Display text w/out page reloading
Hi xperts
I have a dropdownlist that has four values. I have called a function in the 'OnSelectedIndexChanged' event and some text gets displayed in a label control. My problem is, to make this happen, I need to make the AutoPostBack="true" for the dropdownlist control. Every time I select one value from the list, the page gets posted. I tried to use JavaScript to set focus on the control. That worked, but the control is somewhere middle of the page and after postback, the page gets diplayed from the top. This is not required by my client. He wants that he will be able to see the dropdownlist after selecting any value from the list.
Is there anyway I can do this stuff w/out reloading the page? I need to keep the dropdownlist control as server-side control. I am using VB as the scripting language. No C# solution is reqrd.
Thanx in anticipation.

You have to use JavaScript; however, you may be able to display the page from the middle as desired using JavaScript. Not quite sure how to do it myself.

If you have set AutoPostBack="true" it will always reload the page.

To reach that u have to use Clint-Side programing & in order to get Server-Control's value by JavaScript use:
Code:
FORM_NAME.elements['DropDownList_NAME'].selectedIndex
HTH.

Thx. But the prblem w/ this solution is I cannot declare it as a server-side control. I am saving the form data into a database, so I am calling a subroutine in the click event of the submit button, and save the data in an acces file. So, u see, I have to declare the control w/ runat="server" tag, and the only event available is the OnSelectedIndexChanged and that only works w/ AutoPostBack = "true" option. So, why people say ASP.Net is powerful than Classical ASP? Can't I do this simple thing?
