Hi Rhea,

Thank you for your question.

To select an item programmatically, you can set the SelectedItem property of RadListView. Alternatively, you can use the Select(ListViewDataItem[] items) method:

//to select a single item:
this.radListView1.SelectedItem = this.radListView1.Items[0];
//to select multiple items when multiselect is enabled:
this.radListView1.Select(new ListViewDataItem[] { this.radListView1.Items[0], this.radListView1.Items[1] });

I hope this will help you. Feel free to write back if you have any further questions.

All the best,

Good Day, 

I want to allow the item selection, but with only one click ( on click event, ) let the multiselection ( if I had CTRL key pressed ).
Is there some property for use selection with one click and simulate CTRL press?

Thanks a lot.
Oscar

Hi Oscar,

Thank you for writing.

Currently, this functionality is not supported in RadListView. However it can be achieved by using the ItemMouseDown and ItemMouseUp events. For example you can store the selected items in the ItemMouseDown and restore them in ItemMouseUp event handler:

List<ListViewDataItem> selected = null;

void radListView1_ItemMouseDown(object sender, ListViewItemMouseEventArgs e)
{
    selected = radListView1.SelectedItems.ToList();

    if (!selected.Contains(e.Item))
    {
        selected.Add(e.Item);
    }
    else
    {
        selected.Remove(e.Item);
    }
}

void radListView1_ItemMouseUp(object sender, ListViewItemMouseEventArgs e)
{

    radListView1.SelectedItems.Clear();
    radListView1.Select(selected.ToArray());
}
