Getting the message: "back call without drill through report" when pressing the backspace button

Question

I have about 20 local reports on a report viewer inside a winform. They all load fine/take parameters etc. But whenever I press the backspace button the report disappears and I am presented with this message: Back call without drillthrough report.

I am not using any drillthrough reports or sub reports and I haven't implemented anything to do with the backspace button in my code. (I'm using VB)

Is there a way to stop this from happening?

Answer 1

I had this same issue as well. I do not have any subreports or drillthroughs configured. I was able to capture the backspace and handle it there. The keydown event handler below belongs to the form and not to the reportviewer control itself. I'm on VS2010.

private void rptViewer_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Back)
        {
            e.Handled = true;
        }
    }
