----------------------------------------------------------- From: _Neeraj_ Message 2 in Discussion Probably, you can do one thing : 1. Put the data for the second dropwonlist in the XML format in the HTML server side control. 2. Attach the javascript function to the first combo on its onchange event, and pass it necessary data ( say id) on which you want to disaplay the data in the second combo.. 3. In the javascript function, instantiate the XML DOM object and reduce the XML using XPath query using passed id and then loop through the shortened xml add the data in the second dropdownlist. Note that at any point of time do not tamper the original xml string of your HTML server control. Because that will be used for each and every change.

I need to populate the values of the second dropdownlist on the basis of the item selected for the first one. Values for both the dropdownlists comes from the database. Problem My page should NOT refresh on the selection of the value in the first dropdownlist but than also it should fetch the values from the database for the second dropdownlist. Since the data is huge I can't put it in viewstate or javascript. Somebody suggested that I can use XMLHTTP to achieve the same. Do any of you guys have done something similar or some code is available ... please respond ASAP .... Best Regards, Praveen View other groups in this category.
