A cursor is a small picture whose location on the screen is controlled by a pointing device, such as a mouse, pen, or trackball. When the user moves the pointing device, the operating system moves the cursor accordingly.

Different cursor shapes are used to inform the user what operation the mouse will have. For example, when editing or selecting text, a Cursors.IBeam cursor is typically displayed. A wait cursor is commonly used to inform the user that a process is currently running. Examples of processes you might have the user wait for are opening a file, saving a file, or filling a control such as a DataGrid, ListBox or TreeView with a large amount of data.

All controls that derive from the Control class have a Cursor property. To change the cursor displayed by the mouse pointer when it is within the bounds of the control, assign a Cursor to the Cursor property of the control. Alternatively, you can display cursors at the application level by assigning a Cursor to the Current property. For example, if the purpose of your application is to edit a text file, you might set the Current property to Cursors.WaitCursor to display a wait cursor over the application while the file loads or saves to prevent any mouse events from being processed. When the process is complete, set the Current property to Cursors.Default for the application to display the appropriate cursor over each control type.


If you call Application.DoEvents before resetting the Current property back to the Cursors.Default cursor, the application will resume listening for mouse events and will resume displaying the appropriate Cursor for each control in the application.

Cursor objects can be created from several sources, such as the handle of an existing Cursor, a standard Cursor file, a resource, or a data stream.


The Cursor class does not support animated cursors (.ani files) or cursors with colors other than black and white.

If the image you are using as a cursor is too small, you can use the DrawStretched method to force the image to fill the bounds of the cursor. You can temporarily hide the cursor by calling the Hide method, and restore it by calling the Show method.

The following code example displays a form that demonstrates using a custom cursor. The custom Cursor is embedded in the application's resource file. The example requires a cursor contained in a cursor file named MyCursor.cur. To compile this example using the command line, include the following flag: /res:MyCursor.Cur, CustomCursor.MyCursor.Cur

using System;
using System.Drawing;
using System.Windows.Forms;

namespace CustomCursor
    public class Form1 : System.Windows.Forms.Form
        static void Main() 
            Application.Run(new Form1());

        public Form1()
            this.ClientSize = new System.Drawing.Size(292, 266);
            this.Text = "Cursor Example";

            // The following generates a cursor from an embedded resource.

            // To add a custom cursor, create a bitmap
            //        1. Add a new cursor file to your project: 
            //                Project->Add New Item->General->Cursor File

            // --- To make the custom cursor an embedded resource  ---

            // In Visual Studio:
            //        1. Select the cursor file in the Solution Explorer
            //        2. Choose View->Properties.
            //        3. In the properties window switch "Build Action" to "Embedded Resources"

            // On the command line:
            //        Add the following flag:
            //            /res:CursorFileName.cur,Namespace.CursorFileName.cur
            //        Where "Namespace" is the namespace in which you want to use the cursor
            //        and   "CursorFileName.cur" is the cursor filename.

            // The following line uses the namespace from the passed-in type
            // and looks for CustomCursor.MyCursor.Cur in the assemblies manifest.
	    // NOTE: The cursor name is acase sensitive.
            this.Cursor = new Cursor(GetType(), "MyCursor.cur");  


The following code example displays customer information in a TreeView control. The root tree nodes display customer names, and the child tree nodes display the order numbers assigned to each customer. In this example, 1,000 customers are displayed with 15 orders each. The repainting of the TreeView is suppressed by using the BeginUpdate and EndUpdate methods, and a wait Cursor is displayed while the TreeView creates and paints the TreeNode objects. This example requires that you have a cursor file named MyWait.cur in the application directory. It also requires a Customer object that can hold a collection of Order objects, and that you have created an instance of a TreeView control on a Form.

// The basic Customer class.
public class Customer : System.Object
   private string custName = "";
   protected ArrayList custOrders = new ArrayList();

   public Customer(string customername)
      this.custName = customername;

   public string CustomerName
      get{return this.custName;}
      set{this.custName = value;}

   public ArrayList CustomerOrders 
      get{return this.custOrders;}

} // End Customer class 

// The basic customer Order class.
public class Order : System.Object
   private string ordID = "";

   public Order(string orderid)
      this.ordID = orderid;

   public string OrderID
      get{return this.ordID;}
      set{this.ordID = value;}

} // End Order class

// Create a new ArrayList to hold the Customer objects.
private ArrayList customerArray = new ArrayList(); 

private void FillMyTreeView()
   // Add customers to the ArrayList of Customer objects.
   for(int x=0; x<1000; x++)
      customerArray.Add(new Customer("Customer" + x.ToString()));

   // Add orders to each Customer object in the ArrayList.
   foreach(Customer customer1 in customerArray)
      for(int y=0; y<15; y++)
         customer1.CustomerOrders.Add(new Order("Order" + y.ToString()));    

   // Display a wait cursor while the TreeNodes are being created.
   Cursor.Current = new Cursor("MyWait.cur");

   // Suppress repainting the TreeView until all the objects have been created.

   // Clear the TreeView each time the method is called.

   // Add a root TreeNode for each Customer object in the ArrayList.
   foreach(Customer customer2 in customerArray)
      treeView1.Nodes.Add(new TreeNode(customer2.CustomerName));

      // Add a child treenode for each Order object in the current Customer object.
      foreach(Order order1 in customer2.CustomerOrders)
           new TreeNode(customer2.CustomerName + "." + order1.OrderID));

   // Reset the cursor to the default for all controls.
   Cursor.Current = Cursors.Default;

   // Begin repainting the TreeView.
