SplitContainer.SplitterMoving Event

Occurs when the splitter control is in the process of moving.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
public event SplitterCancelEventHandler SplitterMoving

This event occurs only when the user moves the splitter control. It does not occur when you change the SplitterDistance property value programmatically.

For more information about handling events, see Consuming Events.

The following code example raises the SplitterMoving event, signified in this example by a change to the cursor style when you move the splitter. The SplitterMoved event is raised when you stop moving the splitter. This is signified in this example by the cursor style reverting to the default.

using System.Data;

public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.SplitContainer splitContainer1;

// Create an empty Windows form. 
public Form1()
	{
	InitializeComponent();
	}
	private void InitializeComponent()
	{
        splitContainer1 = new System.Windows.Forms.SplitContainer();
        splitContainer1.SuspendLayout();
        SuspendLayout();

        // Place a basic SplitContainer control onto Form1.
        splitContainer1.Dock = System.Windows.Forms.DockStyle.Fill;
        splitContainer1.Location = new System.Drawing.Point(0, 0);
        splitContainer1.Name = "splitContainer1";
        splitContainer1.Size = new System.Drawing.Size(292, 273);
        splitContainer1.SplitterDistance = 52;
        splitContainer1.SplitterWidth = 6;
        splitContainer1.TabIndex = 0;
        splitContainer1.Text = "splitContainer1";

        // Add the event handler for the SplitterMoved event.
        splitContainer1.SplitterMoved += new System.Windows.Forms.SplitterEventHandler(splitContainer1_SplitterMoved);

        // Add the event handler for the SplitterMoving event.
        splitContainer1.SplitterMoving += new System.Windows.Forms.SplitterCancelEventHandler(splitContainer1_SplitterMoving);

        // This is the left panel of the vertical SplitContainer control.
        splitContainer1.Panel1.Name = "splitterPanel1";

        // This is the right panel of the vertical SplitContainer control.
        splitContainer1.Panel2.Name = "splitterPanel2";

        // Lay out the basic properties of the form.
        ClientSize = new System.Drawing.Size(292, 273);

        Name = "Form1";
