Getting Started in Windows Forms ContextMenuStrip (ContextMenuStripEx)

24 Feb 20236 minutes to read

Starting with v16.2.0.x, if you refer to Syncfusion assemblies from trial setup or from the NuGet feed, include a license key in your projects. Refer to this link to learn about registering Syncfusion license key in your Windows Forms application to use our components.

This section provides a quick overview for working with the ContextMenuStripEx control in a WinForms application.

Dependent Assemblies

The following assemblies needs to be added as reference to use the control in any application.

  • Syncfusion.Tools.Windows
  • Syncfusion.Grid.Base
  • Syncfusion.Grid.Windows
  • Syncfusion.Shared.Base
  • Syncfusion.Shared.Windows
  • Syncfusion.Tools.Base

Adding a context menu through designer

The Windows Forms ContextMenuStrip (ContextMenuStripEx) control can be added through designer by following the below steps.

  1. Drag and drop the ContextMenuStripEx control from the toolbox (under the section “Syncfusion Windows Visual Studio Version Toolbox Essential Studio Version”) into the designer page.

  5. Once item is added, we can set the image by right-clicking on the particular item in the designer and select Properties. Now, in the Properties panel, under Appearance > Image we need to browse the respective image.



  6. Similarly, we can set the text for menu item in the Properties panel, under Appearance > Text section.


  7. To associate the context menu to a control we need to drag and drop any control of your choice to the application. In this illustration, we have used “RichTextBox”.

    To associate the ContextMenuStripEx control, you can choose any type of control like RichTextBox, Button, Label, TextBox, MaskedTextBox etc…

  9. Finally, we have populated the ContextMenuStripEx control successfully.


Adding a context menu through code

The ContextMenuStripEx control can be added through code by following the below steps.

  1. Add the following dependency assembly references to the project.

    • Syncfusion.Tools.Windows.dll
    • Syncfusion.Grid.Base.dll
    • Syncfusion.Grid.Windows.dll
    • Syncfusion.Shared.Base.dll
    • Syncfusion.Shared.Windows.dll
    • Syncfusion.Tools.Base.dll
    • Syncfusion.Licensing.dll

    You can get these assemblies by browsing to the default assembly location.
    {System Drive}: \Program Files (x86) \ Syncfusion\Essential Studio\ {Platform} \ {Build Version Number} \ precompiledassemblies \ {Framework Version Number}

  2. The below code snippets adds a ContextMenuStripEx control to the application.

    private Syncfusion.Windows.Forms.Tools.ContextMenuStripEx contextMenuStripEx;
    private System.Windows.Forms.ToolStripMenuItem toolStripMenuItem1;
    private System.Windows.Forms.ToolStripMenuItem toolStripMenuItem2;
    private System.Windows.Forms.ToolStripMenuItem toolStripMenuItem3;
    private System.Windows.Forms.RichTextBox richTextBox1;
    this.contextMenuStripEx = new Syncfusion.Windows.Forms.Tools.ContextMenuStripEx();
    this.toolStripMenuItem1 = new System.Windows.Forms.ToolStripMenuItem();
    this.toolStripMenuItem2 = new System.Windows.Forms.ToolStripMenuItem();
    this.toolStripMenuItem3 = new System.Windows.Forms.ToolStripMenuItem();
    this.richTextBox1 = new System.Windows.Forms.RichTextBox();
    //Associate the context menu
    this.toolStripMenuItem1.Image = System.Drawing.Image.FromFile(@"..\..\..\new.png");
    this.toolStripMenuItem2.Image = System.Drawing.Image.FromFile(@"..\..\..\copy.png");
    this.toolStripMenuItem3.Image = System.Drawing.Image.FromFile(@"..\..\..\cut.png");
    this.toolStripMenuItem1.Text = "New";
    this.toolStripMenuItem2.Text = "Copy";
    this.toolStripMenuItem3.Text = "Cut";
    this.contextMenuStripEx.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {this.toolStripMenuItem1,this.toolStripMenuItem2,this.toolStripMenuItem3,});
    this.richTextBox1.ContextMenuStrip = this.contextMenuStripEx;
    Private contextMenuStripEx As Syncfusion.Windows.Forms.Tools.ContextMenuStripEx
    Private toolStripMenuItem1 As System.Windows.Forms.ToolStripMenuItem
    Private toolStripMenuItem2 As System.Windows.Forms.ToolStripMenuItem
    Private toolStripMenuItem3 As System.Windows.Forms.ToolStripMenuItem
    Private richTextBox1 As System.Windows.Forms.RichTextBox
    Me.contextMenuStripEx = New Syncfusion.Windows.Forms.Tools.ContextMenuStripEx()
    Me.toolStripMenuItem1 = New System.Windows.Forms.ToolStripMenuItem()
    Me.toolStripMenuItem2 = New System.Windows.Forms.ToolStripMenuItem()
    Me.toolStripMenuItem3 = New System.Windows.Forms.ToolStripMenuItem()
    Me.richTextBox1 = New System.Windows.Forms.RichTextBox()
    'Associate the context menu
    Me.toolStripMenuItem1.Image = System.Drawing.Image.FromFile("..\..\..\new.png")
    Me.toolStripMenuItem2.Image = System.Drawing.Image.FromFile("..\..\..\copy.png")
    Me.toolStripMenuItem3.Image = System.Drawing.Image.FromFile("..\..\..\cut.png")
    Me.toolStripMenuItem1.Text = "New"
    Me.toolStripMenuItem2.Text = "Copy"
    Me.toolStripMenuItem3.Text = "Cut"
    Me.contextMenuStripEx.Items.AddRange(New System.Windows.Forms.ToolStripItem() {Me.toolStripMenuItem1,Me.toolStripMenuItem2,Me.toolStripMenuItem3})
    Me.richTextBox1.ContextMenuStrip = Me.contextMenuStripEx
