TableLayoutPanel的控制列属性

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

Go here .

This properties are added by means of "extending properties", something that other controls like ToolTip uses.

Answer 3

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.

Answer 4

// Create TableLayoutPanel TableLayoutPanel tlp = new TableLayoutPanel();

// Set the BorderStyle to Inset tlp.CellBorderStyle = TableLayoutPanelCellBorderStyle.Inset;

// Grid has two columns
tlp.ColumnCount = 2;

// Grid has two rows
tlp.RowCount = 2;

// If grid is full add extra cells by adding column
tlp.GrowStyle = TableLayoutPanelGrowStyle.AddColumns;

// Padding (pixels)within each cell (left, top, right, bottom)
tlp.Padding = new Padding(1, 1, 4, 5);

// Add TableLayoutPanel to the Forms controls
this.Controls.Add(tlp);
