In the implementation of this event, we would have to go through all the rows that have any info on them and perform the validation required, setting the appropiate error messages in the cell. Data Grid View控件 Data Grid View是用于Windows Froms 2.0的新网格控件。它可以取代先前版本中Data Grid控件，它易于使用并高度可定制，支持很多我们的用户需要的特性。 关于本文档： 本文档不准备面面俱到地介绍Data Grid View，而是着眼于深入地介绍一些技术点的高级特性。 本文档按逻辑分为5个章节，首先是结构和特性的概览，其次是内置的列/单元格类型的介绍，再次是数据操作相关的内容，然后是主要特性的综述，最后是最佳实践。 大部分章节含有一个“Q & A”部分，来回答该章节相关的一些常见问题。注意，某些问题会由于知识点的关联性重复出现在多个章节。这些问题、答案及其附带的示例代码都包含在本文档的附录部分。 内容 1 何为Data Grid View.. Excluding rows is useful to avoid a performance penalty when you are working with a large quantity of rows.So again I ask, does anyone know the order of events that happen when a row is updated/added to a Data Grid View.I am talking about all the events, not just the row or cell events.I need to find out the order of events that are fired when a Row is updated in a Data Grid View control. | MSDN Data Walkthroughs VBForums Database Development FAQ My Code Bank Submissions: VB | C# My Blog: Data Among Multiple Forms (3 parts) Beginner Tutorials: VB | C# | SQL Gee thanks..I have looked just about everywhere and cannot find this simple information. there is just one problem, there are other things that happen as well, such as cellenter, cellleave, then of course all of the rowvalidating/ed, and cellvalidating/ed events that happen.whichever you are looking for (pre/post changed value).If so, at the table level, after the data is queried and populated for the grid population, you could then...
So if anyone of the super master programmers (jmcilhinney not included) here have an answer to this, at least for me, VERY URGENT question, please!!! I realize you know quite a bit, but that was a little degrading.
On the other hand, if the user is required to enter data in all the rows and the validation is simple; the first approach is convenient.
In order to implement Immediate validation, the event Cell Validation must be handled Ex The validation to check if the cell is in edit mode is very important. For the Late Validation, there must be an event that is perform once the user finish entering data.
It is also useful to provide initial sizes for user-resizable rows, columns, and headers, and for column fill mode.
Programmatic resizing is useful to avoid performance penalties with continuous resizing.
