Introduction to asp.net
This document provides an introduction to ASP.NET development. It outlines that ASP.NET is a server-side language that uses a simplified page development model and modular, extensible architecture. It also discusses ASP.NET features like superior debugging, rich caching support, scalable session state, and error recovery. The document then covers request and response processing, common technologies used like HTML and JavaScript, and how ASP.NET web forms separate code from design and use server controls like Windows forms. It explains the ASP.NET page lifecycle and concepts like postbacks and view state. It concludes by discussing using session state and application state to store object data and how to start ASP.NET development using web sites versus web applications.
Introduction to asp.net
- 2. Asp.NET ? Simply Server side language Simplified page development model Modular, well-factored, extensible architecture Superior debugging and tracing support Compiled, not interpreted Rich caching support Web farm scalable session state Automatically detects and recovers from errors
- 4. General Things to know ClientSide Scripting Server Side Scripting HTML JavaScript CSS JQuery Ajax XML
- 5. Web Forms in .NET Separate Code & Design Rich Web Forms Drag & Drop Design Like WinForms
- 6. Understand the Web Form Page Directive Server side code Form Normal HTML Structure Server Controls
- 7. Page Life Cycle Init PreInit Init PreLoad Complete Pre Load Control Load Render Complete events Save Render Unload StateComplete
- 8. You must Know PostBack communicates back to the server View State state stored in a hidden field on the page transported to the client and back to the server, Is not stored on the server
- 9. ASP.NET States Session State allows the state of objects (serializable) to be stored for a single session (lifetime of the user’s browser or specific timeout) Application State allows the state of objects (serializable) to be stored for the application across different sessions.
- 10. Master Page Template to Other pages
- 11. Starting ASP.NET Development Web Site Don’t use this, here for compatibility only Each page is dynamically loaded into memory Slow on first load after deployment No need to recompile for code change
- 12. Starting ASP.NET Development .. Web Application Recommended Compiles all pages into one DLL Faster on first load after deployment Must recompile whole site for code change
- 13. Thank You!
