Therefore, I use javascirpt as client side event. use DOM document.getelementbyid('<%=wc1.clientID%>') only return 'null' to me.
How can I get the client selected value in javascirpt?
or I should not use document.getelementbyid() ?
there's an Infragistics JavaScript function for that, igcmb_getComboById('<%=wc1.clientID%>') [hope i got it right, cannot confirm it right now]
