[CLOSED] ext.UserControlLoader in CodeBehind

**supera** · Feb 03, 2012, 3:13 PM

Hi

I try add my own usercontrol in a tabPanel. I´m fail!

I use a UserControlLoader... in my usercontrol, I´m use only ext.net components.

The code to Load my own usercontrol in TabPanel follows:

Occurs two problems:
1 - Add only one tab in tabPanel... I try add many tabs.
2 - The content of usercontrolLoader, (my own Usercontrol) is not show.
3 -

I believe that the problem is the usercontrolloader.addto. Is this a correct mode of add controls in UserControlLoader?
Is there any example for me to follow?

        Dim tabPanelConfig As Ext.Net.Panel.Config = New Ext.Net.Panel.Config
        Dim tabContext As ExplorerWebContext = New ExplorerWebContext
        Dim tabPanel As Ext.Net.Panel
        Dim ucLoader As Ext.Net.UserControlLoader = New Ext.Net.UserControlLoader

        tabContext.Start(Context)

        With tabPanelConfig
            .Title = tabContext.ContextoDescription
            .Closable = True
            .Border = True
            .Padding = 6
        End With

        tabPanel = New Ext.Net.Panel(tabPanelConfig)
        ucLoader.AddTo(tabContext)
        tabPanel.Items.Add(ucLoader)
        tabWebExplorer.Items.Add(tabPanel)
        tabWebExplorer.Render()

Hi,

Please clarify the requirement.

Do you need to add tabs during Page_Load or DirectEvent?

What is the content of tabs - a user control?

Hi Daniil...

I am sorry if I was not clear in my request!

Do you need to add tabs during Page_Load or DirectEvent?

I need add tabs in DirectEvent

What is the content of tabs - a user control?

Yes, I add in tab my own usercontrol.

Please look at the example.

Example Page

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void AddTab(object sender, DirectEventArgs e)
    {
        UserControlLoader ucl = new UserControlLoader();
        ucl.Path = "TestUC.ascx";

        Ext.Net.Panel p = new Ext.Net.Panel("Tab");

        p.Items.Add(ucl);

        this.TabPanel1.Items.Add(p);

        p.Render();
    }
</script>

        <ext:Button runat="server" Text="Add tab" OnDirectClick="AddTab" />
    </form>
</body>
</html>

Example User Control

<%@ Control Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<ext:Panel runat="server" Html="Hello from User Control. I am 1" />

<ext:Panel runat="server" Html="Hello from User Control. I am 2" />

Hi Daniil,

Thanks for your example...

Its is very similar to what I´m doing... But I get different errors in my project...

I have a error in YOUR example... Let´s start with this.
1 - In YOUR example, set the Closable property of tab for True, please.
2 - Run test page.
3 - Add 4 tabs.
4 - Close first or last tab... you will get the following error.

Runtime Error in Microsoft JScript: Type mismatch.

I was unable to reproduce the error following the steps you provided.

Any more changes?

What browser do you test with?

**supera** · Feb 06, 2012, 11:22 AM

Hi Daniil...

You're right about seem to be a browser issue.

After your comment, I ran the test in FireFox 9.0.1, Opera 11.61, Google Chrome 16.0.912.77, and the error did not occur in any of these browsers.

In Internet Explorer version 9.0.8112.16421, update version 9.0.4 (kb2618444), the error occurs.[

I've tested with the same IE9, but still can't reproduce the problem.

I'm testing under Windows 7 Home Premium.

What OS do you test with?

**supera** · Feb 06, 2012, 12:32 PM

Windows 7 Professional with Service Pack 1 64 Bits.
Processor Intel Core i3-2100 CPU 3.10 GHZ
Ram 4 GB

Would you try to access my computer via logmein, teamviewer, vnc or other?

I have the SP1 and 64 bits as well. The single difference is "Proffessional" and "Home Premium". Well, I don't think it might be a reason of the problem, but not 100% sure.

Also I don't think the PC processor and RAM might cause the problem.

Could you double ensure were there no more changes in my example on your side apart from Closable="true"? Did you port it on VB?

I think it's not required on this stage, but I will keep it in mind.
