Function "IndexFromPoint"

[lupotana]

Hi,
in normal Listbox there's a function called IndexFromPointi.
This function received the position of mouse cursor (X and Y) and return the index of listbox

This function is not present in RadListBox ?

Thanks,
Marco Bianchi

Hello Marco,

Thank you for the suggestion for such an API. Your points have been updated for that.
Until we add the API, you can use the method given below:

private int IndexFromPoint(RadListBox listBox, Point pos)
{
    RadItem item = listBox.ElementTree.GetElementAtPoint(pos) as RadItem;
    if (item != null)
        return listBox.Items.IndexOf(item);
    return -1;
}

For example, the code in the handler for MouseMove event of RadListBox will be:

private void radListBox1_MouseMove(object sender, MouseEventArgs e)
{
    int indexUnderMouse = IndexFromPoint((RadListBox)sender, e.Location);
}

If you have further questions, do not hesitate to write us.
