Gets or sets which SplitContainer borders are attached to the edges of the container.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
You can dock a SplitContainer to any edge of its container, or you can dock a SplitContainer to all edges of the container so that the SplitContainer entirely fills the container. For example, set this property to DockStyle::Left to attach the left edge of the SplitContainer to the left edge of its container. Controls are docked in z-order.
The z-order corresponds to the depth dimension of the screen, and the x-order and y-order corresponds to the horizontal and vertical dimensions, respectively. Z-order defines which object appears in front of which, in cases where controls or windows can overlap or occupy the same space on the screen. A control or window at the top of the z-order appears on top of all other controls or windows and is referenced by an index of 0 in the Controls property. A control or window at the bottom of the z-order appears underneath all other controls or windows and is referenced by an index of (Controls.Count-1) in the Controls property.
For more information about anchoring and docking controls, see How to: Create a Multipane User Interface with Windows Forms.
The following code example shows a vertical splitter whose property is set to Fill. Other basic properties of a vertical splitter are also shown. This example is part of a larger example provided for the SplitContainer class.
// Basic SplitContainer properties. // This is a vertical splitter that moves in 10-pixel increments. // This splitter needs no explicit Orientation property because Vertical is the default. splitContainer1->Dock = System::Windows::Forms::DockStyle::Fill; splitContainer1->ForeColor = System::Drawing::SystemColors::Control; splitContainer1->Location = System::Drawing::Point( 0, 0 ); splitContainer1->Name = "splitContainer1"; // You can drag the splitter no nearer than 30 pixels from the left edge of the container. splitContainer1->Panel1MinSize = 30; // You can drag the splitter no nearer than 20 pixels from the right edge of the container. splitContainer1->Panel2MinSize = 20; splitContainer1->Size = System::Drawing::Size( 292, 273 ); splitContainer1->SplitterDistance = 79; // This splitter moves in 10-pixel increments. splitContainer1->SplitterIncrement = 10; splitContainer1->SplitterWidth = 6; // splitContainer1 is the first control in the tab order. splitContainer1->TabIndex = 0; splitContainer1->Text = "splitContainer1"; // When the splitter moves, the cursor changes shape. splitContainer1->SplitterMoved += gcnew System::Windows::Forms::SplitterEventHandler( this, &Form1::splitContainer1_SplitterMoved ); splitContainer1->SplitterMoving += gcnew System::Windows::Forms::SplitterCancelEventHandler( this, &Form1::splitContainer1_SplitterMoving ); // Add a TreeView control to the left panel. splitContainer1->Panel1->BackColor = System::Drawing::SystemColors::Control; // Add a TreeView control to Panel1. splitContainer1->Panel1->Controls->Add( treeView1 ); splitContainer1->Panel1->Name = "splitterPanel1"; // Controls placed on Panel1 support right-to-left fonts. splitContainer1->Panel1->RightToLeft = System::Windows::Forms::RightToLeft::Yes;
