Visually i have 10 rows on the screen
If i query the tableLayoutPanel.rowcount is always equals 2
this coincidentally equal my initial design time rows
i basically want to cycle through each control in the first column and need to know the number of rows

RowCount and ColumnCount don't return the number of items

You can specify both the ColumnCount and the RowCount properties for layouts with a known and fixed number of cells. You can also specify one property or the other if you expect the number of cells in your layout to grow, assuming that the GrowStyle property allows for such growth. If the value of RowCount is 0, the panel will grow by adding rows, and if the value of ColumnCount is 0, the panel will grow by adding columns. Specifying panel growth with the GrowStyle property is preferred to setting RowCount or ColumnCount to 0, however.

if you want the number of rows returned
you need to use the SQL command rowcount

USE AdventureWorks;
GO
SELECT count(*) AS Count
FROM Production.ProductInventory
WHERE Quantity < 300;
GO
