Hidden value assigned in js lost after postback

Question

Here\'s my problem. I have a hidden field whose value I change through a javascript method. The problem is after postback the value is lost.

How can I persist the va

Answer 1

You don't need to have the hidden input run at server. You can do:

Then when you post back you can access it like that:

protected void BtnGuardar_Click(object sender, EventArgs e)
{
    String test = Request.Form["HiddenInput"];
}
