Call parent window’s javascript function from child window


Hi, I stuck with one requirement as describe in title and after searching for the solution, I found how can I call javascript function of the parent window whereas I am working with the child window. Here is the solution for you all.

Write below function of javascript in your parent window. We will call it later from the child.

    <script language=”javascript” type=”text/javascript”>
    function ParentWindowFunction()
    {
        alert(‘Hi, At least someone has called me from the child window’);
        return false;
    }
    </script>

Write the below code in your child window

    <script language=”javascript” type=”text/javascript”>
    function CallParentWindowFunction()
    {
        window.opener.ParentWindowFunction();
        return false;
    }
    </script>

You can call above function from a button click event like
    <input type=”button”  name=”btn1″ value=”Call Parent Window Function”onclick=”javascript:return CallParentWindowFunction();”/>

That’s it. Now by clicking on this child window’s button you can call a function resides in parent window.

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

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).

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...
