As well as all of the HTML controls (and their server-side variants), ASP .NET offers another set of controls for the use of web form programmers. These are the web server controls (or just web controls, since they re always server controls), and they re located in the Web Forms tab of the Toolbox. Many of these controls have direct HTML equivalents, but there are several new ones, too. Of the many reasons for choosing web server controls over HTML controls, here are the most important ones: Web server controls offer a layer of abstraction on top of HTML controls. At runtime, some of them comprise a number of HTML elements, and therefore offer greater functionality with less design-time code. In a moment, we ll look at an example featuring the Calendar control, which demonstrates this idea quite nicely. Since web controls are independent of the markup that will render them at runtime, some of them will render different HTML depending on the browser they re being viewed with, to improve compatibility. An example is the Panel control, which renders as a <div> on Internet Explorer, but as a <table> on Netscape browsers. Web server controls have a more consistent and logical object model than HTML elements, with some properties common to all web controls (including style-related properties such as BackColor, BorderColor, Font, and so on). vb.net code 39 reader VB .

We create and populate a table with one row per date over a five-year date range (see script date_oddity.sql in the online code suite). birt data matrix, birt code 128, birt code 39, birt report barcode font, ms word code 39, birt ean 13 vb.net code 39 reader read code 39 barcode with vb . net - Stack Overflow

If the space you reserve for your text fields is not sufficient, the text content is truncated so that it fits into the available area. This scenario is not always acceptable, so you can let the reporting engine calculate the amount of space required to display the entire content of the text field at runtime, and automatically adjust the size of the report element. To do this, set isStretchWithOverflow to true for the particular text field elements you are interested in.
