HI,

I have code like this,
ComboBox1.SelectedIndex = 0

and I am getting error below
Value of '0' is not valid for 'SelectedIndex'

How do I set the default value of combobox? (first item in the list)

Can I use the code below? what happnes if combobox doesn't have any values?
ComboBox1.SelectedIndex = ComboBox1.Items.Item(0).ToString

Thanks

Using ToString() will definitly NOT work (it will not compile) since the SelectedIndex property is of type int whereas ToString() returns a string.
You get this exception because the number of Items in your combo is 0 (no items at all) and therefore you cannot select the first item (there is no first item).
