推荐答案

在此处放置一些代码-也许有人可以为您提供帮助.

Put some code here - someone may be able to help you then.

默认情况下，数据网格已与数据表/数据集绑定.因此，如果没有记录从数据库返回，则您的数据表中不存在任何行，因此没有任何内容显示为gridvew的一部分.这是datagrid的工作原理.

现在，如果要显示标题:
在将数据表与gridview绑定之前，请检查行数.如果该值为零，则从您的侧面显式添加一行，并说空有效值.现在，将此新更新的数据表绑定到gridview.您可以看到带有标题的gridview.

您甚至可以根据需要在行的单元格中添加一些文本-类似于未找到记录"(这将需要编写进一步的代码，例如删除单元格中的控件并添加文本)

By default the datagrid is binded with the datatable/dataset. Thus if no record is returned from the database, your datatable has no rows present and thus nothing is displayed as a part of the gridvew. This is something as datagrid works.

Now, if you want to display header:
Before binding the the datatable with the gridview - check the row count. If that is zero then add a row explicitly from your side with lets say empty valid values. Now bind this new updated datatable to the gridview. You can see the gridview with headers.

you can even add a some text to the cells of the row if needed -something like ''No Records found'' (this will need further code to be written like removing the controls in the cells and adding a text)
