What is "sql image" and what does "do not work" mean?

If I understand your question then what you are asking is this:

You have an image in your program.
You want the image shown in a Tooltip.
You want that shown when you mouse over an entry in the datagrid.

You are displaying a very small snippet of what looks like XAML to me. Is this a WPF application, a Silverlight application, or just a web page?

this is a wpf application. I saved a picture in sql databse, and i can retrieve and see it in datagrid but i want to do mouse over on picture, tooltip display it more larger (zoom).

I saved a picture in sql databse, and i can retrieve and see it in datagrid but i want to do mouse over on picture, tooltip display it more larger (zoom).
This code block has this message in tooltip:Byte[] Array.

XML

<DataGridTemplateColumn Header="Image" Width="45" >
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate >
                            <Image Source="{Binding Path=Picture}" Width="100" Height="50" Stretch="Uniform"  ToolTip="{Binding Path=Picture}">                           
                            </Image>
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>

Add new record event:

C#

private void btnAdd_Click(object sender, RoutedEventArgs e)
        {
            
                Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
                dlg.Filter = "Image Files(*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|All files (*.*)|*.* ";

                dlg.ShowDialog();

                FileStream fs = new FileStream(dlg.FileName, FileMode.Open, FileAccess.Read);
                byte[] data = new byte[fs.Length];

                fs.Read(data, 0, System.Convert.ToInt32(fs.Length));
                fs.Close();

                System.IO.Stream stream = System.IO.File.Open(dlg.FileName, System.IO.FileMode.Open);

                BitmapImage imgsrc = new BitmapImage();
                imgsrc.BeginInit();
                imgsrc.StreamSource = stream;
                imgsrc.EndInit();
                this.Picture.Source = imgsrc;

                SqlConnection con = new SqlConnection();
                con.ConnectionString = @"Data Source=.\SQLEXPRESS;AttachDbFilename=E:\programing\WPF\DataBase.mdf;Integrated Security=True;User Instance=True";
                con.Open();

                SqlCommand sc = new SqlCommand("Insert Into Personnels(No,Name,Family,Picture) Values(@No,@Name,@Family,@Tozihat,@Picture)", con);

                sc.Parameters.AddWithValue("@No", txtNo.Text);
                sc.Parameters.AddWithValue("@Name", txtName.Text);
                sc.Parameters.AddWithValue("@Family", txtFamily.Text);
                sc.Parameters.AddWithValue("@Picture", data);

                sc.ExecuteNonQuery();
                con.Close();

}
