[CLOSED] How to use FindControl() on the Panel?

[vadym.f]

Hi,

What's the correct way to get a server handle on the control contained on a TabPanel? The following code doesn't work:

                Ext.Net.Panel activeTab = X.GetCmp<Ext.Net.Panel>("Tab1");
                GridPanel gridPanel= activeTab.FindControl("GridPanel1") as GridPanel; // Returns null

Thanks,

Vadym

Hi,

X.GetCmp destination is the following:

1. It creates a proxy class to generate JavaScript by calling its methods.
2. You can get an access to values from Post collection. For example, if you will create a TextField on client with "TextField1" id, you can access its text this way:

X.GetCmp<TextField>("TextField1").Text

That proxy class is not a real control and it doesn't know anything about a client side "twin" apart from automatically posted values (like TextField text).

So, the "activeTab" has no any child control and the FindControl can't find anything.

Please note if you create a control/widget on client, a server does know nothing about it.

Does it mean that I can't use the FindControl method on any control created on the client? Is there any alternative to that?

Thanks,

Yes, correct. A server does know nothing about widgets created on client.

Well, I can't see any alternative. A single way is getting a required data from client via, for example, DirectEvent ExtraParams.

Thanks for the clarification Daniil! You can mark this question as resolved.
