How to get the Cell Position of a TableLayoutPanel for a radioButton

Question

Here is my code, it is returning (-1, -1) as the coordinates of the cell position. Which I assume means the control was not found in the table. My radio buttons are sitting inside a panel within the table cell. However, radio.Container returns null.

private void radio_CheckedChanged(object sender, EventArgs e)
{
    var radio = sender as RadioButton;
    var coord = tblPanel.GetPositionFromControl(radio);//returns (-1, -1)
}

I would like to get the row number from the sender object by any means necessary. Thanks for any help you can provide.

Answer 1

Turns out what I needed was the parent property which in this case was the panel. Container was always null.

private void radio_CheckedChanged(object sender, EventArgs e)
{
        var radio = sender as RadioButton;
        var row = tblPanel.GetRow(radio.Parent);
}
