Practical .NET

Preloading Your ASP.NET Applications

If you're using the ASP.NET Cache object, then somebody is suffering when you first load the Cache. Here's how to avoid that and, potentially, save a bit of money while you're at it.

Cool New Features in ASP.NET 4

Peter starts looking at the new features in ASP.NET 4, starting with support for compressing Session data and setting up permanent redirects.

A Modest Proposal on Validation in the Middle Tier

Peter looks at a strategic issue: When to do validation? The answer isn't "Everywhere" but it could have been.

The QueryExtender

Extend runtime sorting and filtering of data with ASP.NET 4's QueryExtender, which provides a single interface for DataSources.

Inserting with jQuery

Peter Vogel continues to extend his client-side case study by using jTemplate to extend a table to support inserts -- and then sending the user's data to the server to update the database.

Deleting with jQuery and Web Services

Peter continues to extend his jQuery/jTemplate case study by supporting deletes of multiple rows with a single mouse click.

Updating From the Client with jQuery

Peter continues to exploit jQuery in his client-side code to integrate an ASP.NET page with a WCF service -- this time to support updating data.

Defining Templates with jTemplate

A combination of client-side code, WCF services, and jQuery lets you retrieve data from your sever and display it to the user using Web Services and client-side code.

Building Better Client Internet Apps

Peter looks at the options for client-side development and the practicalities of leveraging ASP.NET.

Suppressing the Back Button: Just Say No

Peter deals with all the people who want to disable the Back button. First, he tells them to stop asking but (finally) breaks down and suggests a solution.

Maintaining Data Integrity from the DataView

DataViews fire a range of events that you can use to ensure that data is correct before it goes to the database -- and they're especially useful when you're using the GridView or DetailsView.

Dynamically Setting Parameters

At design time, you can tie parameters in the DataSource to a variety of data sources. But sometimes the source for your values can't be set at design time. Here's how to set those values at runtime.

Dynamic Data Retrieval

You can't always make all of your data retrieval decisions at design time -- sometimes you have to wait for the user to tell you what data to get. Peter shows you how to work with a DataSource to retrieve data dynamically at runtime.

Getting Files To and From the Server

The FileUpload control and the ASP.NET Response object let you move files between the browser and the server. And moving in each direction just requires a few lines of code.

Dynamically Generate Complex Pages with the MultiView

The MultiView control allows you to swap sets of controls on and off the page. But the MultiView control also makes it easier for you to generate new page content and add it at run time.
