TableLayoutPanel's Control Columns properties

Question

I've noticed that every control added to the TableLayoutPanel is given "Column" and "Row" properties. How can I get access to these properties through code?
thanks:)

Answer 1

These properties only exist in the Properties Window, magic provided by the IExtenderProvider interface. They don't exist at runtime. Extended properties are:

• ColumnSpan. Runtime: GetColumnSpan() and SetColumnSpan()
• RowSpan. Runtime: GetRowSpan() and SetRowSpan()
• Row. Runtime: GetRow() and SetRow()
• Cell. Runtime: GetCellPosition() and SetCellPosition()
• Column. Runtime: GetColumn() and SetColumn()

Obviously TLP was highly optimized to be used from the designer. It's kinda of a pain at runtime.

Answer 2

Although the properties designer shows the row and column as properties of the added control thay are set programatically using a method on the table layout panel itself (SetColumn(control, index) and SetRow(control, index)).

This pattern of behaviour is similar the tool tip component and the error component.
