HI:

    I have done Paging on  " Datalist"    in   DotnetNuke.The Paging is working fine in the normal condition....But the Problem is If  i refresh the page  or press Control+F5      I cudn't get the current page. The Event occured before refresh the page is calling ,so that the page is incremented or decremented accordingly.So i have planned to use Ajax "UpdatePanel".After Using Updatepanel while running the page i got exception.Can any one tell  me how to solve this problem.I have attached my code below.

My Code:

 

 
                                           
                                      
                                  <asp:ScriptManager ID="ScriptManager1" runat="server">
                                                </asp:ScriptManager>
                                           
                                           
                                                <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                                                <ContentTemplate>

Although it appears that some of your markup code became "scrambled" in posting to the forum, I do see that you are declaritively adding a ScriptManager control. Since there can be only one ScriptManager control on a page and since other modules or the DNN framework itself may be adding one already to the page markup, I suspect that your error message is similar to: "Multiple controls with the same ID 'ScriptManager' . . . "

Rather than adding the ScriptManager control declaritively, include code such as the following in your module control:

If DotNetNuke.Framework.AJAX.IsInstalled Then
     DotNetNuke.Framework.AJAX.RegisterScriptManager()
End If

Regarding paging, it appears that you are implementing your own paging rather than using the dnn:pagingcontrol. Unless paging information is passed in the query string, refreshing the page or hiting F5 will always take you back to the initial page.

Sorry I forgot to mention that . . . the code can be placed in either the Page_Init or Page_Load handler. It needs to be called on each page request so do NOT place it within a "If Not Page.IsPostback . . . " conditional.
