Hi C1,
it seems the RibbonComboBox in the new “C1.Ribbon” namespace does not support “IFormatProvider”, as the System.Windows.Forms.ComboBox properties “FormattingEnabled”, “FormatString” and “FormatInfo” do.
I noticed this when I tried to migrate a combobox on a RibbonControlHost to a RibbonComboBox.
Would be nice if this could be added. For now, I will stay with a RibbonControlHost.
Best regards
Wolfgang

Hi Wolfgang,
The development team has asked if you could provide more information on this.
The RibbonComboBox doesn’t support data binding,
MS Combobox uses formatting to display data (int, DateTime, etc.) of items, how do you want to use the formatting for the RibbonCombobox?

Hi,
attached is a sample which shows the expected behavior for a WinForms ComboBox: the combobox data is a custom class, and I want to control the displayed text (instead of using “ToString” of the custom class). So I use an “IFormatProvider” implementation.
Would be nice if the RibbonComboBox supported a similar approach.
But this would probably mean major changes, as the “RibbonButton” constructor only accepts text and no data of type “object”.
Best regards
Wolfgang
