Datagrid视图异常DataError事件 [英] Datagrid view exception DataError event

问题描述

Hi Folks，

当我更改datagrid视图单元格值并删除一些主键值时。有一个弹出窗口显示要替换此默认对话框，请处理dataError事件。。我不知道我应该在哪里处理这个错误。找不到在代码中放置try catch的地方。

请建议我在哪里放置try catch来处理数据网格视图上的这种异常

问候

Hi Folks,
When I change the datagrid view cell value and delete some primary key value. there is a popup that says "To replace this default dialog please handle the dataError Event.". I am not sure where should I handle this error. find no place to put try catch in the code.
Please suggest where should I place the try catch to handle such an exception on datagrid view
Regards

推荐答案

void InitializeComponent() {
   // ... //

   this.DataGridView.DataError += this.DataGridView_DataError;
}

void DataGridView_DataError(object sender, DataGridViewDataErrorEventArgs e) {
   e.ThrowException = false;
}

使用此代码你将捕获错误，然后根据该错误执行。

Use this code u will capture the error then perform according to that error.

你能给我发一个代码块来理解这个问题吗？

can you send me the code block to understand the issue?
