RadMenu Item Click event is not firing

[Savan]

Hi,

I am creating Rad Menu dynamically. Following is the code. Even I tried following code in Page_Load().
But still its not working...

Why? Can anyone help me?


public partial class _Default : System.Web.UI.Page
{
    RadMenu menu;

  
    protected override void CreateChildControls()
    {
        base.CreateChildControls();
        menu = new RadMenu();
        menu.ID = "radmenucontrol";

        menu.Items.Add(new RadMenuItem("Google", "http://www.google.com"));
        menu.Items.Add(new RadMenuItem("Google1", "http://www.google.com"));
        menu.Items.Add(new RadMenuItem("Google2", "http://www.google.com"));
        menu.Items.Add(new RadMenuItem("Google", "http://www.google.com"));
        menu.Items.FindItemByText("Google").Items.Add(new RadMenuItem("Yahoo", "Default.aspx"));
        menu.Items.FindItemByText("Google").Items.Add(new RadMenuItem("Yahoo1", "Default.aspx"));
       
        this.Controls.Add(menu);       
        menu.ItemClick += new RadMenuEventHandler(menu_ItemClick);
    }

    void menu_ItemClick(object sender, RadMenuEventArgs e)
    {
        Response.Redirect("http://www.google.com");     
    }
}

Hi Savan,

I have found that you have set the NavigateUrl property which effectively disables the postbacks. Please check the following forum link which describes the possible solution for this.

Hi,
I followed thes steps written in following discussion
ItemClick event not firing

But it still not firing the event.

I got the where the problem is but dont know how to solve. Please help me!!!!

Note: I am working in SharePoint ( WSS 3.0 )

I am using "RadMenu.NET2" dll of version 4.4.6.0 which I placed in GAC.
I want to use this in a web part. But for example purpose I created one asp.net application and I am creating RadMenu dynamically.

The Revised code is

public partial class _Default : System.Web.UI.Page
{
    RadMenu menu = new RadMenu();     

     protected void Page_Init(object sender, EventArgs e)
    {
        menu.ItemCreated += new RadMenuEventHandler(menu_ItemCreated);        
    }

    protected override void CreateChildControls()
    {
        base.CreateChildControls();
        //menu = new RadMenu();
        menu.ID = "radmenucontrol";       
        menu.Items.Add(new RadMenuItem("Google", "http://www.google.com"));
        menu.Items.Add(new RadMenuItem("Google1", "http://www.google.com"));
        menu.Items.Add(new RadMenuItem("Google2", "http://www.google.com"));
        menu.Items.Add(new RadMenuItem("Google", "http://www.google.com"));
        menu.Items.FindItemByText("Google").Items.Add(new RadMenuItem("Yahoo", "Default.aspx"));
        menu.Items.FindItemByText("Google").Items.Add(new RadMenuItem("Yahoo1", "Default.aspx"));

        menu.ItemClick += new RadMenuEventHandler(menu_ItemClick);
        this.Controls.Add(menu);

       
       
    }

    void menu_ItemCreated(object sender, RadMenuEventArgs e)
    {
         e.Item.Attributes["NavigateUrl"] = e.Item.NavigateUrl;
         e.Item.NavigateUrl = "";
       
    }

    void menu_ItemClick(object sender, RadMenuEventArgs e)
    {
            Response.Redirect(e.Item.Attributes["NavigateUrl"].ToString());
    }
    
   }

But it does not work. So what I tried is, I registered reference of "RadMenu.NET2" in my .aspx page like
<%@ Register TagPrefix="rad" Namespace="Telerik.WebControls" Assembly="RadMenu.NET2" %>

And Added one radmenu control at design time. Added some Items and add menu click event also and it works. The menu click event is firing...

And I found that when I create RadMenu control dynamically it does not create following javascript code in html. I checked it in ViewSource.

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['form1'];
if (!theForm) {
    theForm = document.form1;
}
function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}
//]]>
</script>

and is also not creating two hidden controls
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
 <input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />

But when I create RadMenu at design time, it creates this hidden control and Javascipt also...

Can u please help me, how to solve this????

Thanks

Hi,

One another problem is there now.

The code that you have given works very fine.
When I add same code in SharePoint web part, it works there aslo.

But When I create a web control, add that web control in master page, then its not working, by registering that control like

<%@ Register TagPrefix="RadMenuControl " Namespace="RadMenuControl" Assembly="RadMenuControl, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f47633eb40d2fe0d" %>

When I do this, control comes in page, but event is not firing. I have a web part on the same page, with same code, and there event is firing.

Can you tell me why?

Thanks
Savan
