Response.Redirect History -1?

I am handling a FormView's Cancel button as follows in the code.

What I would rather do is simply tell it to go back just one page in the browser's history.
Or perhaps if this is not available, could I pass it the ID of the record I am currently working with in the formView?

Any thoughts? Thanks!

Protected Sub fvContent_ItemCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewCommandEventArgs) Handles fvContent.ItemCommand
        If e.CommandName = "Cancel" Then
            Response.Redirect("Pages.aspx")
        End If
    End Sub

You can write code to render cleint side javascript:

window.history.go(-1);

Yeah - I was kind of hoping for something like that - but I don't know how to write/call JS in ASP.net - very much a newbie... any chance you could show me?

Well depends what you want exactly but something like this works:

<asp:Button ID="Cancel" Text="Cancel" runat="server" OnClientClick="alert('Hello');" />

But for your case you would of course have:

<asp:Button ID="Cancel" Text="Cancel" runat="server" OnClientClick="window.history.go(-1); return false;" />

The return false cancels the submit otherwise the page would do a post.

Is this enough for what you need?

Just about - but the code I am executing is:

    Protected Sub fvPage_ItemCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewCommandEventArgs) Handles fvPage.ItemCommand
        If e.CommandName = "Cancel" Then
            Response.Redirect("Pages.aspx")
        End If
    End Sub

Open in new window
