In the above code, I'm trying to set different DataSourceID for SubCtgryRadComboBox depending on MainCatgryRadComboBox Value and display SubCtgryRadComboBox  items (In Update mode, the selectedIndex must be displayed regarding the changes of SubCtgryRadComboBox  .

Please, I need your help,
It is apprecited to send me the modified code.

Bader

Hello Bader,

I am afraid that the code pasted here is not sufficient for us to create a working example for you.

However I can suggest you take a look at the "Using cascading RadComboBoxes into the RadGrid Insert/Edit form" Code Library . 
At this Code Library there is a fully working sample project that you can download and use.

All the best,
Kalina
