Cascade dropdownlist in edit mode of grid sends old value on the cascaded list

[Sameh Awad]

Hi,

I have a grid with 2 cascade dropdownlist. When I am in the edit mode of the grid using a popup, and i change the value of the parent dropdownlist, the second dropdownlist is repopulated correctly. But if the user doesn't choose anything from the second dropdownlist and just submits. The old value of the second dropdownlist is sent to the controller in the bound model. Although this seems correct by design since the user didn't actually change the value of the second dropdownlist but for data integration this is incorrect.

What I want to be able to do is change the value of the second dropdownlist when the first one changes into a default value of zero for example or null, so that it would trigger the validation error of the dropdownlist.

Best regards,
Sameh

Hello Sameh,

I could suggest you to use the change event of the first DropDownList to set the value of the child DropDownLIst to a default one.
