Hi,

According to your code, you set AutoPostBack property to false, so if you only operate RadCombobox control, it will not do postback, so you need to add a postback in OnClientSelectedIndexChanged event. Please refer to change you code as below:

function Testing(){

alert('hi')
_dopostback('RadComboBox1',''); 

}

There is a similar thread, please refer to the link below:

Hope it's useful for you.
