I am trying to convert this line of ASP code into my aspx.cs page so that when the user clicks on the RETRY button on the web page it goes back to the last page they were on:

strHTTP = trim(Request.ServerVariables("HTTP_REFERER"))

<input Type="Button" Value="Retry" Name="Retry" onClick="window.location='<%=strHTTP%>'">

I tried the following but got a compilation error stating no definition for history:

<asp:button id="retryButton" Text="Retry" Runat="server" OnClick="history.back()">

How do I do the same thing in my .aspx page?

Any help or direction would be appreciated.

Regards.

<asp:button id="retryButton" Text="Retry" Runat="server" OnClick="javascript:history.back()">

Though what is happening is it is mapping to the server event instead of the client. Try adding it through code-behind:

retryButton.Attributes.Add("onclick", "javascript:history.back");

Brian,

Thanks for the help. I did add this second example: retryButton.Attributes.Add("onclick", "javascript:history.back");
to the CODE-BEHIND in the following event:

private void retryButton_Click(object sender, System.EventArgs e)
        {
            retryButton.Attributes.Add("onclick", "javascript:history.back()");
        }

However, what seems to happening is that the current ERROR PAGE that I am originally coming to when I get an error is not retrying the last page but this same ERROR PAGE that I got to.

Any suggestions would be appreciated. Thanks, again!!

You might have to use Response.Redirect

If you are going to use only history.back() or history.go(-1) then you could create a Html button instead of a server control. On the onClick of it call this js code.
