Re: Simulate button click to trigger postback

I'm currently setting a flag and calling submit(), which causes a postback.
Now I have the mysterious problem that when my Page_Load fires, and calls
the refresh code, nothing happens, but when I click the Refresh button
straight after that, the page does refresh.

My code follows (the '$' function is a dirty shorthand for
GetElementsByTagName).  In both cases InitGrid is called, but the page only
refreshes when btnRefresh is clicked.


function refreshMainForm() {
    var myForm = $('m').contentDocument.forms[0];
    debugger;
    if (myForm.isRefresh)
    {
        myForm.isRefresh.value = "y";
        myForm.submit();
    }
}

protected void Page_Load(object sender, EventArgs e)
{
    if ((!IsPostBack) || (isRefresh.Value == "y"))
    {
        isRefresh.Value = "";
        lblFormName.Text = MyController.FormName;
        InitGrid();
    }
}

protected void btnRefresh_Click(object sender, ImageClickEventArgs e)
{
    InitGrid();
}
