DataGridView.CellValidating 事件的问题
我调协了这个事件,我是用手去邦定数据
邦定数据的时候就报错了,好像就在执行这个事件
不知道怎么解决?
private void dataGridView1_CellValidating(object sender,
DataGridViewCellValidatingEventArgs e)
{
dataGridView1.Rows[e.RowIndex].ErrorText = " ";
int newInteger;
// Don 't try to validate the 'new row ' until finished
// editing since there
// is not any point in validating its initial value.
if (dataGridView1.Rows[e.RowIndex].IsNewRow) { return; }
if (!int.TryParse(e.FormattedValue.ToString(),
out newInteger) || newInteger < 0)
{
e.Cancel = true;
dataGridView1.Rows[e.RowIndex].ErrorText = "the value must be a non-negative integer ";
}
}
------解决方案--------------------使用CellValidated呢?
------解决方案--------------------细看:不可能啊!出什么错?

我手动绑定不会出错!
