Two different kinds of events are red when the user modi es the contents of an input TextField, Event.CHANGE and TextEvent.TEXT_INPUT. There are three main differences between these events. First, the TextEvent.TEXT_INPUT event is red when the user types text in the eld, whether that changes the contents of the eld or not. For example, typing illegal characters inside a restricted input eld doesn t change the text because these characters are ignored. However, the TEXT_INPUT event is red. This also means that when the user deletes text with the backspace key or the clipboard, the TEXT_INPUT event is not red. The Event.CHANGE event, on the other hand, is dispatched only when the actual contents have changed, and it doesn t care if that s from typing, deleting, cutting, or pasting. Second, the TEXT_INPUT event is red before the contents of the eld change, whereas the CHANGE event is red after the contents have changed. So when you look at the text property of a TextField while it dispatches a TEXT_INPUT event, it contains the text in that eld immediately prior to the event occurring. During a CHANGE event, the text property is already up-to-date. pdf editor in c# PDF - XChange Tutorials

Finally, the TEXT_INPUT event tells you what text is about to be added. You can nd this in the text property of the TextEvent. Because it happens before the text is actually added, and it tells you what text is about to be added, you can cancel the event with preventDefault() to prevent the user s text addition from taking place. In other words, by listening to the TEXT_INPUT event, you can gain much ner or context-sensitive control over what goes into a TextField when a user types into it. This could be used to automatically add dashes to license keys or automatically capitalize letters as you type them. If you just want to know when the contents of the TextField have changed, however, Event.CHANGE is a much simpler event to listen to. You can use this to do on-the- y validation of form elds. Example 17-9 adds a Submit button to the form you built in Examples 17-7 and 17-8 and only lets the user click this button when all the elds are correct. birt gs1 128, birt ean 13, birt barcode, word pdf 417, birt upc-a, qr code generator for word free c# edit pdf ITextSharp edit an existing pdf - Stack Overflow

For example, you might need to add a column or row in the middle of several existing columns or rows to add data that you left out the first time you created the workbook. With Excel, you can add columns and rows using the Insert button on the Ribbon or using the Insert dialog box. You are not limited to inserting new columns and rows one at a time; if you want, you can insert multiple new columns and rows at once.
