TableLayoutPanel content control stretching

Question

using System.Drawing; using System.Windows.Forms; public class Test { Form form; GroupBox groupBox; TableLayoutPanel tableLayoutPanel; Label label; TextBox textBox; Button button; public Test() { this.form = new Form(); this.form.Text = "Test"; this.form.MinimumSize = new Size(600, 300); this.groupBox = new GroupBox(); this.groupBox.Text = "Input"; this.groupBox.Dock = DockStyle.Fill; this.tableLayoutPanel = new TableLayoutPanel(); this.tableLayoutPanel.Dock = DockStyle.Fill; this.tableLayoutPanel.ColumnCount = 3; this.tableLayoutPanel.RowCount = 1; this.tableLayoutPanel.CellBorderStyle = TableLayoutPanelCellBorderStyle.Single; this.label = new Label(); this.label.Text = "Input file:"; this.label.Anchor = (AnchorStyles) (AnchorStyles.Top | AnchorStyles.Left); this.textBox = new TextBox(); this.textBox.Text = "Test"; this.textBox.Anchor = (AnchorStyles) (AnchorStyles.Left | AnchorStyles.Top | AnchorStyles.Right); this.textBox.Dock = DockStyle.Fill; this.button = new Button(); this.button.Text = "Browse..."; this.button.Anchor = (AnchorStyles) (AnchorStyles.Top | AnchorStyles.Right); this.tableLayoutPanel.Controls.Add(this.label, 0, 0); this.tableLayoutPanel.Controls.Add(this.textBox, 1, 0); this.tableLayoutPanel.Controls.Add(this.button, 2, 0); this.groupBox.Controls.Add(this.tableLayoutPanel); this.form.Controls.Add(this.groupBox); this.form.ShowDialog(); } public static void Main() { new Test(); } } /* When compiling this, the textbox does not appear, I'm assuming because of the Anchoring and the column it's within can't AutoSize.. Anyway, if you switch the order of addition to the tableLayoutPanel between the button and textBox, e.g.: this.tableLayoutPanel.Controls.Add(this.label, 0, 0); this.tableLayoutPanel.Controls.Add(this.textBox, 2, 0); this.tableLayoutPanel.Controls.Add(this.button, 1, 0); The textBox appears, and stretches when resizing. *** This is the desired effect however with the textBox situated in the middle row ***. The only solution I've come up with so far is the following: this.tableLayoutPanel.ColumnStyles.Add(new ColumnStyle(SizeType.Absolute, this.label.Width)); this.tableLayoutPanel.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 100)); this.tableLayoutPanel.ColumnStyles.Add(new ColumnStyle(SizeType.Absolute, this.button.Width)); Which doesn't seem too nice and causes some delay on Windows while resizing as it tries to update and gets caught up in some presumed resize calculation loop for a second or two with the desktop Icons and the application itself flickering away. */
