Datagridview rowvalidating e cancel

Interaction with the Data Grid View often requires that you programmatically discover which cell is currently active. You can perform these tasks with the Current Cell property.

All Cells; Auto Size Columns Mode 属性的设定值枚举请参照 msdn 的 Data Grid View Auto Size Rows Mode 说明。 2)指定列或行自动调整 // 第一列自动调整 Data Grid View1. Auto Size Mode =Data Grid View Auto Size Column Mode. 后,有意义的。有关自定义排序信息,请参见本主题中的自定义排序节后面。 当Data Grid View控件同时包含绑定和未绑定列进行排序,在未绑定列的值不能自动维护。为了保持这些值,你必须执行Virtual Mode属性设置为true,并处理Cell Value Needed和Cell Value Pushed事件虚拟模式。 5.6.1编程排序 您可以排序的Data Grid View编程方式调用它的排序方法。 本的Sort(Data Grid View Column,List Sort Direction)Sort方法重载采用Data Grid View Column和一个枚举值作为参数List Sort Direction。此重载时非常有用,可以通过与有意义的命令,但你不想配置值的列自动分拣排序。当调用此重载并同一个Data Grid View Column Sort Mode.

When you programmatically resize columns that have Inherited Auto Size Mode property values of Fill, however, the calculated content-based widths are used to proportionally adjust the column Fill Weight property values, and the actually column widths are then calculated according to these new proportions so that all columns fill the available display area of the control.

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.

I'm trying to do something like this: If New Record Row entered then Do something Else Do something else End If I assume that code such as the above could be put in the Data Grid View_Selection Changed event and it would execute whenever the user navigated to a dirrerent row. highlighted, which can occur without the Current Row changing.

Current Cell Changed also gets raised when changing cells within the same row.
