    Hello,

    I created News listing web user control and I have pager at the bottom, which is basically repeater control with link buttons of page number. It works when I put into separate .aspx page, but it doesn't work when I register it with sitefinity.
    I can see first page,  but clicking on any of the other pages [Page number 2,3,4...], shows blank page.

    Please help.

    <asp:MultiView runat="server" ID="multiview1" ActiveViewIndex="0">
       <asp:View ID="viewNewsListing" runat="server">
            <asp:Repeater ID="rptNewsList" runat="server" OnItemDataBound="rptNewsList_ItemDataBound">
                <HeaderTemplate>
                    <ul class="sf_newsList">

    Hello Vaibhavi,

    Could you try enabling the ViewState for the page where you drop your control? It is done when from the Pages grid you select Actions -> Title & Properties -> Enable ViewState

    All the best,

    Thanks you Lubomir !

    I'd knew that the problem was the ViewState of the master page, but i didn't realize how to fix it.

    now everithing is OK

    "AutoPostBack = true" doesn't work for my page. It looks similar problem as its in the user control. I tried enabling viewstate of page from sitesinity admin where the control is placed and also I tried enabling viewstate from code for master page. But no luck.

      <asp:DropDownList ID="ddl1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddl1_SelectedIndexChanged">
                                    <asp:ListItem Text="search engine" Value="0"></asp:ListItem>
                                    <asp:ListItem Text="press advertising" Value="1"></asp:ListItem>
                                    <asp:ListItem Text="word of mouth" Value="2"></asp:ListItem>
                                    <asp:ListItem Text="other web sites" Value="3"></asp:ListItem>
                                </asp:DropDownList>

    mario,
    Did you set EnableViewState="true" in .master page using code? I don't see any way to set it using sitefinity.

    Vaibhavi,

    I didn't need to add anything to my code, just check the "enable page viewstate" in sitefinity

    in the "Pages" section go to: Actions->Title & Properties -> "Enable ViewState" and that's it.

    Hope you solve this.

    Hi Vaibhavi,

    I created a small video that illustrates how I managed to reproduce the effect that you need. Please let me know if this is enough. I also didn't check EnableViewStarte as it is not needed.
