Solution 1

Couple of things... are you populating your checked listbox first? If so, remember that your index is zero based, ie: it goes from 0 to n-1 where n is the number of items in your list.

Also, there's no need for you to set the value of selectedIndex1 to CheckedListBox1.SelectedIndex, as you are immediately changing it to 1 on the next line.

Change the value of your selected index to 0 since that the first index would be zero. Do it like this so that you wouldn't have exceptions.

if(CheckedListBox1.Items.Count != 0)
{
   selectedIndex = 0;
   //wherein 0 is apple.
}

Solution 2

Use this code in your form load event handler

VB

CheckedListBox1.SetItemChecked(0, True)

0 = "Apple"
1 = "Cow"
2= "Milk"
etc....
