Using ComboBox in Infragistics Ultragrid

Aaron Young — Sat, 12 Apr 2008 17:09:51 GMT

Hi,

I would like to add a dropdown list to a column in an Ultragrid. I tried to use a SF ComboBox control as the EditorControl for the column. However, the following error is thrown when the application runs:-

"EditorControl property can only be set to a control that implements IProvidesEmbeddableEditor interface."

As the ComboBox doesn't implement this interface, how do you add dropdown lists to a column in an Ultragrid? Which control do you use?

Thanks,

Aaron

I tried subclassing the combobox and implementing the interface but there are problems with that as the control is expected to expose several features, e.g. Editor, etc.

I will use the Infragistics combo instead. It probaby suits us as we already have a subclassed grid that will automatically create the dropdowns based on tag values. i doubt it will take much to convert this to create and populate a BO instead.

Thanks.

You would have to use an Infragistics combo, not a standard SF combo. You should be able to use the Infragistics Wrapper combo as this inherits from the UltraCombo which should have than implementation. If not, then it would be a matter of creating a custom class and just implementing that interface:

[codesnippet]Public Class MyEmbeddableCombo
Inherits MicroFour.StrataFrame.UI.WIndows.Forms.ComboBox
Implements IProvidesEmbeddableEditor

End Class[/codesnippet]

In any case, you should be able to get it accomplished without too much effort.
