| When using <SELECT> I can use the onchange event to execute some javascript code at the top of my document.However, it appears that when I use <asp:dropdownlist> and the OnSelectedIndexChanged event that I have to post back to the server to execute any code. Is it possible to have javascript code execute on the client side when my asp:dropdownlist is changed or do I have to use a <SELECT> statement to accomplish this? |

| You should be able to add any standard HTML attributes to server-side controls, just be sure that they are rendering to the HTML tag that you expect (i.e., be sure that asp:dropDownList renders as a SELECT, which I am pretty sure it does). Doing this allows you to write client-side script to capture events on the page the same as any other HTML page. Of course, remember that the client-side script cannot interact with server controls, except as rendered in the document object model, since they are in a different context. |

| If you want to fire client side javascript function and disable postback of dropdownlist, set AutoPostBack property to false, then add this code in Page_LoadDropDownList1.Attributes.Add("onchange","jscriptfunctionnamehere();") |
