I am new to telerik control and having problem with refresh/auto post back. Previous coder has added telerik multi select drop down (with check boxes) and ajax panel. it's working fine when you select this first time.
when drop down is closed and you try to select another value, it lets you select it. you can see new value is selected in drop down text box. soon as you close drop down it changes text box value to previous values. you open third time and you can see selected values that you have choosen second time but it does not update textbox (dropdown box).
see image to get more information.
