OnClientSelectedIndexChanged fires twice

[Joseph]

Hi guys,

I am trying to do some logic when a new value is selected from the combobox.

I hooked up a callback function to the OnClientSelectedIndexChanged event. When I select a new element the event fires and when I click anywhere else ( the Combobox will lose focus) the event will fire again.

How can I overcome this?

Hello Joseph,

I tried to reproduce the issue on our side but without success.
Could you please explain in more details your implementation and paste the code here?

Kind regards,

I am facing exactly the same issue this is so frustrating , telerik gives hundreds of features but when you go ahead to implement them  most of them just fail even in the basic scenarious.

I dont know what in this world makes a controls event fire twice but this occurs when the datavaluefield contains duplicate values so in case the last selected value is equal to the current selected value the event fires twice.
 
This is lack of quality testing

Hi Vivek Verma,

Please note that the values of RadComboBox items have to be unique.
