    When using the standard listbox control i use the IndexFromPoint Method to get the item at the point of the mouse click...
    like...

    private void listBox1_MouseDown(object sender, MouseEventArgs e)
    {
        int index = listBox1.IndexFromPoint(e.Location);
        listBox1.SelectedIndex = index;
    }
    is a there a way to do such with a RadListControl?

    Hello Andy,

    Thank you for writing and for the provided code snippet.

    To achieve the same functionality using the RadListControl, you should use the following code:

    private void radListControl1_MouseDown(object sender, MouseEventArgs e)
    {
      RadElement element = this.radListControl1.ElementTree.GetElementAtPoint(e.Location);
     
      if (!(element is RadListVisualItem))
      {
        element = element.FindAncestor<RadListVisualItem>();
      }
     
      if (element != null)
      {
        RadListDataItem item = ((RadListVisualItem)element).Data;
        this.radListControl1.SelectedItem = item;
      }
    }

    I hope you will find this useful. Please note that we are still expecting an answer from your on the questions asked in your thread: "unable to clear multiple selected dates". This will allow us to continue supporting your enquiries.
