Devexpress GridControl数据验证的方法

向GridView里增加两个事件

private void gdvStruct_ValidatingEditor(object sender, BaseContainerValidateEditorEventArgs e)
{
ColumnView view = sender as ColumnView;
GridColumn column = (e as EditFormValidateEditorEventArgs)?.Column ?? view.FocusedColumn;
if (column.FieldName != "StructName") return;
string value = e.Value.ToString();
e.Valid = Regex.IsMatch(value, @"^[u4E00-u9FA5a-zA-Z0-9_.]+$");
}

private void gdvStruct_InvalidValueException(object sender, InvalidValueExceptionEventArgs e)
{
ColumnView view = sender as ColumnView;
if (view == null) return;
e.ExceptionMode = ExceptionMode.DisplayError;
e.WindowCaption = "格式错误";
e.ErrorText = "只允许英文字母、数字、汉字和.";
view.HideEditor();
}
