Configuring Multiple Sitemaps in .NET

December 7, 2007 at 1:12 pm (.NET, ASP.NET, Web Design)

Sitemaps are used to describe the structure of the site so that the site navigation controls such as menu, treeview etc can use it to display the site structure properly. Generally the owner of the site will want to display a separate navigation for anonymous and logged users. For this the menu structure will vary. In this case we can use multiple sitemaps to display the appropriate menu based on user.

For using multiple sitemaps you need to configure the sitemap in the web.config file. We will learn this through an example. Suppose we need to site that allows the logged user to buy the product and the anonymous user is allowed only to browse the product. For this we need to display buy & browse in the menu for the logged user and browse for anonymous user. To implement this we can use multiple sitemaps.

Create a new website and add the two sitemaps for this namely logged and anonymous. In the logged.sitemap add two sitemap nodes, Browse and Buy. In the anonymous.sitemap create only one sitemap node, Browse. Read the rest of this entry »

Designing Menu using Sitemap and asp menu control

December 6, 2007 at 1:25 pm (.NET, ASP.NET, Web Design)

Menu can also be designed using the sitemap and the asp menu control. For this first the structure of the menu need to be designed first. Then web.sitemap for the menu is designed. web.Sitemap is an XML file that should be stored in the root directory of the website. It contains a root node <siteMapNode>. This node in turn contains multiple sitemap node for each menu item. Sitemap node has the following important attributes title, url and description.

Title : specifies the text need to be displayed on the page.

Url : Specifies the link path.

description : Specifies the tooltip text.

Part of web.sitemap is displayed below:-

<?xml version=”1.0″ encoding=”utf-8″ ?>
<siteMap xmlns=”; >
<siteMapNode url=”” title=”Tour Resources” description=”Tour Resources” >
<siteMapNode url=”” title=”Route Notes &amp; Tour info” description=”Route Notes and Tour info”>
<siteMapNode url =”../et_uk_rns.aspx” title =”Route Notes ET” description =”Route Notes ET”/>
<siteMapNode url =”../gat_rns.aspx” title =”Route Notes GAT” description =”Route Notes GAT”/>
<siteMapNode url =”../tour_summaries.aspx” title =”Tour Summaries” description =”Tour Summaries”/>
<siteMapNode url =”../tour_schedules.aspx” title =”Tour Schedules” description =”Tour Schedules”/>
<siteMapNode url=”../educationlm.aspx” title=”Educational Material” description=”Educational Material”></siteMapNode>
<siteMapNode url=”” title=”Free Time Posters” description=”Free Time Posters”>
<siteMapNode url =”../et_cityins.aspx” title =”Free Time Posters ET” description =”Free Time Posters ET”></siteMapNode>
<siteMapNode url =”../gat_cityins.aspx” title =”Free Time Posters GAT” description =”Free Time Posters GAT”></siteMapNode>
<siteMapNode url =”../cb_cityins.aspx” title =”Free Time Posters CB” description =”Free Time Posters CB”></siteMapNode>
<siteMapNode url=”../extrawts.aspx” title=”Walking Tours” description=”Walking Tours”></siteMapNode>
<siteMapNode url=”” title=”TD Travel” description=”TD Travel”>
<siteMapNode url =”../tdovernight.aspx” title =”TD Overnights” description =”TD Overnights”></siteMapNode>
<siteMapNode url =”../tdflights.aspx” title =”TD Flights” description =”TD Flights”></siteMapNode>

Then in the page where the menu need to be displayed, we need to use asp SiteMapDataSource control. Then we can use asp menu control and point the DatasourceId to the above SiteMapDataSource.

Sample Code:-

<asp:Menu DataSourceID=”SiteMapDataSource1″ ID=”Menu1″ runat=”server” BackColor=”#FFFFFF” BorderColor=”#F57F2C” BorderWidth=”1px” DynamicHorizontalOffset=”2″ StaticSubMenuIndent=”10px” >
<DynamicMenuStyle BackColor=”White” BorderColor=”#F57F2C” BorderWidth=”1px” />
<StaticMenuItemStyle BorderColor=”#F57F2C” BorderWidth=”1px” HorizontalPadding=”5px” VerticalPadding=”2px” />
<DynamicMenuItemStyle BorderColor=”#F57F2C” BorderWidth=”1px” HorizontalPadding=”5px” VerticalPadding=”2px” Font-Bold = “true” Font-Italic = “true” Font-Names = “verdana” Font-Size = “small” />
<%– <StaticSelectedStyle BackColor=”#F57F2C” BorderColor=”#F57F2C” BorderWidth=”1px” ForeColor=”White” />
<DynamicSelectedStyle BackColor=”#F57F2C” BorderColor=”#F57F2C” BorderWidth=”1px” ForeColor=”White”/> –%>
<StaticHoverStyle BackColor=”#F57F2C” BorderColor=”#F57F2C” BorderWidth=”1px” ForeColor=”White” />
<DynamicHoverStyle BackColor=”#F57F2C” ForeColor=”White”/>
<asp:SiteMapDataSource ID=”SiteMapDataSource1″ Runat=”server” ShowStartingNode=”false”/>

ShowStartingNode : It specifies that the sitemapdatasource should not display the root node in the menu.


SiteMapDataSource will get the data from web.sitemap automatically.

