Edit in multi-columns comboBox

[Administratif]

How Can I allow edit in a multi-columns comboBox ?

I have a list in this combo with two columns (checkBoxColumn and textColumn). The user can check witch column he want's to select. 

The propriety ReadOnly of the comboBox is set as False;

I found the solution : this.cboListeErreur.EditorControl.ReadOnly = false;

But, there is a problem. When I click on a checkBoxColumn, the popup close it self directly !

The popup must be open while the combobox as the focus.

Hello Samuel,

Thank you for writing.

You can use the DropDownClosing event of the control to cancel the popop closing when you need.

I hope this helps. Let me know if you need anything else.
