(Hard one,any expert out threre ? ) Create object from string ? add webcontrols dynamically on page.

[jesper_lofgren]

Hi there,

I have some webcontrols that i want to add dynamically on a page. I
have stored the path / namespace in database (ex
MyNameSpace.WebControls.Control1) to the class/webcontrol.


Lets say i have a column in database that looks like this.


PageID (int) Webcontrol (varchar)
1 MyNameSpace.WebControls.Control1
1 MyNameSpace.WebControls.Control2


Then i want to add the controls dynamically on the page, anyone know
how to do this ?
I guess i have to create a instance of the webcontrol and the add it
with Controls.add() . But how do i create the instance and add it
dynamically from a string?


Hope anyone can help me with this, some expert out there ??


Thanks
Jesper

Assuming the types are declared in the same assembly, then you can use this
version of Activator :

Control newControl = (Control) Activator.CreateInstance(null,
"MyNameSpace.WebControls.Control1");

If the type is in another assembly, then the first parameter should be the
assembly name.
