I have this sidespace in the grid dedicated to show the expansion buttons:
But I can't find any style setting(even in override) that let me change that backcolor.
If there's any, where I can find this style setting?
Hello Eugenio,
Thank you for contacting Infragistics. Based on your image, it appears you want to style the GroupByRowConnector.
If your grid is not grouped, please provide a larger image and some setup code demonstrating your view.
Yes, this is the component of interest but I discovered that it's overriden by DisplayLayout.Appearance.BackColor because otherwise it doesn't update the BackColor setup at GroupByRowConnector, thanks anyway for the support.
If you could send us a small isolated sample I would take a look at it. Thanks.
