I cascade three DropDownLists 'manually'. I don't use the built in cascadeFrom mechanism but I read the dataSource of the child DropDown within the change event of its parent. I do this because I attach a more complicated filter.
This works fine so far, the dataSource is read, data is returned correctly and can be selected in the child DropDown - BUT - I would like the first item of the data to be selected immediately after reading the DataSource. Unfortunately, the child DropDown initially only shows an empty item after loading the new data although, there isn't an empty item defined.
How can I force the child DropDown to show the first item after reading the remote data?
