Combobox format displays tab in textbox, not in dropdown [duplicate]

Question

This question already has an answer here:

how to put a newline/tab in a combobox [duplicate] (1 answer)

Closed 9 years ago.

I have a Province object, with ProvinceCode and ProvinceName properties. I want to display both in a Visual Webgui (Winforms-based) combobox, with a tab between them.

I am using the PropertyChanged - Format event, as suggested by Eliran's answer to this question:

    private void Province_Format(object sender, ListControlConvertEventArgs e)
    {
        string provCode = ((Province)e.ListItem).ProvinceCode;
        string provName = ((Province)e.ListItem).ProvinceName;
        e.Value = provCode + "\t" + provName;
    }

When the combobox is rendered, the tab displays properly in the textbox area, but displays as a single space in the listbox area.

Does a Winforms combobox support tabs in its listbox area?

Simplest way to achieve this, if your goal is strictly text spacing for display, is to just define and use your own "tab":

public const string TEXT_TAB = "    ";

private void Province_Format(object sender, ListControlConvertEventArgs e)
{
    string provCode = ((Province)e.ListItem).ProvinceCode;
    string provName = ((Province)e.ListItem).ProvinceName;
    e.Value = provCode + TEXT_TAB + provName;
}
