Datagridview cellvalidating cancel

06-Jul-2017 03:11

1) Add a conditional statement in the event handler code to only execute when required.

2) Detach the event hander before the unwanted event triggers and re-attach after.

So my question is how can I have both validation and the ability to cancel edit of the datagridview row?

I don't mind if the current row in the datagridview is lost when edit is canceled.

定义单元格验证要求:验证错误后焦点不离开。实现:单元格的验证可以使用dgv_details_Cell Validating事件。验证不通过时调用e.

Send("^a");将全选单元格的内容。 单元格选中并开始编辑状态实现://Data Grid View获得焦点dgv_details.

I've tried a few things and have searched for answers without luck so far.Microsoft is conducting an online survey to understand your opinion of the Msdn Web site.If you choose to participate, the online survey will be presented to you when you leave the Msdn Web site. Hi there, I have a question regarding datagridview, I add data to the datagridview in an interface and all the validation for the datagridview cell is in the datagridview cell validating event for the datagridview.

I display the data of the is datagridview in another interface and make the cells read-only. But the thing is when I click on a row that data was added previously and press the Add new row the cell validating event is triggered.

You can also build this example in Visual Studio by pasting the code into a new project.
