Using asp:UpdatePanel and asp:Repeater in Kentico 8.1

Added missing sample code:

<asp:Repeater ID="rptRepeater" runat="server" OnItemDataBound="rptRepeater_ItemDataBound"> 
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <fieldset>
                Show Data Here
            </fieldset>
        </ContentTemplate>
    </asp:UpdatePanel>
</asp:Repeater>

Put the update panel around the repeater and pager. If you use the portal mode, you can just check "Add update panel" in the web part or web part zone properties.

You can use below code instead: <asp:UpdatePanel ID="UpdatePanel1" runat="server"> </asp:UpdatePanel>

Also you can use Kentico in built repeaters ( cms:BasicRepeater, cms:QueryRepeater, cms:Repeater) which gives you more options to work with Kentico items

You can use below code instead: <asp:UpdatePanel ID="UpdatePanel1" runat="server"> </asp:UpdatePanel>

Also you can use Kentico in built repeaters ( cms:BasicRepeater, cms:QueryRepeater, cms:Repeater) which gives you more options to work with Kentico items

You can use below code instead:

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
        <asp:Repeater ID="rptRepeater" runat="server" OnItemDataBound="rptRepeater_ItemDataBound"> 
            <ItemTemplate>
                <fieldset>
                    Show Data Here
                </fieldset>
            </ItemTemplate>
        </asp:Repeater>
    </ContentTemplate>
</asp:UpdatePanel>

Thanks all!

@REZA ZAREIAN FARD Yesterday, I was use your way, but It's not worked. However, today I just re-tried and the application can run without error. But, the page still refresh. Here is updated code:

.ascx file:

<asp:UpdatePanel ID="upReportsList" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <asp:Repeater ID="rptReportsList" runat="server">
            <ItemTemplate>

                <tr>
                    <td class="auto-style2">&nbsp;</td>
                    <td class="auto-style3">
                        <a href='/Create-Report/Detail-Report.aspx?ReportId=<%# Eval("ItemID") %>'>
                            <%# Eval("ItemID") %>
                        </a>
                    </td>
                    <td>
                        <a href='/Create-Report/Detail-Report.aspx?ReportId=<%# Eval("ItemID") %>'>
                            <%# Eval("ItemReportName") %>
                        </a>
                    </td>
                </tr>
            </ItemTemplate>
        </asp:Repeater>
        <asp:Label ID="lblPageCount" runat="server" Style="font-weight: 700"></asp:Label>
        <asp:Button ID="btnPrev" runat="server" Text="Previous" OnClick="btnPrev_Click" />
        <asp:Button ID="btnNext" runat="server" Text="Next" OnClick="btnNext_Click" />
    </ContentTemplate>
</asp:UpdatePanel>

Code behind for buttons action:

protected void btnNext_Click(object sender, EventArgs e)
{
    //send to next page
    Response.Redirect(string.Format("{0}{1}", "~/Reports-List.aspx?Page=", Convert.ToString(_pageNum + 1)));
}
protected void btnPrev_Click(object sender, EventArgs e)
{
    //send to previous page
    Response.Redirect(string.Format("{0}{1}", "~/Reports-List.aspx?Page=", Convert.ToString(_pageNum - 1)));
}

Please let me know where do I need to change?

Your page is refreshing because you are specifically stating Response.Redirect() You are telling the page to navigate away from the current page and go to another page, it doesn't matter if you're adding new parameters or not, your redirecting the page an update panel will do nothing for that.
