unable to handle null values in ComboBox ?

Feb 21 2013 3:51 AM
Hie friends

Well i used a button and combo box . when i click on button it should display what ever i selected in combo box :) when i select something in comboBox its working fine but when i un-intentionally click on button without selecting anything in comboBox ITS THROWING me Null Reference Exception :(

How to handle this ? Is there any other way except exceptional handling ?

My Code :
private void button1_Click(object sender, EventArgs e)


private void button1_Click(object sender, EventArgs e)
foreach(object obj in ComboBox1.SelectedItem.ToString())


Foreach also failed to handle null but its not used here in this context :D
Thank you in advance
