[CLOSED] Still dont understand referencing Controls in Javascript: Select Handler and Button

[wagger]

Hey,
I am still not getting it with the referencing of Controls in Handlers and Javascript.

I have a ComboBox (inside a UserControl) and it has a Select Handler. I want that Select Handler to show a hidden button:

                        <Listeners>
                            <Select Handler="#{Field_Address_Icon}.setVisible(true)"/>
                        </Listeners>

I have tried without the # too:

                        <Listeners>
                            <Select Handler="Field_Address_Icon.setVisible(true)"/>
                        </Listeners>

The Button I am trying to access is placed inside thte same ColumnLayout:

<ext:LayoutColumn ColumnWidth="0.04">
      <ext:Button ID="Field_Address_Icon" Icon="BulletTick" runat="server" StandOut="true" Visible="false"></ext:Button>
</ext:LayoutColumn>

I have also tried with different IDMode, "Explicit", "ExplicitClientID", "Ignore" to no avail. I just keep getting

Uncaught ReferenceError: Field_Address_Icon is not defined

Hi,

#{Field_Address_Icon} should work if the ComboBox and the Button are placed in the same page.

Do you use any IFrames?

Hey,
the Controls are all in the same Page, which happens to be an iFrame in another page but as far as there Controls go, they are all in the same Page (userControl).

Hi,

You set Visible=false for Field_Address_Icon. In this case, widget will not be rendered at all (will not be presented on client side)
Please use Hidden instead Visible

Ah, that did the trick indeed. Thx =)
