• Refactoring: I need to be able to move a page around without having to find every string reference to it
• No Reflection: It’s slow I don’t want to have to use it when redirects happen often.
• Parameters: I want to be able to pass parameters to a function and make that become part of the get request, I want the logic for that to exist on the page being redirected to as that is where the parameters are being used, this will also help with refactoring, the plain ole redirect logic however would just exist on a base class, don’t want to have to rewrite for every page.

I knew the ideal situation would be if I could somehow use the fact that web application projects use the folder hierarchy for its namespace convention and end up being able to redirect to the page ~/Users/UserDetails.aspx?UserId=14 with the following command Users.UserDetails.Redirect(14);

Here is how I did it:

I have a web application project, let’s call it MyProject.Web

I have two pages called UserDetails.aspx and UserList.aspx in the folder Users.

They both inherit from the following base class:

They follow this pattern:

namespace MyProject.Web.Users

{

public partial class UserDetails: BasePage<UserDetails>

{

public static void Redirect(int userId)

{

Redirect(“UserId=” + userId.ToString());

}

}

}

Now because UserDetails and UserList are in the same folder I can simply call UserDetails.Redirect(selectedUserId) on the UserList and UserList.Redirect() on the UserDetails.
The only real disadvantage is that it could confuse people who discover a Redirect method on their current page that they can’t use to make it to another page.
However it should be abundantly clear to everyone what you are doing when they see it already written.
Also every time you move a class, remove or add a parameter, it will break on compile time not at run time.

Comments and feedback welcome.

If you come across this problem make sure that your custom control implements the INamingContainer as well as the IPostBackEventHandler interfaces

Also make sure that your first argument to the __dopostback function is the unique id of your custom control (this.UniqueId)

Last night I was at the first meeting of the local alt.net book club, we’re currently going through a book called the art of unit testing. What I took from reading the first chapter and the discussion we had at the meeting was that you test your code already, your tests can be improved and unit testing will improve it. My first mistake was to confuse what unit testing was. I thought it was just automated testing. I had used a unit testing framework and that’s all that I had learnt from doing so. However once you start reading up on the best practices of testing you hear a different story.

Unit testing is testing a piece of logic as a unit isolated from all dependancies. That’s not the offical definition, it’s only designed to cover the bit that I msised. When you unit test a piece of code, you shouldn’t call other parts of your code. If necessary you should fake, mock or stub the rest of your logic in order to isolate that code properly. When you get the result of that test, you’ll then know whether that unit of logic is working or not.

Alternatively you could all it to call other units of logic and then you’ll know either that all is well or something somewhere in your code is broken. Which is fine if you have a small project that will never grow, because then you’ll only lose a small amount of time hunting down bugs gradually increasing as your grasp of the project slips over time. However if you have a large project you could easily lose days, it’s even worse when you have a whole team full of people that every time there is a failed test, the whole project doesn’t work and no one can proceed.

That’s what I took away from it, I’d recommend book clubs as a pain free way to get through technical books and I shall be using unit testing next chance I get.

We’ve got a 3rd party DLL that we use (not strong named) and I wanted to add it to the GAC. Alas! Only strong named assemblies are allowed in the GAC.

I’ve been trying figure this out for almost a week… couldn’t find much help on Google , so I thought I’d share.

Well, here is my solution (it works… not sure if it’s the best way though)

From a VS.NET command prompt, enter the following:

1. Generate a KeyFile

sn -k keyPair.snk

2. Obtain the MSIL for the provided assembly

ildasm providedAssembly.dll /out:providedAssembly.il

3. Rename/move the original assembly

ren providedAssembly.dll providedAssembly.dll.orig

4. Create a new assembly from the MSIL output and your assembly KeyFile

ilasm providedAssembly.il /dll /key= keyPair.snk

Viola!

You now have a strong named assembly.

If you are finding that you can’t click on the arrows on the Calendar Extender in IE 8 try using the following css.

.ajax__calendar_title{width:150px; margin:auto; padding:3px;}

It stops the calendar title from extending over the arrows.

So far I’ve seen two implementations of ASP.Net wrapper on JqGrid, one involves a httphandler and the other involves using a web service. Both add extra work onto the gridview/datasource pattern.

Instead I had the JqGrid use a Callback Event Reference (Page.ClientScript.GetCallbackEventReference()) with async (a parameter) set to true, this allowed me to call back directly to the custom asp.net JqGrid control instance and access the DataSource.

This is not ideal, as it passes the view state to the server first but it is the simplest and cleanest going from ASP.Net GridView to JqGrid.

Other useful information

Inherit CompositeDataBoundControl and add the attribute
[PersistenceModeAttribute(PersistenceMode.InnerProperty)]
public DataControlFieldCollection Columns { get; set; }
in order to get
<My:Grid>
<columns>
<asp:BoundField….
working

implement CallbackEventHandler otherwise the Page.ClientScript.GetCallbackEventReference() won’t work.

I’d recommend using Rick Strahl’s ClientScriptProxy for registering your Javascript, it solves the problem of whether the page your control ended up on has a scriptmanager. Find that here: http://www.west-wind.com/weblog/posts/10246.aspx

Here are some pages I found helpful on JqGrid: (if I find any more I’ll add them)
