Whenever i have to load values in a grid in a direcmethod or directevent, if i place an upload field in the page, loading gets very sluggish. If i comment or remove the upload field loading gets normal again.

Anyone knows a fix for that?

Follows example. Just type something in the textfield and leave the field. Grid will be loaded on the blur event very slowly. Then, comment the upload field (id fup) and do the same. Grid will load almost instantly.
