How do I get a MultColumnComboBox to auto drop down when a user starts typing in the control?

Hi Jerry,

You can handle the KeyPress event and set the

DroppedDown property to true as shown below.

private void multiColumnComboBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
if(e.Handled ==false)
this.multiColumnComboBox1.DroppedDown =true;
this.multiColumnComboBox1.DroppedDown =false;

Please take a look at the sample attached and let us know if you have any difficulties.

That works. It causes the dropdown to flash/jump on each keypress.

I tried putting DroppedDown = true in the Enter event - the dropdown doesn''t appear.

Is there a way to get around the flashing of the dropdown?

Hi Jerry,

Thanks for your reply. I could see the issue and this can be ignored by introducing a small condition in the same code. Please take a look at the sample attached.
