  To display a dropdown in GridView take a look at sample code in docs:

  http://msdn2.microsoft.com/en-us/library/system.windows.forms.datagridviewcomboboxcolumn(VS.80).aspx

  Here's a list of various column types supported by GridView:

  You need to add Timer component (available under Components in ToolBox). To update your time display every second, set timer's interval to 1000. Interval is measured in milliseconds. Set Enabled property to true, and finally handle its Tick event, and call the code you mentioned above. Here's sample of how to use Timer:

  namespace log_in

  {

  public partial class login_form : Form

  {

  public login_form()

  {

  InitializeComponent();

  }

  private void InitializeTimer()

  {

  //' Run this procedure in an appropriate event.

  // Set to 1 second.

  timer1.Interval = 1000;

  // Enable timer.

  timer1.Enabled = true;

  }

  private void timer1_Tick(object sender, EventArgs e)

  {

  label7.Text = DateTime.Now.ToString();

  }

  when i run this code it's displays in the form "label7"

  I believe you are referring to GridView when you mentioned DataGrid. If "better way" mean displaying dropdowns, checkboxes etc then it is possible. Please give us a specific scenario to help you with a code sample.

  To clear items in the listbox you can use: yourListBoxName.Items.Clear() method.

  You have written a method to initialize the timer InitializeTimer() but did not call it anywhere. After InitializeComponents() type in following code:

  if (!DesignMode)
  InitializeTimer();
