Filter dropdown in edit mode based on previous selected dropdown(s)

[Johan]

Hi

I'm using the approach found here (Editing Custom Editor) to bind some of my fields during edit mode to dropdown menus.

Everything works great but I need to know if it is possible to filter dropdowns during edit mode based on a previous selected value, which also happens to be a dropdown.

To help explain myself better, here is how the structure work:

[dropdown 1]                                     [dropdown 2]                                                              [dropdown 3]
select * where parentId = null      select * where parentId = id of dropdown 1     select * where parentId = id of dropdown

As you can see above, I will need to find a way to query the server on each change of the dropdown item to filter out the data I need to bind for the next dropdown.

I will appreciate it if anybody can point me in the right direction or perhaps to some relevant samples.

Thanks

Hi Ryno,

 
Please note that we already provide such example of using cascading DropDownLists in Grid InLine and PopUp edit modes in our CodeLibrary:
