[CLOSED] App is undefined

[maurox]

Hello

in my solution all controls are undefined.

For example:

<Items>
<ext:TextArea ID="TextArea1" runat="server" EmptyText="[Incolla qui il testo]" AutoUpdateData="true"  />
</Items>

ResourceManager (in master page)

<ext:ResourceManager runat="server" ID="resourceManager1" Theme="Neptune" ScriptMode="Debug" ShowWarningOnAjaxFailure="true" >

is always undefined if i try to do this:

App.TextArea1.clear()

i've installed ext.net with NuGet package and i never override namespaces.
i've a masterpage with resource manager and 1 child page...

Whats wrong?

Thanks

Hi @maurox,

When you use a Master Page, controls have the ContentPlaceHolderID appended to them. Thus they become ContentPlaceHolderID_ControlId

Check the sample below:

<asp:Content ID="sampleHeadContent" ContentPlaceHolderID="headContent" runat="server">
</asp:Content>
<asp:Content ID="sampleMainContent" ContentPlaceHolderID="mainContent" runat="server">
    <ext:TabPanel ID="tabPanel" Width="960" runat="server" Height="599" Padding="1">
        <Items>
            <ext:Panel ID="panel" runat="server" Title="Sample" Height="544">
            </ext:Panel>
        </Items>
    </ext:TabPanel>
</asp:Content>

Therefore, the TabPanel and Panel can be referred to as

App.mainContent_tabPanel

and

App.mainContent_panel

Ok, now it works!

Thanks a lot!
