DevLog

In this article I explain in detail an extended GridView control developed based on the GridView control that ships with ASP.NET 2.0. Also discussed are important features of this new GridView: the built-in context menu row-based and the Filter textbox to filter the GridView's rows.

A very common question on the ASP.NET forums is how to do expression databinding on the ASPX page.

The ASP.NET allows you to use 3 different binding expressions:

1- <% %>
You can use the above expression to execute some C#/VB.NET code as follows:

<% Response.Write("Hello World"); %>

Which will print out "Hello World" on the page.

2- <%# %>
This expression can be used to execute any property, collection, expression, or method result on the ASPX page.

1. <%# CustomerID %> will print out the customer ID provided CustomerID is a public property/field.
2. <asp:ListBox ... datasource='<%# studentArray %>' ... /> this will bind the ListBox to an array of students.
3. Full Name: <%# (Student.FirstName + " " + Student.La   stName) %>
4. Number of users online: <%# GetUserCount() %>

The main idea here is that, the expression within the <%# %> is only executed when Page.DataBind() is called.

3- <%= %>
This works the same as the above expression syntax with the difference that this syntax is executed on page load without the need to call Page.DataBind(). Similar to Response.Write().

A very interesting method I came over today:

HttpResponse.ApplyAppPathModifier

According to the MSDN documentation:

Adds a session ID to the virtual path if the session is using Cookieless session state and returns the combined path. If Cookieless session state is not used, ApplyAppPathModifier returns the original virtual path.

This is very cute!! If you are using cookieless session state, you can easily you this method, give it a virtual path, it will automatically append the SessionId to the URL without any need to do any manual effort!!!

It is also helpful, when you want to redirect from Http to Https or vicaversa, it helps you maintain the same session Id when moving!

This is a small example:

Response.Write(Response.ApplyAppPathModifier("demo/default.aspx"));

will generate something as:

/App/(S(avsbnbml2n1n5mi5rmfqnu65))/demo/default.aspx

Hope this helps!

This is my last night I sleep here in my home in Beirut!! Tomorrow morning I am leaving outside the country following my company and going away from this ugly war we have that stopped everybody in Lebaon from going to their jobs, stopped them from their normal life they used to have!!!

I am leaving my beloved country and the pain is hitting every single part of my body, the pain of those families who lost their homes in thousands, the pain from what happened to my country, from the destruction we had here, from the hundreds of people who were killed and mainly children!!!

I am leaving my country and my heart is staying here, he is not accepting to leave his house, his country, his family, his friends, his beloved people!!!!!!

I will come back. Lebanon is for me, for every person who believes in Lebanon, we will build it again, no one would ever erase us from existence!!!!!

You can now debug an XSLT document in .NET 2.0.

You have now the XslCompiledTransform object that is used to do the transformation in .NET 2.0.

When you create your instance of the XslCompiledTransform use this constructor:

XslCompiledTransform xsl = new XslCompiledTranform(true);

Then, set a break point on the Tranform method call, when the debugger is there, hit F11 to enter the XSLT document and start debugging your Xslt file!
