Sure.

If you notice the code of how GridView is populated, you will find that you get a dataset/datatable and assign that as a datasource to grid. After which you call a Databind method of it.

Internally, data is binded and Rowdatabound is called that many number of times as much number of rows returned in the datatable. This in return shows you those rows.

Now, at your page load or any given scenario, if the datatable assigned to the grid is having ZERO rows in it then there would be no binding and thus no display of grid or headers etc.

In order to handle this scenario such that you still see headers of grid or some label in it, you need to write a little extra code from your side. Steps:
1. Before assigning the datasource to grid, check for number of rows in the table
2. If it's more than zero then go with normal flow
3. If it's zero then create a dummy table from your side, add a dummy row with no values or some text in it
4. Assign this new table to grid and call databind method.

Done! Try.
