点击DataGridView报错，提示框：DataGridView Default Error Dialog

The following exception occurred in the DataGridView
system.IndexOutOFrangeException: Index 54 does not have a value
at System.Windows.Forms.CurrencyManager.get_Item(Int32 index)
at System.Windows.Forms.DataGridView.DataGridViewDataConnection.GetError(Int32 rowIndex)
To replace this default dialog please handle the DataError event

网上找了半天没有可行的方法

这个一般是由于datagridview绑定了数据源，但是输入的内容与数据源的格式不一致引起的
可以在DataError的事件里面写判断

很难重现郁闷啊
