In WinForm, I have a ComboBox. I am trying to do something like this.

When ComboBox has only 1 item, that item should be set as "Selected Text" for ComboBox, and when it has items more than 1, first item should be set as "Selected Text".

I want this to be happened at the time of Form Load.

how can i do this?

If I understand it the right way, you want the first item of the combobox to be selected/shown in comboBox.

This is quite easy:

comboBox1.SelectedIndex = 0; //This will select the first item in the combobox (zero based numbering)

To set it right after the form is shown simply put it after

InitializeComponent();

of the appropriate form.
