Hi all,

I have a hierarchical class named sector that is the parent of city and the city class is the parent of zipCode class.

I have also a class named company that is assigned to a zipCode.

I want in the company management window to first, select the sector and I do not have the possibility to select neither the city neither the zip code, when the sector is selected, we can select a city from the child cities of this sector and then we can select the zip code.

please can you help me, how can I do that? It's urgent.

Thanks a lot.

Hi,

 Thanks a lot Mohsen I'll see it.

Hi,

In this demo project there is no what I want to do. There is the use of DataSourceProperty but what I want is haw to use 4 dropDownLists that each one is dependent on the value of the previous one, and we can select only if the previous dropDownList has a selected value.

regards, Souheïl.

 It's ok I find haw to do that.
