Question

我在尝试Print the File和Print Preview the File时遇到此错误：

enter image description here

这是我要打印的DataGridView Database上的文件，我从Checkboxes手动添加Access Database，其值为Yes or No Database：

enter image description here

当Print the file不是Print Preview the file但是Columns时，我正在使用此Checkboxes代码和Textboxes代码，并且它完美无缺。< / p>

只有当我想Print the file使用下面的代码时，我在之前的系统上使用了Checkboxes时，这段代码会给我一个错误（如上图所示）：

以下是代码，如果下面的代码太长，我很抱歉：
