Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Remarks
The ScrollableControl.DockPaddingEdges class creates a margin on a given edge or all edges of a docked control. You can set the width of this margin for each individual edge by setting the following properties: Bottom, Top, Left, Right. Alternatively, you can set all the edges to the same width simultaneously by setting the All property. If the size of the control is too large for its container, the control will be resized to fit in the container, minus the specified margin width.
Example
[Visual Basic, C#, C++] The following example uses the derived class, Panel. The example docks a button in a panel control and cycles through the ScrollableControl.DockPaddingEdges properties, setting each individually on the click of the button. This code assumes a Panel control and a Button have been instantiated on a form, and a class-level member variable named myCounter has been declared as a 32-bit signed integer. This code should be called on the Click event of the button.
[Visual Basic] Private Sub SetDockPadding() ' Dock the button in the panel. button1.Dock = System.Windows.Forms.DockStyle.Fill ' Reset the counter if it is greater than 5. If myCounter > 5 Then myCounter = 0 End If ' Set the appropriate DockPadding and display ' which one was set on the button face. Select Case myCounter Case 0 panel1.DockPadding.All = 0 button1.Text = "Start" Case 1 panel1.DockPadding.Top = 10 button1.Text = "Top" Case 2 panel1.DockPadding.Bottom = 10 button1.Text = "Bottom" Case 3 panel1.DockPadding.Left = 10 button1.Text = "Left" Case 4 panel1.DockPadding.Right = 10 button1.Text = "Right" Case 5 panel1.DockPadding.All = 20 button1.Text = "All" End Select ' Increment the counter. myCounter += 1 End Sub [C#] private void SetDockPadding() { // Dock the button in the panel. button1.Dock = System.Windows.Forms.DockStyle.Fill; // Reset the counter if it is greater than 5. if (myCounter > 5) { myCounter = 0; } /* Set the appropriate DockPadding and display which one was set on the button face. */ switch (myCounter) { case 0: panel1.DockPadding.All = 0; button1.Text = "Start"; break; case 1: panel1.DockPadding.Top = 10; button1.Text = "Top"; break; case 2: panel1.DockPadding.Bottom = 10; button1.Text = "Bottom"; break; case 3: panel1.DockPadding.Left = 10; button1.Text = "Left"; break; case 4: panel1.DockPadding.Right = 10; button1.Text = "Right"; break; case 5: panel1.DockPadding.All = 20; button1.Text = "All"; break; } // Increment the counter. myCounter += 1; } [C++] private: void SetDockPadding() { // Dock the button in the panel. button1->Dock = System::Windows::Forms::DockStyle::Fill; // Reset the counter if it is greater than 5. if (myCounter > 5) { myCounter = 0; } /* Set the appropriate DockPadding and display which one was set on the button face. */ switch (myCounter) { case 0: panel1->DockPadding->All = 0; button1->Text = S"Start"; break; case 1: panel1->DockPadding->Top = 10; button1->Text = S"Top"; break; case 2: panel1->DockPadding->Bottom = 10; button1->Text = S"Bottom"; break; case 3: panel1->DockPadding->Left = 10; button1->Text = S"Left"; break; case 4: panel1->DockPadding->Right = 10; button1->Text = S"Right"; break; case 5: panel1->DockPadding->All = 20; button1->Text = S"All"; break; } myCounter++; }
