MenuItem of 2nd and 3rd Menus ..Server Click Event not firing

[Neal]

Hi,  some help needed please

I have 3 menus (expanded/outlook type) in a Nav Pane and Loading into a content Pane.

I have the first menu's server side click working using  (C#..override onInit  etc working fine)
the other two however,..applying the same logic however do not recognise and fire their respective set up click events.
What am I missing?



I am using Telerik Q4 2006 ASPNet 2.

The code is  beneath (I have excluded the 3rd menu for brevity,..but should be same logic problem as second menu)

The FindControl for each menu is also fine,..just the click event for menus 2 and 3 not firing

Thanks
Neal

Hello Neal,

Could you verify (with the aid of the debugger) that your code successfully attached the event handlers? I suspect the menu instances remain "null" and the event subscription code never executes.
You should use the following syntax to access child controls of templated items:

RadMenu menu = (RadMenu)RadPanelbar1.Items[0].Items[0].FindControl("RadMenu1");

Accessing the Controls collection of the panelbar or items may lead to unexpected results because the panel items are controls themselves.

I hope this helps,

Thanx,  the first one was always correct
i.e.
RadMenu menu = (RadMenu)RadPanelbar1.Items[0].Items[0].FindControl("RadMenu1");


the second needed   "Controls[1]."

RadMenu

MidRadMenu =(RadMenu)this.RadPanelbar1.Controls[1].Controls[0].FindControl("Radmenu2");

but , it causes IE to open a new window now (no postback/runat server ....with
 "javascript:__doPostBack('RadPanelbar1$p1$p0$Radmenu2','RadPanelbar1$p1$p0$Radmenu2$m0')  in the AddressBar and
with the Message  "Internet Explorer cannot display the webpage"

Hello Neal,

I have prepared a sample web site which works fine on my end (using the latest official Q1 2008 release). Please find it attached.

Hi and Thanks,
but no cigar unfortunately.

I did change my C# to Items[].FindControl  (after removing the extra unneccessary RadpanelItem.  and each of the 3 menus were found (and referenced) correctly.

I removed my RadAjaxManager from the aspx,..no Luck either.
The CodeBehind for the Click Events on the 2nd and 3rd menu are not firing,..
The __DoPostback java script appears immediately after clicking, in the address bar.

May be the parameters passed to the postback before it gets to the Server code are the problem?
eg Selecting the 2nd Menu in the RadPanelBar1

"javascript:__doPostBack('RadPanelbar1$p1$p0$Radmenu2','RadPanelbar1$p1$p0$Radmenu2$m0')  in the AddressBar with the Message  "Internet Explorer cannot display the webpage" in the body

or the 3rd menu in the RadPanelbar_RP  (which is $p0 $p0..
i.e. Item[0].item[0].Radmenu3

javascript:__doPostBack('RadPanelbar_RP$p0$p0$Radmenu3','RadPanelbar_RP$p0$p0$Radmenu3$m0')

Only Menu1 fires and loads correctly...weird
At this point in terms of aspx , the only difference is I have my RadPanelBar inside an asp:Panel, 
Maybe its a version thing,..  I use Q4 2006?

Can you try it in version Q4 1.6??

TIA
Neal

Hello Neal,

Removing the Target property of the second menu items seems to fix the issue.
