The Point that represents the upper-left corner of the control relative to the upper-left corner of its container.

Examples

The following code example creates a GroupBox and sets some of its common properties. The example creates a TextBox and sets its Location within the group box. Next, it sets the Text property of the group box, and docks the group box to the top of the form. Lastly, it disables the group box by setting the Enabled property to false, which causes all controls contained within the group box to be disabled.

   // Add a GroupBox to a form and set some of its common properties.
private:
   void AddMyGroupBox()
   {
      // Create a GroupBox and add a TextBox to it.
      GroupBox^ groupBox1 = gcnew GroupBox;
      TextBox^ textBox1 = gcnew TextBox;
      textBox1->Location = Point(15,15);
      groupBox1->Controls->Add( textBox1 );

      // Set the Text and Dock properties of the GroupBox.
      groupBox1->Text = "MyGroupBox";
      groupBox1->Dock = DockStyle::Top;

      // Disable the GroupBox (which disables all its child controls)
      groupBox1->Enabled = false;

      // Add the Groupbox to the form.
      this->Controls->Add( groupBox1 );
   }

// Add a GroupBox to a form and set some of its common properties.
private void AddMyGroupBox()
{
   // Create a GroupBox and add a TextBox to it.
   GroupBox groupBox1 = new GroupBox();
   TextBox textBox1 = new TextBox();
   textBox1.Location = new Point(15, 15);
   groupBox1.Controls.Add(textBox1);

   // Set the Text and Dock properties of the GroupBox.
   groupBox1.Text = "MyGroupBox";
   groupBox1.Dock = DockStyle.Top;

   // Disable the GroupBox (which disables all its child controls)
   groupBox1.Enabled = false;

   // Add the Groupbox to the form.
   this.Controls.Add(groupBox1);
}

' Add a GroupBox to a form and set some of its common properties.
Private Sub AddMyGroupBox()
   ' Create a GroupBox and add a TextBox to it.
   Dim groupBox1 As New GroupBox()
   Dim textBox1 As New TextBox()
   textBox1.Location = New Point(15, 15)
   groupBox1.Controls.Add(textBox1)
   
   ' Set the Text and Dock properties of the GroupBox.
   groupBox1.Text = "MyGroupBox"
   groupBox1.Dock = DockStyle.Top
   
   ' Disable the GroupBox (which disables all its child controls)
   groupBox1.Enabled = False
   
   ' Add the Groupbox to the form.
   Me.Controls.Add(groupBox1)
End Sub

Remarks

Because the Point class is a value type (Structure in Visual Basic, struct in Visual C#), it is returned by value, meaning accessing the property returns a copy of the upper-left point of the control. So, adjusting the X or Y properties of the Point returned from this property will not affect the Left, Right, Top, or Bottom property values of the control. To adjust these properties set each property value individually, or set the Location property with a new Point.

If the Control is a Form, the Location property value represents the upper-left corner of the Form in screen coordinates.
