        .easyMenu
        .easyMenuItemContainer
        .easyMenuItem
        .easyMenuItem a

11. How to use the menu programatically?

In the downloadable zip file containing the examples for EasyMenu, you will find examples of how to use EasyMenu from code (programatically), by creating the same functionality as the examples with declarative asp.net code.

Note: you could try to see the code from examples with the same name in parallel in order to better understand how you can achieve the same functionality with code-behind. (e.g: aspnet_horizontal_1.aspx and cs_horizontal_1.aspx, cs_horizontal_1.cs)

12. How to add Easy Menu to the page?

You have created the Easy Menu control and added items along with configuration, still the menu does not appear on the page?
Check one of the following:
1. You have assigned a unique ID to the menu. (myEasyMenu1.ID = "myEasyMenu1")
2. You have set the AttachTo property, and also it is a valid control id. (myEasyMenu1.AttachTo = "div1") For more info, take a look at the AttachTo tutorial.
3. You have added it to the controls collection of the page or to any other placeholder. (Page.Controls.Add(myEasyMenu)))


Note: take a look at the examples in codebehind folder called vertical, horizontal, horizontal_1 since there you can see multiple menus on the same page.

13. I'm using more than one Easy Menu on the page but only the last one added is rendered?

Make sure you have assigned a unique ID to each menu. For example, use:
myEasyMenu1.ID = "myEasyMenu1"
myEasyMenu2.ID = "myEasyMenu2"

14. Where to put folder 'EMStyles' ?

To run examples put folder 'EMStyles' from zip file into 'C:\Inetpub\wwwroot'

You can also put it to any other location on your web server under the root folder.

Use web relative paths:
- If folder was placed in 'C:\Inetpub\wwwroot':
easyMenu.IconsFolder = "/EMStyles/Icons"
easyMenu.StyleFolder = "/EMStyles/Styles/Style1" 

- If folder was placed in 'C:\Inetpub\wwwroot\MyPath':
easyMenu.IconsFolder = "/MyPath/EMStyles/Icons"
easyMenu.StyleFolder = "/MyPath/EMStyles/Styles/Style1" 

- If folder was placed in the same folder with your aspx file:
easyMenu.IconsFolder = "EMStyles/Icons"
easyMenu.StyleFolder = "EMStyles/Styles/Style1"

17. How to add links to Menu Items ?

Menu Items have two properties that help you open new pages on click:
· Url - sets the page to be opened
· UrlTarget - the target frame to open the page

Url can be any URL of a page (relative or absolute), just like the href of a link.

UrlTarget can be:
  - the name of an existing frame or iframe in the page
  - _blank to open in a new browser window
  - _top to open in the top document of the current window
  - _self to open instead of the current page

19. What browsers are supported?

Easy Menu has been tested and works correctly under Internet Explorer, Netscape Navigator, Mozilla FireFox and Opera.


Note: Easy Menu might also work correctly under other browsers, but it has not been tested yet.

20. How to use Easy Menu in an ascx control?

Using Page.Controls.Add (em_1), we are actually asking the ascx control to add the Easy Menu control to its parent page. However, the control cannot modify its parent. To overcome this, we should simply need to modify the line:
Page.Controls.Add (em_1)
to
this.Controls.Add (em_1)


Note: Easy Menu only attaches to the items after the page loads so unless using frames or iframes, it will not matter that an EasyMenu found inside an ascx control would have to attach to items found in the master page.

21. Does Easy Menu work with ASP classic too, or only with ASP.NET?

Unfortunatelly this component does not work with ASP classic, only with ASP.NET.

22. How to make the background transparent?

You need to modify the .css file. Whenever we have a background and it applies, we need to set the background color transparent:
background-color: transparent;


Notes:
· We may also use filter for opacity instead of making the background transparent. For example, we may use:
      background-color: Black;
      filter: Alpha(Opacity=0); /* for IE */
      -moz-opacity: 0.6; /* for Firefox */
      opacity: .6; /* for Safari */
You won't get any errors using all lines at the same time.

23. Is Context Menu supported by the Opera browser?

Opera only supports MouseClick and MouseOver events for the ShowEvent property.

