Hi AliYilmaz,

You have to rebind Begen after saveChanges() method as you have done in the page load. No need to write the refresh method. Refer the below code.

HTML

<div>
    <asp:ScriptManager ID="scriptManager1" runat="server">
    </asp:ScriptManager>
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <asp:LinkButton ID="lnkbegen" title="Beğendim" runat="server" OnClick="lnkbegen_Click"
                Text="Count">
            </asp:LinkButton><br />
            <span class="count-icon"><span class="count" style="right: 5px;" id="spanBegen" runat="server">
                <%--<%#Eval("Begen") %>--%></span> </span>
        </ContentTemplate>
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="lnkbegen" EventName="Click" />
        </Triggers>
    </asp:UpdatePanel>
</div>

Code

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        using (TestEntities tr = new TestEntities())
        {
            spanBegen.InnerText = tr.Yorumlars.ToList().SingleOrDefault(x => x.ID == 1).Begen.ToString();
        }
    }
}

protected void lnkbegen_Click(object sender, EventArgs e)
{
    using (TestEntities tr = new TestEntities())
    {
        Yorumlar y = tr.Yorumlars.SingleOrDefault(x => x.ID == 1);
        y.Begen++;
        y.Begenme++;
        tr.SaveChanges();
        spanBegen.InnerText = y.Begen.ToString();
    }
}
