I want to change the
backcolor of a listViewDataItem, then later on, change it back to the standard
color (ie white if it's not selected or the standard selection color of it's
selected).

I'm using this code to change the backcolor:

previewedListItem.BackColor = Color.Gold
previewedListItem.BackColor2 = Color.Gold
previewedListItem.BackColor3 = Color.Gold
previewedListItem.BackColor4 = Color.Gold

and this code to change it back:

previewedListItem.BackColor = Color.FromArgb(0, 0, 0, 0)
previewedListItem.BackColor2 = Color.FromArgb(0, 0, 0, 0)
previewedListItem.BackColor3 = Color.FromArgb(0, 0, 0, 0)
previewedListItem.BackColor4 = Color.FromArgb(0, 0, 0, 0)

The problem is that once I've changed it back, if the user selects that item,
it stays white instead of showing the selection color. How can I change the
color back in a way that will still show the selection color if the item is
selected?

Also, I've seen the article about using the VisualItemFormatting event to change the backcolor. Using this approach, I'm not sure how to work out which item I should be changing the backcolor of. I would like to check the value of one of the items in the listviewdataitem.databounditem and change the backcolor depending on the value. How do I get to the databound item in the VisaItemFormatting event?

Hi Simon,

Thank you for writing.

To reset a setting introduced in a formatting event, you need to use the ResetValue method and reset the locally introduced settings:
e.VisualItem.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);

And here is how to access the data bound value:
e.VisualItem.Data.DataBoundItem

I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.

Regards,
