ModifyMenuItem event is deprecated. Use ModifyMenu event.
Description
The ModifyMenuItem event is executed for each menu item before the page is displayed in the browser. Use this event to modify or hide menu items.
Syntax
public XVar ModifyMenuItem(dynamic menuItem)
Arguments
menuItem
a menu item object.
Return value
True: a menu item is shown.
False: a menu item is hidden.
Applies to pages
All pages with the Menu items.
Methods
getLinkType()
gets the link type.
Note: The link types are: Internal (link to a page generated by ASPRunner.NET, e.g. List, Print etc.), External (link to any external web page), None (if menu item is not a link: for example, a group or separator).
getUrl()
gets the URL of an external link.
setUrl(url)
sets the URL of the link and makes it external.
getParams()
gets the parameters of an internal link.
setParams(params)
sets the parameters of an internal link. These parameters may be also set on the Choose page screen using the '...' button next to the List page.
Note: The parameters are a part of the link. E.g., if the parameters are foo=bar&bar=foo, the link is ...list?foo=bar&bar=foo.
setTitle(title)
sets the title of the link.
getTitle()
gets the title of the link.
getTable()
gets the table name that an internal link points to.
setTable(table)
sets the table name.
getPageType()
gets the page type (List, Add, etc.).
setPageType(pType)
sets the page type (List, Add, Search, Print, Report, Chart).
Example 1
Adding parameters to a menu item
if (menuItem.getLinkType() == "External")
menuItem.setUrl(MVCFunctions.GetTableLink("carsmodels", "list"));
else if (menuItem.getLinkType() == "Internal")
{
menuItem.setParams("id=30");
if (menuItem.getTable() == "carsmake")
menuItem.setTable("carsmodels");
}
else
{
return false;
}
return true;
Example 2
Hide some menu items based on the group of the authorized user. If the menu item is a link to an internal application page, you can assign the table permissions.
However, if the menu item is an external link, you show/hide it directly in this event.
if (XSession.Session["GroupID"] != "manager")
{
var title = menuItem.getTitle();
if (title == "Yahoo Finance")
{
return false;
}
}
return true;
Example 3
Display a record counter next to each menu item. The code checks if the menu item is an internal table or view and adds the number of records to the menu item title.
if (menuItem.getLinkType() == "Internal" && menuItem.getPageType() != "WebReports")
{
var pset = new ProjectSettings( menuItem.getTable() );
var table = pset.getOriginalTableName();
var rs = CommonFunctions.db_query("select count(*) as c from " + CommonFunctions.AddTableWrappers(table).ToString(), null);
var data = CommonFunctions.db_fetch_array(rs);
if (data)
menuItem.setTitle(String.Format("{0} ({1})", menuItem.getTitle(), data["c"]));
}
return true;
Example 4
Hide some menu items in the Mobile mode
if (menuItem.getTable() == "Cars" && CommonFunctions.MobileDetected()) {
return false;
}
return true;