24. How to supress the Easy Menu from emitting IFRAME tags without SRC attributes?

Starting with version 2.5.11.0 of Easy Menu this problem is solved.
If for some reason we need to have the src of the iframe point to a certain page in a secured zone, we can use the property called securedPageUrl to set the url of this page.

25. How to use different styles for multiple Easy Menu on the same page?

If only one easymenu is visible at the same time you can do this by simply setting a different StyleFolder property for each Easy Menu.

For example:
<oem:EasyMenu id="Easymenu1" StyleFolder="/emstyles/styles/horizontal1">
and
<oem:EasyMenu id="Easymenu2" StyleFolder="/emstyles/styles/horizontal2">


If more than one easymenu is visible at the same time in the webpage, you need to use different css class names for the easymenu items.
To accomplish this you need to use CSSClasses and CSSClassesCollection properties.
More information on these properties you can find in server side documentation page.

For example:

For the first easymenu you don't need to do anything.

For the second easymenu on your webpage you need to add CSSClassesCollection property.
Second easymenu on your page has the css class names suffixed by "_1".

<oem:EasyMenu id="EasymenuMain" runat="server" ShowEvent="Always" StyleFolder="/emstyles/styles/example_1"
Position="Horizontal" CSSMenu="ParentMenu_1" CSSMenuItemContainer="ParentItemContainer_1" Width="330">
<CSSClassesCollection>
<oem:CSSClasses ObjectType="OboutInc.EasyMenu_Pro.MenuItem"
ComponentSubMenuCellOver="ParentItemSubMenuCellOver_1"
ComponentContentCell="ParentItemContentCell_1" Component="ParentItem_1"
ComponentSubMenuCell="ParentItemSubMenuCell_1"
ComponentIconCellOver="ParentItemIconCellOver_1" ComponentIconCell="ParentItemIconCell_1"
ComponentOver="ParentItemOver_1" ComponentContentCellOver="ParentItemContentCellOver_1" />
<oem:CSSClasses ObjectType="OboutInc.EasyMenu_Pro.MenuSeparator"
ComponentSubMenuCellOver="ParentSeparatorSubMenuCellOver_1"
ComponentContentCell="ParentSeparatorContentCell_1" Component="ParentSeparator"
ComponentSubMenuCell="ParentSeparatorSubMenuCell_1"
ComponentIconCellOver="ParentSeparatorIconCellOver_1" ComponentIconCell="ParentSeparatorIconCell_1"
ComponentOver="ParentSeparatorOver_1"
ComponentContentCellOver="ParentSeparatorContentCellOver_1" />
</CSSClassesCollection>
<Components>
<oem:MenuItem InnerHtml="Item1" ID="item1" />
<oem:MenuSeparator InnerHtml="|" ID="mainMenuSeparator1" />
<oem:MenuItem InnerHtml="Item2" ID="item2" />
<oem:MenuSeparator InnerHtml="|" ID="mainMenuSeparator2" />
<oem:MenuItem InnerHtml="Item3" ID="item3" />
<oem:MenuSeparator InnerHtml="|" ID="mainMenuSeparator3" />
<oem:MenuItem InnerHtml="Item4" ID="item4" />
</Components>
</oem:EasyMenu>

Also for the second easy menu you need to edit file style.css from the specified style folder by StyleFolder property, and add to the names of the classes "_1".

.ParentMenu_1
{
background-image: url(/emstyles/styles/horizontal1/margin.gif);
background-repeat: repeat-x; background-position: left bottom;
height: 30px;
padding-left: 1px;
padding-right: 1px;
}

.ParentItemContainer_1
{
background-image: url(/emstyles/styles/horizontal1/mid.gif);
background-repeat: repeat-x;
}

...

26. Where to set up properties like StyleFolder or UseIcons?

These properties must be set when we are declaring the Easy Menu. If we are declaring the Easy Menu in an .aspx file, then we have to set it like this:
<oem:EasyMenu id="Easymenu1" StyleFolder="/emstyles/styles/default" ...>

If you are using the Easy Menu in code behind, then you need to set them like this:

EasyMenu1 = new EasyMenu();
...
EasyMenu1.StyleFolder="/emstyles/styles/default"
...

where EasyMenu1 is the id of our Easy Menu.
