C# DataGridView Check if empty

Question

I have a datagridview which gets filled with data returned from a linq query. If the query returns no results I want to display a messagebox. Is there a way of checking to see if the datagridview is empty?

Regards

Answer 1

You can know if it' empty by checking the number of rows in the DataGridView. If myDataGridView.Rows.Count == 0 then your DataGridView is empty.

Answer 2

You can check the Rows.Count property of the datagridview.

Although you might also want to look into the EmptyDataText property of the DataGridView. It might save you showing a messagebox.

Answer 3

Based on the Linq results, you can hide the datagridview and show some other control (like a Literal or something) that shows the message. If you want some sort of messagebox popup, you'd need to throw some JavaScript in there.
