How to set constraints in WinForm? - winforms

Question

I created UserControl and put there a two GroupBox one at the top and one at the bottom... there is a screenshot
And then when I put this UserControl with my a views within to TabController I got such a result
So, as you see in the main form it looks like it is not enough space for all views within UserControl
Question is - is there a way to set that GroupBox at the top will take 50% of the height and GroupBox at the bottom will take also 50% of the height, such way this two GroupBox view will take 100% of the height each for 50%...

Answer 1

alternatively use TableLayoutPanel with two rows (each row gets 50% height)
private void InitializeComponent()
{
this.tableLayoutPanel1 = new System.Windows.Forms.TableLayoutPanel();
this.groupBox1 = new System.Windows.Forms.GroupBox();
this.groupBox2 = new System.Windows.Forms.GroupBox();
this.tableLayoutPanel1.SuspendLayout();
this.SuspendLayout();
//
// tableLayoutPanel1
//
this.tableLayoutPanel1.ColumnCount = 1;
this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 100F));
this.tableLayoutPanel1.Controls.Add(this.groupBox1, 0, 0);
this.tableLayoutPanel1.Controls.Add(this.groupBox2, 0, 2);
this.tableLayoutPanel1.Dock = System.Windows.Forms.DockStyle.Fill;
this.tableLayoutPanel1.Location = new System.Drawing.Point(3, 3);
this.tableLayoutPanel1.Name = "tableLayoutPanel1";
this.tableLayoutPanel1.RowCount = 3;
this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 50F));
this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Absolute, 4F));
this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 50F));
this.tableLayoutPanel1.Size = new System.Drawing.Size(507, 408);
this.tableLayoutPanel1.TabIndex = 0;
//
// groupBox1
//
this.groupBox1.Dock = System.Windows.Forms.DockStyle.Fill;
this.groupBox1.Location = new System.Drawing.Point(3, 3);
this.groupBox1.Name = "groupBox1";
this.groupBox1.Size = new System.Drawing.Size(501, 196);
this.groupBox1.TabIndex = 0;
this.groupBox1.TabStop = false;
this.groupBox1.Text = "groupBox1";
//
// groupBox2
//
this.groupBox2.Dock = System.Windows.Forms.DockStyle.Fill;
this.groupBox2.Location = new System.Drawing.Point(3, 209);
this.groupBox2.Name = "groupBox2";
this.groupBox2.Size = new System.Drawing.Size(501, 196);
this.groupBox2.TabIndex = 1;
this.groupBox2.TabStop = false;
this.groupBox2.Text = "groupBox2";
//
// Form3
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(513, 414);
this.Controls.Add(this.tableLayoutPanel1);
this.Name = "Form3";
this.Padding = new System.Windows.Forms.Padding(3);
this.Text = "Form3";
this.tableLayoutPanel1.ResumeLayout(false);
this.ResumeLayout(false);
}
#endregion

private System.Windows.Forms.GroupBox groupBox2;

Answer 2

you can use SplitContainer (IsSplitterFixed = true; will not allow to change proportions)
private void InitializeComponent()
{
this.splitContainer1 = new System.Windows.Forms.SplitContainer();
this.groupBox1 = new System.Windows.Forms.GroupBox();
this.groupBox2 = new System.Windows.Forms.GroupBox();
((System.ComponentModel.ISupportInitialize)(this.splitContainer1)).BeginInit();
this.splitContainer1.Panel1.SuspendLayout();
this.splitContainer1.Panel2.SuspendLayout();
this.splitContainer1.SuspendLayout();
this.SuspendLayout();
//
// splitContainer1
//
this.splitContainer1.Dock = System.Windows.Forms.DockStyle.Fill;
this.splitContainer1.IsSplitterFixed = true;
this.splitContainer1.Location = new System.Drawing.Point(3, 3);
this.splitContainer1.Name = "splitContainer1";
this.splitContainer1.Orientation = System.Windows.Forms.Orientation.Horizontal;
//
// splitContainer1.Panel1
//
this.splitContainer1.Panel1.Controls.Add(this.groupBox1);
//
// splitContainer1.Panel2
//
this.splitContainer1.Panel2.Controls.Add(this.groupBox2);
this.splitContainer1.Size = new System.Drawing.Size(459, 395);
this.splitContainer1.SplitterDistance = 197;
this.splitContainer1.SplitterWidth = 1;
this.splitContainer1.TabIndex = 0;
//
// groupBox1
//
this.groupBox1.Dock = System.Windows.Forms.DockStyle.Fill;
this.groupBox1.Location = new System.Drawing.Point(0, 0);
this.groupBox1.Name = "groupBox1";
this.groupBox1.Size = new System.Drawing.Size(459, 197);
this.groupBox1.TabIndex = 0;
this.groupBox1.TabStop = false;
this.groupBox1.Text = "groupBox1";
//
// groupBox2
//
this.groupBox2.Dock = System.Windows.Forms.DockStyle.Fill;
this.groupBox2.Location = new System.Drawing.Point(0, 0);
this.groupBox2.Name = "groupBox2";
this.groupBox2.Size = new System.Drawing.Size(459, 197);
this.groupBox2.TabIndex = 0;
this.groupBox2.TabStop = false;
this.groupBox2.Text = "groupBox2";
//
// Form2
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(465, 401);
this.Controls.Add(this.splitContainer1);
this.Name = "Form2";
this.Padding = new System.Windows.Forms.Padding(3);
this.Text = "Form2";
this.splitContainer1.Panel1.ResumeLayout(false);
this.splitContainer1.Panel2.ResumeLayout(false);
((System.ComponentModel.ISupportInitialize)(this.splitContainer1)).EndInit();
this.splitContainer1.ResumeLayout(false);
this.ResumeLayout(false);
