Infragistics系列控件怎么看皮肤控件加组合控件的混合体，用了2下就崩掉了！可能是盗版的原因吧！

通过DataGrid添加一个UserControl 的方式效果好像很不错，不过有滚动条时，定位就是个大问题，有什么解决方案没？

那就添加一个窗体, 专用于显示你需要的信息. 如何?

        private Form2 frm;

        private void button1_Click(object sender, EventArgs e)

        {

            DataTable dt = GetData();

            this.dataGridView1.DataSource = dt.DefaultView;

        }



        private DataTable GetData()

        {

            DataTable dtData = new DataTable();

                using (SqlConnection thisConnection = new SqlConnection(

                   @"Data Source=HUI\SQLSERVER;Initial Catalog=Northwind;Integrated Security=True"))

                {

                    using (SqlDataAdapter thisAdapter = new SqlDataAdapter(

                        "SELECT * FROM Customers", thisConnection))

                    {

                        thisAdapter.Fill(dtData);

                    }

                    thisConnection.Close();

                }

            return dtData;

        }



        private void Form1_Load(object sender, EventArgs e)

        {

            frm = new Form2();

            frm.TopLevel = false;

            frm.FormBorderStyle = FormBorderStyle.None;

            this.dataGridView1.Controls.Add(frm);

            frm.Hide();

        }

        

        private void dataGridView1_CurrentCellChanged(object sender, EventArgs e)

        {

            if (this.dataGridView1.CurrentCell==null)

                return;



            Rectangle rect = this.dataGridView1.GetCellDisplayRectangle(dataGridView1.CurrentCell.ColumnIndex + 1,

                dataGridView1.CurrentCell.RowIndex + 1, false);



            frm.Location = new Point(rect.Left - 50, rect.Top - 10);

            frm.Size = new Size(200, 200);

            frm.BackColor = Color.Yellow;

            //此处可对frm进行初始化值

            frm.Show();

        }



        private void dataGridView1_Leave(object sender, EventArgs e)

        {

            frm.Hide();

        }
