Combo Control

Introduction

This is a control which will help to generate Tabs , Menus, Slider bars, and Tree views. Just in time dynamically from XML.

Background

We see many web pages with lots of controls. Most of the controls available in the market are quiet expensive and they do only one work (if it is a menu control we cant use for tab). This control has all the built in features including the security. For example, the user may want some of the items in the tab should be visible to a particular set of users say administrators and some less important to the common users. In that case this plays a important role.

This control is very easy to use. The control exposes some public properties to set the data, look 'n' feel and events for the panel. By setting these properties, the collapsible panel can be used to group information very nicely.

Using the code

The user control has four public properties:

Controltype = To mention the type of control (tab, tree, panel, menu).
Display = To set alignment of the control (only to Controltype =menu).
PageTitle = To set the pagetitle (only to Controltype = tab).
MainMenuSelected = To set the Main menu (only to Controltype = tab).
SubMenuSelected = To set the Submenu selected (only to Controltype = tab).
ImageUrl = To set the Image in the tree (only to Controltype = tree).

<%@ Register TagPrefix="CONTROL" Namespace="Controls" Assembly="FOURINONE"%>
 
// for tab
<CONTROL:FourinOne runat="server" PageTitle="Congress Type" Controltype="tab" 
 MainMenuSelected="2" SubMenuSelected="1" />
 
// for tree
<CONTROL:FourinOne runat="server" Controltype="tree" />
 
// for panel bar
<CONTROL:FourinOne runat="server" Controltype="panel" />
 
// for menu - horizontal
<CONTROL:FourinOne runat="server" Controltype="menu" Display="h" />
 
// for menu - vertical
<CONTROL:FourinOne runat="server" Controltype="menu" Display="v" />

For generating the menu, tree, panel, tab dynamically the xml should be of the form

<Menu>
 <MainMenu Label="Registration" BaseURL="SearchCongress.aspx" MenuID="8"
  MainSecurity="AM" MenuSequence="1" ImageUrl="xp_documents.gif">
  <SubMenu Label="Search" URL="SearchCongress.aspx" MenuID="8"
  Security="AM" SubMenuID="9" SubMenuSequence="1" ImageUrl="xp_documents.gif"/>
 <SubMenu Label="Add Company" URL="CompanyDetails.aspx" MenuID="8"  
  Security="A" SubMenuID="6" SubMenuSequence="4" ImageUrl="xp_documents.gif"/>
   <SubMenu Label="New Order" URL="NewOrder.aspx" MenuID="8" Security="AM" 
  SubMenuID="7" SubMenuSequence="5" ImageUrl="xp_documents.gif"/>
 </MainMenu>
 <MainMenu Label="Maintenance" BaseURL="Congress.aspx" MenuID="6" 
  MainSecurity="A" MenuSequence="4" ImageUrl="xp_documents.gif">
   <SubMenu Label="Congress Type" URL="Congress.aspx" MenuID="6" Security="A" 
  SubMenuID="1" SubMenuSequence="1" ImageUrl="xp_documents.gif"/>
   <SubMenu Label="Event Type" URL="EventType.aspx" MenuID="6" Security="A" 
  SubMenuID="2" SubMenuSequence="2" ImageUrl="xp_documents.gif"/>
   <SubMenu Label="Sales Type" URL="SalesType.aspx" MenuID="6" Security="A" 
  SubMenuID="3" SubMenuSequence="3" ImageUrl="xp_documents.gif"/>
   <SubMenu Label="Venue" URL="CongressVenue.aspx" MenuID="6" Security="A" 
  SubMenuID="4" SubMenuSequence="4" ImageUrl="xp_documents.gif"/>
   <SubMenu Label="Office" URL="Office.aspx" MenuID="6" Security="A" 
  SubMenuID="6" SubMenuSequence="6" ImageUrl="xp_documents.gif"/>
   <SubMenu Label="Sales Person" URL="SalesPerson.aspx" MenuID="6" Security="A" 
  SubMenuID="7" SubMenuSequence="7" ImageUrl="xp_documents.gif"/>
   <SubMenu Label="Tax Rate" URL="TaxRate.aspx" MenuID="6" Security="A" 
  SubMenuID="8" SubMenuSequence="8" ImageUrl="xp_documents.gif"/>
   <SubMenu Label="User" URL="User.aspx" Security="A" MenuID="6" 
  SubMenuID="9" SubMenuSequence="9" ImageUrl="xp_documents.gif"/>
   <SubMenu Label="Option Type" MenuID="6" URL="PriceOption.aspx" Security="A" 
  SubMenuID="10" SubMenuSequence="10" ImageUrl="xp_documents.gif"/>
 </MainMenu>
</Menu>

The MainSecurity attribute in the MainMenu node and Security attribute in the SubMenu node are used to implement the security in displaying the menu items.

To implement security in this control keep the UserType in the session for example (A for administrator) when the user logs on to the system. By comparing the value in session the security is implemented.

private bool isAuthorised(string sSecString, string sSecType){
  return(sSecString.IndexOf(sSecType)>=0);
 }

The isAuthorized method returns true if the user is authorized to view that page else it return 0. For exmple I have taken two users Administrator (A) and Moderator (M). I have mentioned the pages that can be viewed only my administrator as (A) and pages that can be viewed by both of them as (AM).

The menu can be configured using web.config.

      <add key="MenuXMLPath" value="/helper/" />
      <add key="MainMenuFontColor" value="#ffffff" />
      <add key="MainMenuShadowColor" value="#999999" />
      <add key="MainMenubGColor" value="#000088" />
      <add key="MainMenuMouseoverColor" value="#000088" />
      <add key="SubmenuBgColor" value="#cfd3d8" />
      <add key="SubmenuMouseoverColor" value="#ffffff" />
      <add key="SubmenuBorderColor" value="#0000cc" />
      <add key="SubmenuFontColor" value="#000000" />
      <add key="SubmenuMouseOverFontColor" value="#000000" />
      <add key="SubmenuShadowColor" value="#666666" />
