ASP.NET Button to redirect to another page

<button type ="button" onclick="location.href='@Url.Action("viewname","Controllername")'"> Button name</button>

for e.g ,

<button type="button" onclick="location.href='@Url.Action("register","Home")'">Register</button>

You can use PostBackUrl="~/Confirm.aspx"

For example:

In your .aspx file

<asp:Button ID="btnConfirm" runat="server" Text="Confirm" PostBackUrl="~/Confirm.aspx" />

or in your .cs file

btnConfirm.PostBackUrl="~/Confirm.aspx"

u can use this:

protected void btnConfirm_Click(object sender, EventArgs e)
{
  Response.Redirect("Confirm.aspx");
}

You can either do a Response.Redirect("YourPage.aspx"); or a Server.Transfer("YourPage.aspx"); on your button click event. So it's gonna be like the following:

protected void btnConfirm_Click(object sender, EventArgs e)
{
    Response.Redirect("YourPage.aspx");
    //or
    Server.Transfer("YourPage.aspx");
}
