A better refresh button for asp.net pages

Peter has modified his Refresh user control and now page will only redirect to itself that will save one server trip:
A better refresh button for asp.net pages

But this modified control will again not exact solve problem. Redirecting page will not behave like refresh button, as after redirecting to the same page you will going to get fresh instance of page which mean you will loose all values in ViewState, Hidden Field etc. which has been modified with some back post event.

To put my point, place a simple button in the page, and on its click event, add some value in ViewState:
private void Button1_Click(object sender, System.EventArgs e)
{
ViewState["Value"] = "100";
Label1.Text = (string) ViewState["Value"];
}

with that display value of this ViewState key in page load.
private void Page_Load(object sender, System.EventArgs e)
{
Label1.Text = (string) ViewState["Value"];
}

Now if user clicks on RefreshLink control, the value displayed from ViewState will be blank and NOT 100. So it’s basically not simulating the Refresh button exactly.

I still suggest that if you submit the form, its work like Refresh button.

HyperLink1.Attributes.Add("onclick", "document.Form1.submit();");

If user clicks on HyperLink1, page will display same ViewState value which has been modified before. So its actually behaving more like Refresh button.

Here is my suggested RefreshLink control:
[ToolboxData("<{0}:MyRefreshLink runat=server></{0}:MyRefreshLink>")]
public class MyRefreshLink : HyperLink
{
protected override void OnLoad(EventArgs e)
{
base.Attributes.Add("onclick", "document.Form1.submit();");
base.OnLoad(e);
}

public new string NavigateUrl
{
get
{
return base.NavigateUrl;
}
}
}
