Problems passing data to view using PRADO

Question

I've been given a website to maintain. The website is using PRADO framework and I had to do some minor changes. There were no problems with the HTML and CSS changes, but now I have to pass some data from a page to a view. I've tried using:

$this->HomeCalendar2->DataSource = $result['data'];
$this->HomeCalendar2->dataBind();

but it says Component property 'Home.HomeCalendar2' is not defined.

Above my code there is the following code:

$this->HomeCalendar->DataSource = $result;
$this->HomeCalendar->dataBind();

and it works perfectly fine and I can't see where is the definition of HomeCalendar. Any help will be appreciated.

P.S: I've never worked with PRADO before.

This question is quite old now, hope you already solved it.

Using DataSource means that there must be in your template (.page or .tpl) a TDataBoundControl component like the folowwing (using TRepeater for example)

<com:TRepeater ID="HomeCalendar">
<!--- [ properties like ItemTemplate here and it contents ] --->
</com:TRepeater>

Subclasses of TDataBoundControl are for component needing to loop results, (sorts of for or foreach somehow). If you juste need to pass a signle result to the view you can use a component like TPanel/TActivePanel, TLiteral, etc. or simply use the expression tag.

Examples :

Expression tag :

Php :

<?php
$this->myvalue = 'Hello World!';

Template :

<h1><%= $this->myvalue %></h1>

Or another solution:

Template :

<com:TLiteral ID="MyLiteral" />

PHP :

<?php
$this->MyLiteral->getControls()->add('<h1>Hello world !</h1>');
