You don't.
What you do is create your own event in Form2 - call it "ShowData" - which Form1 handles.
You signal the event, Form1 handles it, closes the Form2 instance, and takes the appropriate action - i.e. it calls the same method as it's DataShow button even handler does.

That sounds complicated, but it really isn't - it's how the whole of .NET works, pretty much!
Have a look here: Transferring information between two forms, Part 2: Child to Parent[^] it includes the code you need to modify.

Solution 2

Just add code after the ShowDialog call to call the DataShow method.

C#

DialogResult dr = searchform.ShowDialog()
if (dr == DialogResult.OK)
{
    DataShow();
}
else
{
// process other response(s)
}
