Optimize a C# base form for fast loading

We have a desktop application written in C# with interface from Devexpress WinForms V14. 90% of the forms displayed in our application have a BaseForm that contain a lot of custom controls of the same type (we called those controls UserControlZona). The UserControlZona custom control is a GridView with buttons. In the BaseForm, for each UserControlZona there are events to trigger button clicks, row clicks and focused row change. Currentlly we have about 30 UserControlZona in the BaseForm and we display them selectivelly depending on what we need to accomplish, but every time a form that has the base BaseForm, it loads all UserControlZona that are in the base even thought we need only some. We need to optimize this behaviour so that when a form having the base BaseForm loads, it loads only the UserControlZonas that are displayed. Another optimization that we need for this BaseForm comes from the fact that we need to refresh displayed UserControlZonas based on FocusedRowChanged and RowClik (even thought the clicked row is already focused) from other UserControlZonas. Even thought it seems simple we had trouble with this because he ended up refreshing the UserControlZonas several times on a single click or on focused row change. We had this same issue on the OnLoad event (same UserControlZona) refreshing multiple times. The code in in C# and we used only controls from DevExpress V14 (you will need to install it in order to run our project). If you feel up to the task, to finish in a reasonable time, please bid. If we are pleased with the results we have other tasks in store :)
