Such a lot net functions stick to an easy "3F" trend: fetch, layout, and ahead to the browser. With this in-depth consultant, you will take your ASP.NET and ADO.NET abilities to the subsequent point and examine key ideas to boost extra advanced net functions. realize the way to construct functions for advert hoc and potent internet reporting, purposes that paintings disconnected from the information resource and use XML to speak with non-Microsoft.NET platforms, and common objective purposes that make the most of the information abstraction of ADO.NET. alongside the best way, you are going to easy methods to benefit from code reusability, consumer controls, code-behind, customized net controls, and different time-saving thoughts hired through ASP.NET specialists.

NET object can now be safely stored in a Session slot. This overcomes the thread-affinity problem you might have experienced with ASP and Visual Basic COM components. Second, the Session object is the programming interface for a moduleâ the Session Managerâ that can work in-process and out-of-process, and can even rely on SQL Server for data storage. This is probably the best reason to opt for Session: it now works well with Web farm architectures. NET applications will take advantage of the Cache object for all of their caching needs.
Instead of serializing each column, you could store only the information that you need to re-create the column. aspx, I persist a string made of comma-separated numbers, each of which identifies a particular column. aspx application is available on the companion CD. Figure 2-5 shows the dynamically displayed columns. Figure 2-5 Columns bound programmatically are persisted across multiple page requests. ViewState vs. Attributes 30 31 ViewState is a global, page-scoped repository of persistent information.
For now, suffice to say that you have to figure out the best way to track the data source on the server any time processing is required, and you must provide the logic to carry out the desired tasksâ paging, sorting, filtering, and so on. NET classes help you implement a lot of these tasks, they donâ t automatically handle them all. For this reason, I like to refer to the pagination feature of DataGrid controls as semi-automatic built-in features. Semi-Automatic Pagination Before I discuss any further the programming details of pagination, let me spend some time explaining the overall programming interface of the DataGrid control so that you can understand the rationale behind some apparently odd design choices.
