Problem with User Control Postback

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.

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

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.

It doesn't work. Please let me know the fix asap.

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.
