I have a multcolumn combo box that is binded to a iList returned from OpenAccess.  This part is working great, however I need to only show certain columns in the drop down, not everyone.  With RadGridView I can do the following command that will stop it from auto creating the columns, then I am free to create the specific ones that I need:

table1.MasterGridViewTemplate.AutoGenerateColumns = false;

Is there an equivalent in this control?

Also, once you select a row, how do you obtain the value for say column 3?

Thanks, Ryan

Hi Ryan,

Thank you for your question.

Please refer to the following Help Article: RadMultiColumnComboBox - Overview. As you can read there, you need the EditorControl property which gives you the reference to the RadGridView in the dropdown.

Since the selection in RadMultiColumnComboBox is related to the CurrentRow of RadGridView, you can get a cell value by the CurrentRow property:

I hope this helps. If you have additional questions, feel free to contact me.

All the best,
