Question

I have : select id=”select1″ runat=”server”> option>choose something /option> /select>

and I have this javascript function

var op = document.getElementById("select1");

for (i = 0; i < array.length - 1; i++) {
    op.options[i] = new Option(arr[i]);  
}

now after this function, the select has more <option>.

Now When pressing on asp:button, I want to be able to read(on server side) the new selected value.

unfortunately when the server process the page ,all the selcet1 values that was given by the javascript function are gone and the server always see the orignal value of the select1 (“choose something”).

so, I can I read, on server side, the new options of the select1, that was generte by the javascript ?

Thanks for any help

You can loop the values by finding it using Request.Form, like

foreach(string key in Request.Form) {
    Response.Write(key + ": " + Request.Form[key] + "<br />");
}

You might also just find it by using Request.Form["select1"];
