I have a fully programmatically implemented Radgrid, with filters enabled. When you implement a Filter Template Class (to make a custom filter), you have to implement the function InstantiateIn, which has the container as a parameter. In this function you add the components of your Filter Template to this container, but I want to add controls to the container from outside this function. Is it possible to find this container form the Page_Load function? I've serached everything, and I have seen that you can get it at ItemCreated or ItemDataBound, I don't exactly remember. But this is not what I want, I want to get it from Page_Load. How can I do that?
