[CLOSED] Dynamic UserControls with DirectMethods
I have a problem in that UserControls are dynamically added to a page via a directevent on page load (listener in resourcemanager) which works and the controls are visible.
on every request the same controls with the same id's are made but not sent to the browser, i.e. not rendered, if X.IsAjaxRequest is true, so the direct methods should hit - and they did in Ext.net v1!
But with version 2 the problem is on the directevent of page load the Ext.net.DirectMethod.request wrappers are not created!! - the controls are sent down but not the wrappers meaning App.direct is undefined, if the user controls are added in the Page_Load the wrappers are made but then the controls are also rendered which we cant do due to the amount of controls - the page needs to load asap which is why we render the controls in a directevent.
Example code:
Default.aspx
App.direct.tstId is undefined
But if you run the javascript:
Ext.net.DirectMethod.request("click", { control: 'tstId' })
it works as you would expect! on the page load direct event Ext generates the following code:
