Accessing aspx.cs class from javascript

given something like this:

public partial class MyDialog : System.Web.UI.Page
{
    public int ID;
    protected void Page_Load(object sender, EventArgs e)
    {
        ID = Int32.Parse(Request["ID"]);
    }
// etc
}

out of curiosity, is it possible to set ID from a javascript function in an aspx page? i believe that i can read it via '<% ID %>' but can i set it? if so, how? would the same principle hold true in using mutators?

Dynamic Controls inside a gridview

Hi,

I have a gridview that will have a dynamic contorl in edititem template column based on a value from the database and that works fine i am able to populate the gridview with the correct control. Once the gridveiw has the correct control on it whether it be a textbox, datepicker, dropdownlist or checkbox I need to then allow them to save this into the database but that is were the problem is coming up. It is losing the control that was on the grid when it does the postback so then it is erroring out saying a null reference. I have looked every where and I cannot figure this out. How do i save the value in the dynamic control to the database and also how do i create the contorls for that gridview on page_load as ppl have suggested if i do not know if that row need a textbox or dropdown or whatever. Currently i am creating the contorls on the gridview rowdatabound event. Please help!!!!
