This would explain why
int col = lesson.GetPositionFromControl((Control)sender).Column; returns -1
(though I'm not sure if (Control)sender is correct, it appears to be
though).
The code I've used for inserting the columns is this
public lessonplan(int noperiods)
{
float periodSize = 100.0F / (float)noperiods;
InitializeComponent();
this.lesson.ColumnCount = noperiods + 1;
this.lesson.ColumnStyles.Add(new
System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Absolute,
120F));
for (int i = 0; i < noperiods; ++i)
{
this.periodlabel[i] = new
System.Windows.Forms.Label();
this.lesson.ColumnStyles.Add(new
System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent,
periodSize));
this.periodlabel[i].Location = new
System.Drawing.Point(127 + (117 * i),
2);
this.periodlabel[i].Text = "Lesson " + (i +
1).ToString();
this.periodlabel[i].AutoSize = true;
this.periodlabel[i].Font = new
System.Drawing.Font("Arial", 18F,
System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point,
((byte)(0)));
this.periodlabel[i].Size = new
System.Drawing.Size(109, 27);
this.periodlabel[i].TabIndex = i + 6;
this.lesson.Controls.Add(this.periodlabel[i], i
+ 1, 0);
}
Invalidate();
}
This is called when the table is clicked, so it's being set up after the
window is initially set up.
Does this mean that I'm relying on the TLP or something else (which would
also explain the -1)?
TTFN
