Prevent FlowLayoutPanel scrolling to updated Control

I have an application which uses a FlowLayoutPanel with a lot of Custom UserControls in it. The Custom UserControls contains a Label.

The problem: When the Label is updated the FlowLayoutPanel automatically scrolls it into view (Similar to the FlowLayoutPanel.ScrollControlIntoView() function).

This is the code snippet that makes the FlowLayoutPanel Scroll:

private void DownloadChanged(Object sender, DownloadProgressChangedEventArgs e)
{
        progressDownload.Value = e.ProgressPercentage;
        lblDownloaded.Text = e.BytesReceived.ToString() + " / " + e.TotalBytesToReceive.ToString();
}

I have been trying to find an event in the FlowLayoutPanel which I can intercept and stop it from scrolling when a child updates but I have not had any luck so far.

Is it possible to do this? If yes, how would I go about it? Thanks!

If having scrolling issues when clicking on a control in a FlowlayoutPanel, use an inherited control:

public class MyFlowLayoutPanel : FlowLayoutPanel
{

    protected override System.Drawing.Point ScrollToControl(Control activeControl)
    {
        //return base.ScrollToControl(activeControl);
        return this.AutoScrollPosition;
    }
}

Setting the the Label's AutoSize Property to False seems to do the trick.
