TableLayoutPanel Control Overview
The TableLayoutPanel control arranges its contents in a grid. Because the layout is performed both at design time and run time, it can change dynamically as the application environment changes. This gives the controls in the panel the ability to proportionally resize, so they can respond to changes such as the parent control resizing or text length changing due to localization.
Any Windows Forms control can be a child of the TableLayoutPanel control, including other instances of TableLayoutPanel. This allows you to construct sophisticated layouts that adapt to changes at run time.
The TableLayoutPanel control can expand to accommodate new controls when they are added, depending on the value of the RowCount, ColumnCount, and GrowStyle properties. Setting either the RowCount or ColumnCount property to a value of 0 specifies that the TableLayoutPanel will be unbound in the corresponding direction.
You can also control the direction of expansion (horizontal or vertical) after the TableLayoutPanel control is full of child controls. By default, the TableLayoutPanel control expands downward by adding rows.
If you want rows and columns that behave differently from the default behavior, you can control the properties of rows and columns by using the RowStyles and ColumnStyles properties. You can set the properties of rows or columns individually.
The TableLayoutPanel control adds the following properties to its child controls: Cell, Column, Row, ColumnSpan, and RowSpan.
You can merge cells in the TableLayoutPanel control by setting the ColumnSpan or RowSpan properties on a child control.
