Hi I just tried to select an item in alistview by code. But there is no SelectedIndex property, and also the property SelectedIndices does not provide a possibility. How do I do that?

Hello Gunter,

The ListView doesn’t have the SelectedIndex property (we should probably add it – it’s not in WinForms either) and the SelectedIndices and SelectedItems are read-only collections by design.

To select an item programmatically use the Selected property of the item: this.listView.Items[10].Selected = true. Look also at the SelectionMode and MultiSelect properties on the ListView. https://docs.wisej.com/api/wisej.web/lists-and-grids/listview

See https://msdn.microsoft.com/en-us/library/y4x56c0b(v=vs.110).aspx (you don need to set .Focused = true, use only .Selected = true)

HTH

Best,

Luca

    I don’t think there should be a SelectedIndex property since you may select more than one item.

    That’s probably why WinForms doesn’t have it. However, the ListBox has the SelectedIndex property and the option to have multiple selection. I’m not sure if the ListBox.SelectedIndex is -1 when there are multiple items or if it indicates the first – have to check.

Hi Luca

You’re right, but I am migrating a VWG application, and in VWG there ist a property SelectedIndex and so I thougt it’s the same in winforms.

Hi Luca

But setting listView.Items[xx].Selected = true does not properly get to work. Wenn I set listView.Items[xx].Selected = true, the value is set, SelectedItems is also properly updated, but the selection mark is never set. Please see the test application attached

Hi Frank

I just installed Version 1.3.5. When I set the selection by listView.Items[xx].Selected, on the selected item the background color is now properly set, but the orange border stays at the item recently selected by mouse click