Static menu using asp:menu control

December 6, 2007 at 12:25 pm (.NET, ASP.NET, Web Design)

Last week i explored asp menu control and found it very useful to build the menu. The asp menu control can be used to display the menu vertically or horizontally. Menu items need to be displayed under the <items> section. Each menuitem is specified using the <asp:menuitem> tag. Multiple level menus can be easily designed using the asp menu control. The code i designed for the menu is shown below:-

<asp:Menu ID=”Menu1″ Orientation = “Vertical” runat=”server” BackColor=”#FFFFFF” BorderColor=”#F57F2C” BorderWidth=”1px” DynamicHorizontalOffset=”2″ StaticSubMenuIndent=”10px” >

<DynamicMenuStyle BackColor=”White” BorderColor=”#F57F2C” BorderWidth=”1px” />

<StaticMenuItemStyle BorderColor=”#F57F2C” BorderWidth=”1px” HorizontalPadding=”5px” VerticalPadding=”2px” />

<DynamicMenuItemStyle BorderColor=”#F57F2C” BorderWidth=”1px” HorizontalPadding=”5px” VerticalPadding=”2px” Font-Bold = “true” Font-Italic = “true” Font-Names = “verdana” Font-Size = “small” />

<StaticSelectedStyle BackColor=”#F57F2C” BorderColor=”#F57F2C” BorderWidth=”1px” ForeColor=”White” />

<DynamicSelectedStyle BackColor=”#F57F2C” BorderColor=”#F57F2C” BorderWidth=”1px” ForeColor=”White”/>

<StaticHoverStyle BackColor=”#F57F2C” BorderColor=”#F57F2C” BorderWidth=”1px” ForeColor=”White” />

<DynamicHoverStyle BackColor=”#F57F2C” ForeColor=”White”/>

<asp:MenuItem Text=”Page 1″ NavigateUrl=”Page1.aspx”>
<asp:MenuItem Text=”Page 1-1″ NavigateUrl=”Page1-1.aspx”/>
<asp:MenuItem Text=”Page 1-2″ NavigateUrl=”Page1-2.aspx”/>
<asp:MenuItem Text=”Page 2″ NavigateUrl=”Page2.aspx”>
<asp:MenuItem Text=”Page 2-1″ NavigateUrl=”Page2-1.aspx”/>
<asp:MenuItem Text=”Page 2-2″ NavigateUrl=”Page2-2.aspx”/>
<asp:MenuItem Text=”Page 3″ NavigateUrl=”Page3.aspx”>
<asp:MenuItem Text=”Page 3-1″ NavigateUrl=”Page3-1.aspx”/>
<asp:MenuItem Text=”Page 3-2″ NavigateUrl=”Page3-2.aspx”/>


you can view the menu i designed below:-

ReDim Statement

June 18, 2007 at 6:07 am (.NET, ASP.NET)

ReDim statement is used to resize an existing array.

Example :-

Dim names(2) as String = {“james”,”jack”,”rose”}

now if we need to add another name then we can resize the array using the ReDim statement.

ReDim names(3)

In the above example the old data in the array will be deleted when redimmed, We can use the Preserve keyword to retain the old data while ReDimming.

ReDim Preserve names(3)

What it actually does is that it copies the old data into the new array with the new size and then delete the old one thereforel it is better to avoid using ReDim statement. Instead you can use ArrayList if the exact size is not known.

 2.Select File->New Project to open the New Project Dialog box.

3. From the Project Types pane, select Setup and Deployment Projects.From the Templates pane, select Web Setup Project.

4. Change the default name of the project. In this case, change it to “SampleVBDeploy.”

5. Click OK to complete the process. The project is added in the SolutionExplorer window. Also, a File System editor window appears to the left.The editor window has two panes. The left pane displays different items. The right pane displays the content of the itemselected in the left pane.

6. Select Web Application Folder in the left pane of the File System editor window
7.Then,from the File menu select Add -> Existing Website to open the Add Existing WebSite Dialog box.Choose the Web Application that you want to Deploy(In our case its SampleVB).The Web Application will be added in the Solution Explorer Window 8.Then, from the Action menu, select Add ® Project Output to open the Add Project Output Group dialog box.

9. Verify that SampleVB is selected in the Project drop-down list. Then,select Content Files from the list.

10. Click OK. The content files of the SampleVB project are added to the solution.

11. Select Web Application Folder in the File System editor and select Properties Window from the View menu to open the Properties window.

12. Set the VirtualDirectory property to a folder, <folder name>, that would be the virtual directory on the target computer where you want to install the application. By default, this property is set to SampleVBDeploy,which is the name of the Web Setup project that youadded. In this case, set the property to DeployedApplication.

Caution The <folder name> should be a new folder name and should not already exist on the target machine. Otherwise, the contents in the folder will be overwritten.
13. In the same Properties window of the Web Application Folder, set the DefaultDocument property to Default.aspx. This property is used to set the default Web Forms page for the application.

14. Build the solution by selecting Build Solution from the Build menu.

15. After the solution is built successfully, a SampleVBDeploy.msi file is created in the Debug directory of the Web Setup project. The default path is \documents and settings\<login name>\My Documents\VisualStudioProjects\SampleVB\SampleVBDeploy\Debug\

16. Copy the SampleVBDeploy.msi file to the Web server computer (c:\inetpub\wwwroot) where you want to deploy the application.

17. Double-click the SampleVBDeploy.msi file on the target computer to run the installer.

Note To run the installer, you must have the install permissions on the computer. And, to install to the Web server, you must have IIS permissions.

After the installation is complete, you can run your application on the target computer. Todo so, start Internet Explorer and enter http://<computer name or IP Address>/DeployedApplication in the address box.
