Possible Bug of the TableLayoutPanel?

Try this to duplicate the possible bug:

1. Drag a tablelayoutpanel on a form inside the VS 2005IDE.
2. Make it two rows and two columns.
3. Put a textbox in the seond column on the seond row
4.Setthe textbox'scolumnspan = 2.

Since the default growbehavior of the tablelayoutpanel is to add rows, our textbox will now move to the newly-added row to occupy two columns. Everything is fine, right? But wait, we cannot drag our textbox toanywhere any more. No matter how hard you try, the textbox will stay in the newly-added row. This behavior seems not right to me. Is this by design? Could you please check this out, Martin?

Anyone can confirm this, or just me?

Thanks,

The problem seems caused by the follwing insertion of rowstyles. When a new row was added, only a new row style was added, makie the total rowstyles to 3. Whilethe total row count still the same as before adding a new row, that's 2.

this.tableLayoutPanel1.RowCount = 2; //Still two rows!!!!

this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Absolute, 74F));

this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Absolute, 22F));

this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Absolute, 20F)); //A new rowstyle was added.

My problem is hosting this tableLayoutPanel on the custom designer. Seems I cannot hook up the on controladded event to change the rowcount. How should I approach this issue, please kindly advise.

Thanks for your time and expertise.
