column

The column position of the control to retrieve.

The child control occupying the specified cell; otherwise, a null reference (Nothing in Visual Basic) if no control exists at the specified column and row, or if the control has its Visible property set to false.

Exception typeCondition

ArgumentException

Either column or row (or both) is less than 0.

The column and row position values are zero based.

The following code example enumerates all the cell positions in the TableLayoutPanel by looping through the columns and rows given by ColumnCount and RowCount, and then calling the GetControlFromPosition method to retrieve the control at each cell.

private void getcontrolFromPosBtn_Click(
    System.Object sender, 
    System.EventArgs e)
{
    int i = 0;
    int j = 0;
    Trace.WriteLine(this.TableLayoutPanel1.ColumnCount);
    Trace.WriteLine(this.TableLayoutPanel1.RowCount);

    for(i=0; i<=this.TableLayoutPanel1.ColumnCount; i++)
    {
        for(j=0; j<=this.TableLayoutPanel1.RowCount; j++)
        {
            Control c = this.TableLayoutPanel1.GetControlFromPosition(i, j);

            if( c != null )
            {
                Trace.WriteLine(c.ToString());
            }
        }
    }
}
