Re: Expanding MenuItem with OnMouseOver

Ok,

no i solved the problem with the use of a template definen in the aspx-page. At the event OnRowDataBound i check if the user is logged in. If not, the Menu-Item is set to enabled = false.

On the clientside i extended the onmouseover method and check if the event.srcItem is enabled or disabled. So i only display the info-div if the item is disabled.

There might be better and cleaner ways to do this, but this one is ok for me.

Thank You

Hi,

i think this is the right way. But i am stuck again.

what i want to do is the following:

if(user is logged in)
{
  staticItemTemplate myItemtemplate = new staticItemTemplate();
  // fill the Template with <a href... onmouseover=...>
  
  // bind the Template to the Menu
  myMenu.staticItemTemplate =  myItemTemplate;
}
else
{
  // use no special staticItemTemplate
}

Can anyone tell me how to create staticItemTemplates programatically?

Thanx

not sure, cause I haven't tried, but maybe you can add Attributes to a menuitem, if you declare the menuitems either statically or dynamically, as long as you have a reference to the menuitem ID.

you cannot add Attributes to a MenuItem class, but you can with the parent Menu Class.

you can try this out in your handler

menuName.Attributes [ "onmouseover" ] = "javascript:alert('Hello World!')";

Thank you for the quick reply,

but i have to check if the user is logged in or not. And so i have to set the onmouseover and onmouseout from code-behind if the user is not logged in. If the user is logged in, i don't need the onmouseover...

one way is to use templates

an example for a <dynamicitemtemplate> would be something like

   <asp:menu id="menu1" runat="server" datasourceid="siteMapDataSource1">
      <dynamicitemtemplate>
            
         <img src="/aspxtreme/shared/wink.gif"
            width="15" height="15" border="0" alt="">
         <asp:label id="menuItemLabel" runat="server"
            text='<%# eval( "Text" ) %>'
            onmouseover="whatever ( )"
            onmouseout="whichever ( )" />
            
      </dynamicitemtemplate>
   </asp:menu>

<asp:sitemapdatasource id="siteMapDataSource1" runat="server" />

Expanding MenuItem with OnMouseOver

Hi,
i have the following problem:

I am using a asp:menu Control for Navigation. At the MenuItemDataBound-Event I check if the user is logged in. If the user is logged in, i do nothing (menu-item is enabled and contains a selectable submenu). If the user is not logged in I disable the menu-item and would like to add a clientside onmouseover and onmouseout to show a div containing explanation-text.
But i don't know how to add these clientside event-handlers to the menu-item. I tried to cast the e.Item to an htmlAnchor, doesn't work. Someting like this:

( (HtmlAnchor)e.Item ).Attributes.Add( "onMouseOver", "showHint();" );
( (HtmlAnchor)e.Item ).Attributes.Add( "onMouseOut",  "hideHint();" );

Anybody any Idea?
