What is the use Builder extensions from Ext.Net. Where it is useful?

I want to persist the controls that has been created through ajax calls.
Can i achieve it using XRender?

Hi,

It is useful when you need to render controls on the fly (on user's demand). It works during DirectEvent/DirectMethod.

Just to ensure others are aware, there are XRender samples in the Examples Explorer, see

I thought XRender remembers all the controls created by them. But that's wrong. We need to have a good mechanism on server side in order remember the controls created dynamically. Initially i was thinking that XRender meant for that.
I've some more doubts

• What is the Extension function called "ToBuilder()" available for all controls?
• What's the main use of this?
• What is actually this one does?

Yes, it doesn't recreate controls. It just generates a correct JavaScript during DirectEvent/DirectMethod to render/update controls to client.

The Builder class is the special class to create controls via methods. These methods return a Builder instance, it allows to build a chain.

Builders are mainly used in Razor.
