How to draw inference from MySQL DB in Data Grid VB?

Question

MySQL

Goodnight. I'm trying to display the database in a DataGrid (I have 4 columns), but it starts throwing an error:
: "Could not cast object type 'System.Data.DataTable' to type 'System.Collections.IEnumerable'.""

Dim sqlConn As New MySqlConnection
    Dim sqlCmd As New MySqlCommand
    Dim sqlData As New DataTable

Private Sub updateTable()

        Dim DataSuspects As New DataGrid


        sqlConn.ConnectionString = "server =" + server + ";" + "user id=" + username + ";" + "password= " + password + ";" + "database =" + database

        Dim query As String
        query = "SELECT * FROM `suspects_arrests`"
        Dim sqlAdap As New MySqlDataAdapter(query, sqlConn)
        sqlAdap.Fill(sqlData)
        DataSuspects.ItemsSource = sqlData

    End Sub

What am I doing wrong?
