The difference is important, because these two technologies have radically different consequences for the design of your application. It s almost always safe to use the first level. It gives you all the flexibility you need to display your data with an elegant, extensible model. On the other hand, if you use both levels of data binding you need to be very cautious. You run the risk of creating applications where database code is tightly bound to individual forms in your application, and routines for common tasks like handling errors are scattered throughout your application. You also make it more difficult to change or optimize your approach data access. Figure 8-1 shows an example of the first approach an application that retrieves data objects by hand, but uses data binding to get the information into various controls for display. generate pdf thumbnail c#: C# Create PDF Thumbnail SDK: View, preview PDF thumbnail ... create thumbnail from pdf c# NuGet Gallery | Packages matching Thumbnail

iText and iTextSharp are PDF generators only unfortunately, and what you are looking for is actually PDF renderer. According to Bruno Lowagie the creator of ... Figure 8-1. Data binding in a .NET application In this example, a custom data access class (that you create) contains all the ADO.NET code. It contacts the database, performs a query, and transfers information into a data object (like the DataSet or a collection of objects). This data access class may be in the same assembly as the rest of your application, or for better componentization you can develop it in a separate class library project. Once the data object is returned, the information it contains is displayed in a form automatically, thanks to data binding. This automatic display works through various relationships between the data object and the controls on the form. These relationships are usually set up when the form is first created. Figure 8-2 shows how no-code data binding works in a Windows application. The ingredients that are involved are similar to those in Figure 8-1 namely, there s a class to retrieve data and a class to represent that data. However, there are two significant differences. By default, all the objects are contained by the form that displays the data. Unfortunately, this makes it difficult to bind the data to other forms without duplicating code. More importantly, to create the application in Figure 8-1, you need to code the data access class by hand and choose a suitable data object. But when you use the approach shown in Figure 8-2, the choice is out of your hands. The data access logic and the data object are generated automatically in Visual Studio, and your options for customizing it are limited. In this chapter, you ll start by exploring the first level (showing relational data in bound controls) and then consider whether or not it makes sense to use the second level (avoiding data access code altogether). c# split pdf itextsharp: How to convert "PDF TO IMAGE" in c# ? - C# Corner c# get thumbnail of pdf Generate Thumbnail Images from PDF Documents - Aspose.PDF for ...
