If the returned value is NULL, bind a new DataTable object
DataView.DataSource = new Datatable ()
DataView.Databind ();
Or put the data source. Clear ();
Because the null value is the Count of the data source is not, not 0, is not
When you Clear (), the Count property value of the object becomes 0, then the binding will also display the table header

<asp: gridview ....>
<emptydatatemplate>
<asp: label ...>
There is no data to show in this view.
</ asp: label>
</ emptydatatemplate>
</ asp: gridview>

The above code adds an emptydatatemplate template,
Prompt message is displayed when the data source is empty, the template is ignored if it is not empty

When the data source record is zero, the data source is empty!

I also have a problem like yours, but it seems there is no way. Finally, the attributes are added:
EmptyDataText="<div align=center><font color=red>There is no data you need</font></div>"

Adding an empty record to the bound datatable is ok
