sagar55, can I ask why anyone would ever need a multicolumn combobox?

Why not just format the text in a single column combobox in a way that allows it to appear as its multicolumn?

Solution 1

1. Create the Control. You may inherit ComboBox, UserControl, Control, Form or NativeWindow.
2. Add it too your Form. You may either select it from the toolbox, or add the logic in your Form's constructor.

Solution 2

If you're new to C#, you should learn to use the controls that exist before you consider writing your own control.

Solution 4

Assuming this an extenal dll the easiest way is:

Right click on the ToolBox and 'Choose Items'.
'Browse', find the dll and click OK.
Now you can drag and drop it from the ToolBox like any other control and your project references will be updated automatically.

A combo box does not do what he wants, therefore this answer is wrong.
