Asp:LinkButton as an Asp:Panel's Default Button in FireFox

The asp:LinkButton doesn’t work as a panel's DefaultButton in FireFox

Here’s a link explaining the issue:

http://kpumuk.info/asp-net/using-panel-defaultbutton-property-with-linkbutton-control-in-asp-net/

I’ve written a custom control similar to the one in the article (Arke:LinkButton). Which fixes the FireFox issue.

 

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Arke.Web.UI.WebControls
{
[DefaultProperty("Text")]
[ToolboxData("<{0}:LinkButton runat=server></{0}:LinkButton>")]
public class LinkButton : System.Web.UI.WebControls.LinkButton
{
protected override void OnLoad(System.EventArgs e)
{
Page.ClientScript.RegisterStartupScript(GetType(), "addClickFunctionScript", _addClickFunctionScript, true);
string script = String.Format(_addClickScript, ClientID);
Page.ClientScript.RegisterStartupScript(GetType(), "click_" + ClientID, script, true);
base.OnLoad(e);
}
private const string _addClickScript = "addClickFunction('{0}');";
private const string _addClickFunctionScript =
@"  function addClickFunction(id) {{
var b = document.getElementById(id);
if (b && typeof(b.click) == 'undefined') b.click = function() {{
var result = true; if (b.onclick) result = b.onclick();
if (typeof(result) == 'undefined' || result) {{ eval(b.href); }}
}}}};";
    }
}

To use this control...

  1. Add "using Arke.Web.UI.WebControls;" to your code behind.
  2. Register the assembly in the Asp.NET page "<%@ Register Assembly="Arke.Web" Namespace="Arke.Web.UI.WebControls" TagPrefix="Arke" %>"
  3. Add the control (or change your asp:LinkButtons to Arke:LinkButtons) "<Arke:LinkButton ID="ArkeLoginButton" Text="log in" runat="server" CssClass="login_button" />"
