Hello Ayberk,

There is no client property that indicates which elements are selected in the ListView. But you can easily transfer the selected items from server-side to client-side using a hidden field for example.

C#:

protected void RadListView1_PreRender(object sender, EventArgs e)
{
    string selectedIndexes = "";

    if (RadListView1.SelectedIndexes.Count > 0)
        selectedIndexes = RadListView1.SelectedIndexes[0].ToString();
    for (int i = 1; i < RadListView1.SelectedIndexes.Count; i++)
    {
        selectedIndexes += ";" + RadListView1.SelectedIndexes[i];
    }
    RadListView1SelectedIndexes.Value = selectedIndexes;
}

JavaScript:

var selectedIndexes = ($get("RadListView1SelectedIndexes").value).split(';') ;
