If I put alert() message then my javascript works fine otherwise script is not working


When you deal with the javascript and when you are using any form elements of the page in the script then you better make sure that your whole page gets load first. The form elements that you are using into the script will only get used until the page loads completely.
I have faced one situation where I was using popup window and was transferring the data of parent window to the opened popup. I have created one function into the popup window which will set some values into the text elements of the popup. I am calling this function from the parent window by passing some arguments to that function.
Now what happen is, when I am calling this function by putting some ‘alert()’ messages into the caller function and called function then the script is working fine for me. And when I am removing the ‘alert()’ message box from the script, the script stop working.
When I have analysis the script and debug it, I found that when I am calling a popup function from my parent window, the function did not set values into the text elements of the popup. This is because the popup window is not loaded completely. When I am putting an ‘alert()’ message box, the popup window gets sufficient time to load while I am busy clicking on the OK button for the alert message.
Thats it… I found that I was writing the script for the form elements which are not yet loaded into the popup and thats why I am getting this issue. I have resolved this issue by calling the javascript function of the popup only after it gets loaded completely.
If you found any similar issue then you can discuss here, I will try to solve it out.
Happy Programing!

Tip/Trick: Fix Common SEO Problems Using the URL Rewrite Extension

Search engine optimization (SEO) is important for any publically facing web-site.  A large % of traffic to sites now comes directly from search engines, and improving your site’s search relevancy will lead to more users visiting your site from search engine queries.  This can directly or indirectly increase the money you make through your site. This blog post covers how you can use the free Microsoft  URL Rewrite Extension  to fix a bunch of common SEO problems that your site might have.  It takes less than 15 minutes (and no code changes) to apply 4 simple  URL Rewrite  rules to your site, and in doing so cause search engines to drive more visitors and traffic to your site.  The techniques below work equally well with both ASP.NET Web Forms and ASP.NET MVC based sites.  They also works with all versions of ASP.NET (and even work with non-ASP.NET content). [In addition to blogging, I am also now using Twitter for quick updates and to sh...

ASP.NET MVC - Set custom IIdentity or IPrincipal

Here's how I do it. I decided to use IPrincipal instead of IIdentity because it means I don't have to implement both IIdentity and IPrincipal. Create the interface interface ICustomPrincipal : IPrincipal { int UserId { get ; set ; } string FirstName { get ; set ; } string LastName { get ; set ; } } CustomPrincipal public class CustomPrincipal : ICustomPrincipal { public IIdentity Identity { get ; private set ; } public bool IsInRole ( string role ) { return false ; } public CustomPrincipal ( string email ) { this . Identity = new GenericIdentity ( email ); } public int UserId { get ; set ; } public string FirstName { get ; set ; } public string LastName { get ; set ; } } CustomPrincipalSerializeModel - for serializing custom information into userdata field in FormsAuthenticationTicket object. public class CustomPrincipalSerializeMode...

linq orderby multiple columns dynamically

So, it's been a while, but I thought I take moment and do my annual blog post ;). I've been playing around with  ASP.NET MVC  and the Linq stuff for  NHibernate  recently. I was in need of an OrderBy extension method that could take a SQL-Like OrderBy string and sort a IQueryable<> or IEnumerable<> collection. I wrote up an implementation that worked, but I just wasn't satisfied with its internals (quite a bit of reflection to get the correct type to construct a LambdaExpression, etc) At any rate, I couldn't leave well enough alone, and, after a bit of Googling, I ran across this  StackOverflow  answer about Dynamic LINQ OrderBy . The extension method wasn't exactly what I was looking for, but that ApplyOrder method is slick, and solved the portion of my implementation that was bothering me. So, I though I would post up my version in case anybody finds it useful. It handles the following inputs: list.OrderBy( "SomeProperty" ); list.Ord...
