DataGridView in WPF

Question

 

Hello , I want to make a DataGridView with the server data. It does not work and I think that is when >>> dgvPerfil.DataContext = dtPre1 ; <<< Below is the code in the method, the DataGridView is called dgvPerfil , and he will receive the connection string when the method is called . What am I missing ? Thank you all for your help.

 

 

 

public void ListPerfil(String verrdgda)

{

ConectionClass coneli = new ConectionClass();

cone.connect();

SqlCommand cverrdgda = new SqlCommand(verrdgda, cone.con);

try

{

SqlDataAdapter objsql1 = new SqlDataAdapter(cverrdgda);

DataTable dtPre1 = new DataTable();

objsql1.Fill(dtPre1);

dgvPerfil.DataContext = dtPre1;

}

catch

{

MessageBox.Show("Connecting to the server unavailable!", "Error");

cone.disconnect();

}

finally

{

coneli.desconectar();

}

}
