Hi,
I'm using some cascading combo boxes and normally they work just fine using the standard mechanism of using onclientselectedindexchanging and onitemsrequested. On a couple of pages however I am finding that whilst they again work fine normally if I change a parent value - causing the children to reset to their initial unset states - then on postback the children have their SelectedValues set as empty. The parent combo shows the selectedvalue as the new value. Also the children all show the Text as the newly selected item.
Also if I do some client js before the post back I can see the value is set correctly (using get_value() on the combo box).
I've stripped the code right down to the bare minimum and it just doesn't make any sense why one page works fine but another one doesn't. Any pointers as to why this might be happening?
Regards,
Jon
