        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="SubmitData" />

    </div>
    </form>
</body>
</html>

does anyone know what i am doing wrong?

Solution

It’s just happened to me. It happened when I renamed page and moved aspx file within project folders, but code inside left unrenamed.

Change code inside from:

public partial class foldername_unrenamedname : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }
}

to current

public partial class newfoldername_renamedname : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }
}

And also edit Inherits property in Page tag to:

Inherits="Newfoldername_renamedname"
