I am following the Managing Browser History asp.net example article but I have a problem with updating the LabelHistoryData label after clicking the browser back button. I placed a breakpoint at \[code\]LabelHistoryData.Text = Server.HtmlEncode(e.State["s"]);\[/code\]but somehow after clicking btnGetInboxList or btnGetSentboxList follow by the browser back button, the LabelHistoryData.Text value is always null. Below is a portion of my code. Someone please kindly advice. Thanks.\[code\] <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="True" OnNavigate="OnNavigateHistory" EnableHistory="true" EnableSecureHistoryState="false" /> <asp:UpdatePanel ID="uiupInboxMainGrid" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:Label runat="server" ID="LabelHistoryData" /> <asp:Button ID="btnGetMessageContent" runat="server" Text="MsgContent" OnClick="GetMessageContent_Click" /> <asp:Button ID="btnGetInboxList" runat="server" Text="Inbox" OnClick="GetInboxList_Click"/> <asp:Button ID="btnGetSentboxList" runat="server" Text="OutBox" OnClick="GetSentBoxList_Click" /> </ContentTemplate> </asp:UpdatePanel> public void OnNavigateHistory(object sender, HistoryEventArgs e) { LabelHistoryData.Text = Server.HtmlEncode(e.State["s"]); } protected void GetInboxList_Click(object sender, EventArgs e) { LabelHistoryData.Text = ((Button)sender).Text; ScriptManager.GetCurrent(this).AddHistoryPoint("s", LabelHistoryData.Text, "Entry: " + LabelHistoryData.Text); } protected void GetSentBoxList_Click(object sender, EventArgs e) { LabelHistoryData.Text = ((Button)sender).Text; ScriptManager.GetCurrent(this).AddHistoryPoint("s", LabelHistoryData.Text, "Entry: " + LabelHistoryData.Text); } protected void GetMessageContent_Click(object sender, EventArgs e) { LabelHistoryData.Text = ((Button)sender).Text; ScriptManager.GetCurrent(this).AddHistoryPoint("s", LabelHistoryData.Text, "Entry: " + LabelHistoryData.Text); }\[/code\]
