Check out the live demo of our ASP.NET Combo Box here: ASPxComboBox Multiple Columns

Screencast - Multiple Columns ListBox ComboBox

Check out the new multiple columns feature video which shows you how to display several columns inside of a list box or combo box.

The multiple columns feature is very slick. And it has the potential to replace the need for a grid.

Watch the video and learn:

  • How to setup an ASPxListBox for multiple columns
  • How to setup an ASPxComboBox for multiple columns
  • ASPxComboBox's (cool) TextFormatString property

All that in under 7 minutes! Click here to watch it now.

Done watching? Pretty nice, isn't it? Are you ready to use multiple columns now?

Wow, that's looking really great. I especially like the possibilities of the TextFormatString property!

Any examples in text i.e. not Video?

I am having  an error while trying to use the combo box inside a DetailsView control when the multi column feature is enabled. Setting the combo's property: Value='<%# Eval("SomeID") %>' seem to trigger the error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

The error goes away if i set DetailsView EnableViewState="False" or remove the multiple columns. Is this a bug?

Hi Mehul,

Thanks for making the video. I've implemented a multi column combo box column in a gridview. It works great, except I am not able to change the display format for columns in the combo box, especially when data types are

  boolean --- showed as True/False while users want Yes/No

  small money  -- scale showed four digits instead of two, e.g. 25.0000 instead of 25.00

The gridview is 9.2.6.0. Is there any way to control the format in this version or in a newer version?

Thanks.
