I did a search and usually, the answers are only shown text. do I have to convert class to string? and how do i apply it to PictureBox? the PictureBox have an image so I want to apply lowpass filter to the image in PictureBox using Combobox

Answer 1

You can do this a couple different ways

the first one would be without databinding

MSDN Add/Remove items to dropdown WF

Just call

comboBox1.Items.Add("Low Pass"); 
comboBox1.Items.Add("High Pass");

on the onload MSDN event in windows forms

then on the selectedindex change event you handle what to do when one or the other is selected

you can do this by checking combobox1.text

if (combobox1.text == "High Pass")
{
  //apply filter
}
else if (combobox1.text == "High Pass")
{
  //apply filter
}

Something else you can look into is databinding MSDN
