You want to use the client side onblur event for lost focus. Some ajax with jquery would probably work nice for what you are doing.

send me coding how to create client side lost focus

[ZiadElmalki]

Send you code?

<input onblur="alert(' lost focus');" />

Something like that.

Here is the jquery on blur api.

You can also use the OnSelectedIndex Changed change on the combobox making sure to set autopostback to true but you should try to do use ajax and make async on client.
