Put 4 Links In The Sidebar Of Master Page Which Every Other Form (content Page) In Web Application Inherits - C# / Visual Studio 2008

Apr 3, 2011

I want to have 4 links in the sidebar of master page which every other form (content page) in my web application inherits.

<table>
<tr>
<td width= "150px">
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
<asp:Menu runat="server" ID="MainMenu1" CssClass="MasterContent" StaticSubMenuIndent="30px">
<Items>
<asp:MenuItem Text="My Software" NavigateUrl="~/MySoftware.aspx"></asp:MenuItem>
<asp:MenuItem Text="Check Out" NavigateUrl="~/CheckOut.aspx"></asp:MenuItem>
<asp:MenuItem Text="View Shopping Cart" NavigateUrl="~/ShoppingCart.aspx"></asp:MenuItem>
<asp:MenuItem Text="Continue Shopping" NavigateUrl="~/Start.aspx"></asp:MenuItem>
</Items>
</asp:Menu>
</asp:ContentPlaceHolder>
</td>
<td width="900px">
<asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server">
</asp:ContentPlaceHolder>
</td>
</tr>
</table>

This is the content in the master page as you can see there are 4 menu items i tried to form as sidebar and i tried to inherit in home.aspx(one of the content pages) as follows:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Start.aspx.cs" Inherits="WebStore._Start"
MasterPageFile="~/Webstore.Master" %>
<asp:Content ID="StartSideBar" runat="server" ContentPlaceHolderID="ContentPlaceHolder1">

But unfortunately the sidebar is not at all getting displayed. I know i'm doing fundamentally wrong some where. My intention is to have web pages to have sidebar like this. It is a screenshot of my intended page.

Creating A Template Item From A Web Form And Auto Generating The Inherits Page Directive?

Jan 27, 2010

OK, so I'm trying to create a template item from a web form.

I have referenced this article: [URL] and it exports the template and installs it fine.

When you try and use the template item within a project though it leaves the inherits="_Default" in the page directive like shown below:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="FormTemplateDev.aspx.cs" Inherits="_Default" %>

So it thinks all the new template items use the original form name pre-template generation. This is an issue in the code behind too as shown here:

public partial class _Default : System.Web.UI.Page

I have seen example of passing paramater strings through but havent managed to get anything to compile. I found something like below:

public partial class $safeitemname$ : System.Web.UI.Page

This was the link to the list of available template parameters i found:

Project Template Parameters

How To Create A Custom Class That Inherits From System

Apr 22, 2010

I wanted to create a custom class that inherits from System.Exception and adds a few properties and methods specific to the project.

The issue I'm seeing is that a standard try/catch block catches generic Exception class and the compiler thinks that converting that to my custom class is OK. However, at runtime if the actual error is something else like a a System.Net.WebException for instance, then at runtime it will not convert to my custom class. Then my own error catch throws an InvalidCastException.

Obviously the one thing I don't want to happen is to have my error logging methods throw errors on their own...

So, how can I convert ANY exception to something that my custom class can use?

Here's a code example:

Csharp Code:

[code]....

Now, this code builds just fine... VS2008 and VS2010 have no issue with converting an "Exception" to "MyErrorClass", but at runtime it certainly doesn't like converting a "WebException" to "MyErrorClass"...

Set The Inherits Attribute Of An ASPX Page Directive To A Class In An Arbitrary Assembly?

Feb 24, 2011

Is it possible to set the Inherits attribute of an ASPX Page directive to a class in an arbitrary assembly?

I need to modify an ASP.NET (1.1) application for which the source code was lost. In a new assembly (foo2.dll) I've created a replacement code-behind class that derives from the original class in the site's code-behind assembly (foo.dll). It seems easy enough to set the Inherits attribute of the Page directive to the new class name, but when I do that the web server gives me Could not load type 'Foo2.checkout2'. I am referencing the new assembly in the <assemblies> section of Web.config.

I don't see anything in the documentation to indicate that this scenario is unsupported, but I'm not certain that it is, either.

Original

<%@ Page Inherits="Foo.checkout" language="c#" Codebehind="checkout.aspx.cs" AutoEventWireup="false" %>

New

<%@ Page Inherits="Foo2.checkout2" CodeFile="checkout2.aspx.cs" CodeFileBaseClass="Foo.checkout" language="c#" Codebehind="checkout.aspx.cs" AutoEventWireup="false" %>

Duplicate System.Web.UI.AsyncPostBackTrigger Controls Keep Getting Inserted Automatically - Causing Parser Errors

Apr 8, 2010

I have an update panel with a number of [asp:AsyncPostBackTrigger...] controls, and everything was working fine. But now, something keeps inserting duplicate AsyncTriggers, and instead of simply being [asp:AsyncPostBackTrigger...] controls they're [System.Web.UI.AsyncPostBackTrigger...] controls, and I get parser errors as a result. So I delete the duplicate triggers, and they get re-inserted within a few minutes, seemingly randomly.

There is also a Global.asax error catcher that works fine in other cases, but in the Page Method is not being catched.why a Page Method and System.Diagnostics do not play well together?

Web Forms :: To Create Aspx Page And Automatically Update Page Title?

May 20, 2010

Every time I create a new aspx page and add some new photos and text, after I finish, I have to update page title, Web.sitemap, Sitemap.xml to feed search engines, static sitemap.aspx page, add photos to proper folders, update database to display feeds etc, and I have to remember to upload all new files including links to any new pdfs....This routine eats my time and drives me crazy.

I was wondering if there is such interface, where you need to create only 1 aspx page, for example "Articles" which can populate Texts, photos etc into pre-defined sections, but at the same time it displays with different URL's, so there is a permanent link to it. After you finish it creates a title automatically, based on article title, populates Web.sitemap - does all the dirty work. Similar to how blog engines, Joomla and Drupal work.
