[CLOSED] DirectMethod and UserControl

[jmcantrell]

When using a DirectMethod within a UserControl, do I have to reference it differently than Ext.net.DirectMethods.MyMethod? The same code works when it's alone on a page, but in the UserControl, I get a javascript error saying that MyMethod is not a property of Ext.net.DirectMethods.

Hi,

The following sample from the Examples Explorer should help solve the problem, see


https://examples1.ext.net/#/Events/D.../UserControls/

I'm trying to call the DirectMethod from a javascript function. Interestingly enough, the following works and I don't see it mentioned in the examples, so it's making me scared. :)

	Ext.net.DirectMethods.<%= Me.ClientID %>.MyMethod(...

Hi,

Yes, correctly, you have to use ClientID of user control (by default)
Also you can use DirectMethodProxyID attribute like in the following example
https://examples1.ext.net/#/Events/D...thods/ID_Mode/

Or use the following shortcut

#{DirectMethods}.MyMethod();

It is mean direct methods of the current scope (for example, if you call it in the user control then will be called MyMethod which is defined in that user control)

Actually, your code is demonstrated in the second "Calling UserControl [DirectMethod] from Parent .aspx Page" sample.


In the sample we use a custom client-side namespace (ie, CompanyX), which replaces the "Ext.net.DirectMethods" bit. And instead of dynamically rendering the UserControl ClientID, we're just hard coding.
