I wanted to build a picker control that would work upon a ECT like the out of the box picker but at the same time would also be able to show the picker dialogue based on some filtering criteria programmatically fed into it and the user will not be able to use the filters in the dialogue pop up.
till now the only blog that talks about building a custom picker is : http://sharepointsolutions.com/sharepoint-help/blog/index.php/2009/10/create-a-custom-picker-in-sharepoint-2010/
Could someone tell me how to achieve this? Hopefully without having to build a whole custom control for myself.
Thanks, --OM
