具有数据绑定的DataGridView中的奇怪复选框行为

[英]Odd checkbox behavior in DataGridView with databinding

原文 2011-06-24 10:48:52 9 1 .net/ datagridview

I am using databinding to bind List with my datagridview. 我正在使用数据绑定将List与我的datagridview绑定。

MyItem class contains checkbox element and displays correctly in datagridview. MyItem类包含复选框元素，并在datagridview中正确显示。 But the selection behavior is odd. 但是选择行为很奇怪。 When I select the check box the same field in MyItem does not update. 当我选中复选框时，MyItem中的相同字段不会更新。

When I change selected row(focus on checkedbox lost) the same field in corresponding instance of MyItem class is updated. 当我更改选定的行（失去选中框时）时，将更新MyItem类的相应实例中的相同字段。

If I understand you correctly, what you are describing is the standard behaviour for all DataGridView cell types - the cell value changed event (and the databinding) occurs when focus leaves the cell. 如果我理解正确，那么您所描述的是所有DataGridView单元格类型的标准行为-当焦点离开单元格时，发生单元格值更改事件（和数据绑定）。

As they say in the article I linked to, and as you allude to in your question, for a checkbox this behaviour is often not ideal. 正如他们在我所链接的文章中所说，以及您在问题中提到的那样，对于此复选框，此行为通常不理想。 To work around this you can handle the CurrentCellDirtyStateChanged and call the CommitEdit method. 要解决此问题，您可以处理CurrentCellDirtyStateChanged并调用CommitEdit方法。 There is some discussion and example code here . 有一些讨论和示例代码在这里。
