'(<asp:ObjectDataSource ID="dslogo" runat="server"

 

 

 

 

 

OldValuesParameterFormatString="original_{0}"

 

 

 

 

 

 

 

SelectMethod="ListImages"

 

 

 

 

 

 

 

TypeName="logosBLL.logo" >

 

 

 

 

 

 

 

 

</asp:ObjectDataSource>

 

 

 

 

 

 

 

 

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<telerik:AjaxSetting AjaxControlID="SushiPanel">

 

 

 

 

 

 

 

 

<UpdatedControls>

 

 

 

 

 

 

 

 

<telerik:AjaxUpdatedControl ControlID="SushiPanel" LoadingPanelID="RadAjaxLoadingPanel1" />

ItemPlaceholderID="PlaceHolder1" AllowPaging="true">

 

 

 

 

 

 

 

 

<LayoutTemplate>

 

 

 

 

 

 

 

 

<div class="sushibar">

 

 

 

 

 

 

 

 

<asp:Panel ID="SushiPanel" runat="server">

<telerik:RadDataPager ID="RadDataPager1" runat="server" PageSize="10" Skin="Black">

 

 

 

 

 

 

 

 

<Fields>

 

 

 

 

 

 

 

 

<telerik:RadDataPagerButtonField />

 

 

 

 

 

 

 

 

</Fields>

 

 

 

 

 

 

 

 

</telerik:RadDataPager>

 

 

 

 

 

 

 

 

</asp:Panel>

 

 

 

 

 

 

 

 

</div>

 

 

 

 

 

 

 

 

</LayoutTemplate>

 

 

 

 

 

 

 

 

<ItemTemplate>

 

 

 

 

 

 

 

 

<div class="category">

 

 

 

 

 

 

 

 

<asp:Image runat="server" ID="imglogo2" Height="70px" Width="70px" ImageUrl='<%# Eval("logopath") %>' />

 

 

 

 

 

 

 

 

</div>

 

 

 

 

 

 

 

 

</ItemTemplate>

 

 

 

 

 

 

 

 

<SelectedItemTemplate>

 

 

 

 

 

 

 

 

<div class="selected">

 

 

 

 

 

 

 

 

<asp:Image runat="server" ID="imglogo2" Height="70px" Width="70px" ImageUrl='<%# Eval("logopath") %>' />

 

 

 

 

 

 

 

 

</div>

 

 

 

 

 

 

 

 

</SelectedItemTemplate>

 

 

 

 

 

 

 

 

</telerik:RadListView>

And also I get the following warning in my project:
Warning 6 Reference to type 'System.Web.UI.WebControls.IPageableItemContainer' claims it is defined in 'd:\Visual Studio 2010\Projects\wave10\wave10\bin\System.Web.Extensions.dll', but it could not be found c:\Program Files (x86)\Telerik\RadControls for ASP.NET AJAX Q1 2010\Bin35\Telerik.Web.UI.dll wave3

Many thanks in advance

Hi Kamal,

Thanks for the sample code. I can see it's almost identical to the RadListView Sushi demo you are referring to. I cannot spot any misconfiguration. Your RadControls for ASP.NET AJAX installation package should also come with a local copy of the Quick Start demo application that you can see live. You can open the application and test it locally. Your listview and AJAX manager definitions seem identical.

If the problem persists, consider opening a regular support ticket where you can send us a sample project we can run locally. This will help us in identifying the source of this issue and will enable to assist you further.

Hi,
The problem was related to System.Web.Extension version. The previous version was targeting .net 2, but when I upgraded my project to VS 2010 and using the latest version of Telerik tools, I missed to update System.Web.Extension to .net 3.5.

When I made the chanegs, it works fine without any postback or flicking page.

Thanks,
Kamal
