Question

I have an update panel that has a button with a handler:

protected void btn_Click(object sender, EventArgs e)
{
    ScriptManager.RegisterStartupScript(Updater, this.GetType(), "Hash Update", "UpdateServerData('" +
            avalue + "');", true);
}

and a javascript function:

function UpdateServerData(val) {
    parent.location.hash = val;
}

The first time I click the button after the page loads, the value is written to the location. hash, but is cleared out. The next click functions the way it should. I can’t figure it out. Any help appreciated.

Answer 1

Go it. Apparently there is a bug in .Net 3.5 with partial postbacks that removes the Hash. the answer was here http://magnuskragelund.dk/url-with-hash-mark-changing-after-partial-postback/

thanks for your help though.
