How to select row in FastObjectListView?

I really lost heart in tries how to select row in the FastObjectListView (C#, Windows Forms).

I have object and index of this object in the grid, but i can't make it selected! All i've made - move scroll to this row, but not select it.

Methods:

idx = index of row with my object
obj = my object

gvRaces.Items[idx].Selected = true;
gvRaces.SelectObject(obj , true);
gvRaces.SelectedItem = (OLVListItem)gvRaces.Items.Find(obj.Id.ToString(), true).FirstOrDefault(); -

for last method i have a question. What is a key in method ...Items.Find(key, searchAllSubitems)?

all of this methods change properties in my fastObjectListView, but don't change any items visually.

How to select my row?

Solution

  • You already have the right answer:

    gvRaces.SelectObject(obj , true);

    This would also work (and is probably more what you want):

    gvRaces.SelectedObject = obj;

    Rev1.0's point is still valid -- make sure that obj is actually an object in the control. The control uses Equals() to decide if two objects are equal.

    Also, ensure that olv.HideSelection is false. This is a very annoying MS provided property that turns off selection when the ListView doesn't have focus. It makes it look as if SelectObject() hasn't worked when it actually has.
