how to view all items in combobox when focus comes to combo

Basically with the help of two combobox events (enter & leave)  & one property (DroppedDown) you can achieve this.

 

 

private void comboBox1_Enter(object sender, EventArgs e)
{
      comboBox1.DroppedDown = true;
}


private void comboBox1_Leave(object sender, EventArgs e)
{
      comboBox1.DroppedDown = false;
} 

Hi Mahesh,

 

It is little bit confusing. 'View all items in combobox'- Currently all items are not visible? Can you please explain your issue more clearly.
