Ext.Net, UpdatePanel and Panel Javascript Error

Hello,

I have inside an updatepanel a panel with a button and textfield. When I clicked the button, after the Postback, the following javascript error appears in the browser

Code:

Error: Syntaxerror Ext.onReady(function(){if (Ext.query("div[id=Panel1_Container].AsyncRender").length>0){Ext.net.ResourceMgr.destroyCmp("Panel1");Ext.create("Ext.panel.Panel",{"id":"Panel1","renderTo":"Panel1_Container","items":[<#:anchor id="txtTime_ClientInit" />,<#:anchor id="cmdAdd_ClientInit" />] ....

I use the following component-versions

Code:

Ext.Net 2.4.0.30143 .Net Framework 4.5.1 Windows 7 x64

Default.aspx

Code:

<asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <ext:resourcemanager id="SCM" runat="server" enableviewstate="true" disableviewstate="false" initscriptmode="Inline" clientidmode="Predictable" namespace="" quicktips="true" renderscripts="Embedded"></ext:resourcemanager> <div style="position: relative;"> <ext:TextField ID="txtTimeOutside" runat="server" FieldLabel="Time outside"></ext:TextField> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false" EnableViewState="true"> <contenttemplate> <ext:Panel ID="Panel1" runat="server" > <Items> <ext:TextField ID="txtTime" runat="server" FieldLabel="Time"></ext:TextField> <ext:Button ID="cmdAdd" runat="server" Icon="Add" Text="Submit" AutoPostBack="true"></ext:Button> </Items> </ext:Panel> </contenttemplate> </asp:UpdatePanel> </div>

Default.vb

Code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If IsPostBack = False Then txtTime.Text = Now txtTimeOutside.Text = Now End If End Sub Private Sub cmdAdd_Click(sender As Object, e As EventArgs) Handles cmdAdd.Click txtTime.Text = Now UpdatePanel1.Update() ' Error SCM.AddUpdatePanelToRefresh(UpdatePanel1) ' Script is correct ' Panel1.toScript() End Sub

When I checked the script in the button-event with the following code line

Code:

Panel1.toScript()

I got a correct script.

Can everyone help me.

Hi,

Is there any particular reason why you need to use an UpdatePanel? We highly recommend you remove from your project. There is *always* a better option to the UpdatePanel.

Hello,

thank you for your answer. In the current project I want to change from the Ext version 1.5 to the latest version, without rewrite the whole program. I also want to keep the effort for testing low.

The UpdatePanel is not the answer to your requirements. I highly recommend you remove as many instances of the UpdatePanel from your Project as you can. There are much better options that require less code and are more robust solutions.

Mixing of these (very) old school ASP.NET techniques with an Ext.NET application (or any modern application) is going to yield unexpected results and make testing difficult. Your requirements for an easy upgrade are undermined by the decision to use UpdatePanel.

Our official policy on the UpdatePanel is the following:

UpdatePanel: It works, except when it doesn't.

If the UpdatePanel works in your Ext.NET application, then great. If it doesn't, then there's probably not much support we can provide.

We're also thinking about completely removing all support for UpdatePanel from Ext.NET 3. There's just no need to have that kind of bloat inside the framework, and we do not want to encourage developers to use the UpdatePanel, so it's probably best if we remove support.

Hello,

Thanks for the information. I'll think now, what are the options for the conversion.

Thanks for the help, please mark this thread as closed.
