DataTable sheet1 = new DataTable("Excel Sheet");
OleDbConnectionStringBuilder csbuilder = new OleDbConnectionStringBuilder();
csbuilder.Provider = "Microsoft.ACE.OLEDB.12.0";
csbuilder.DataSource = filename;
csbuilder.Add("Extended Properties", "Excel 12.0 Xml;HDR=YES");
string selectSql = @"SELECT * FROM [Sheet1$]";

            using (OleDbConnection connection = new OleDbConnection(csbuilder.ConnectionString))


            using (OleDbDataAdapter adapter = new OleDbDataAdapter(selectSql, connection))
            {
                
                connection.Open();
                adapter.Fill(sheet1);

                connection.Close();

                
            }

Inherently, there's nothing in there that would cause the UI to resize. I assume, however, that there is a lot more to your code than this - what do you do with the DataTable? Is this being bound to something on the form?
