Just wondering if there is a way to easily lookup the rows and columns currently in a FlowLayoutPanel or if a manual calculation is required?

A manual calculation is required.

This thread is old yet I had the requirement just today and GetFlowBreak was failing to return true on a control that caused the flow panel to break onto a new line. I am not sure why and I didn't have time to figure it out. This works for FlowDirection = LeftToRight.

Frankly, I don't have time to write this but I am anyway. Here is a simple extension method that will calculate the number of rows:

    public static int GetRowCount(this FlowLayoutPanel flowPanel)
    {
        int rows = 1;

        int rowWidth = flowPanel.ClientRectangle.Width;

        foreach (Control control in flowPanel.Controls)
        {
            rowWidth -= control.Width;

            if (rowWidth > 0)
            {
                continue;
            }

            rows += 1;
            rowWidth = flowPanel.ClientRectangle.Width;
        }

        return rows;
    }

Use:

    int rows = ChoiceFlow.GetRowCount();

HTH!
