disable the controls in panel

Makes more sense now..

You will need to do the following steps-

1. Create a dictionary object with
2. when you're looping to create buttons, store each button in the dictionary with value false.
3. whenever user selects a button inside the panel, modify the corresponding button value in dictionary from false to True.
4. On proceed button, when you recreate the panel and buttons using loop, check the status of button in the dictionary. If the status is false, then btn.Enabled=false else btn.Enabled=true.

Hope this helps!

i can explain in a detailed way....
assume that we need to develop a project for booking tickets for a movie theater.and we are generating the seats buttons of the theater using for loop.and when the user clicks on the buttons .the respective buttons must be selected...and when the user clicks on proceed button.the selected buttons must be stored in list item and depending up on the list content the buttons in the panel will be in disable state.

Share some code and graphics of ur form :)

not like that my dear,in the form we have two types of buttons
1.buttons which are  in panel
2.proceed button on form(not in panel) for submitting form
      if we click on submit button the selected buttons in panel control will go into disable state..

1. On button click, get the reference of the button that was clicked.
2. Disable the panel
2. Enable the clicked button.

protected void btn_Click(object sender, EventArgs e)
{
        Button b = (Button)sender;
        if(b!=null)
        {
                pnl.Enabled=false;
                b.Enabled=true;
        }
}

disabling the panel itself will disable all controls inside the panel.
