Hi,

I have used radprompt for entering a filename.below is my javascript:
<script type="text/javascript>
function openPrompt() {
radprompt("please enter the file name", CallBackFn);
}
function CallBackFn(arg) {
alert(arg);
}</script>
The value that i enter is displayed in alert(arg).I don want to display in alert.Instead i want to store the value in a hidden field and use it in server side.how do i do that?please give me the code.

Thanks.

Put a Hidden filed in your ASPX page.

<asp:HiddenField ID="hdnVal" runat="server" />

In your js function assign arg to hidden field.

<script type="text/javascript>

function openPrompt() {

radprompt("please enter the file name", CallBackFn);

}

function CallBackFn(arg) {

alert(arg);

document.getElementById("hdnVal").value = arg;

}</script>

Now you can access your hidden variable value in your code.
