Search Records From Textbox And Display In DataGridView

I want to get an input from the textbox, and display the records into the datagridview, But is it possible If no records, the datagridview shows only empty cells?

This is the code to display records.
con1.Open()
sqlsearch = "SELECT * FROM setting WHERE mname LIKE'%" &
TextBox1.Text & "%'"
Dim adapter As New OleDbDataAdapter(sqlsearch, con1)
Dim dt As New DataTable("setting")
adapter.Fill(dt)
Form2.DataGridView1.DataSource = dt
con1.Close()
RefreshDGV()
