Add control manually in code

To add the control manually in C#, follow the given steps:

  1. Add the Syncfusion.Shared.Base assembly reference to the project:

  2. Include the Syncfusion.Windows.Forms namespace.

    using Syncfusion.Windows.Forms;
    Imports Syncfusion.Windows.Forms
  3. Create a PopupControlContainer instance, and add it to the window.

    //Create instance of PopupControlContainer
    PopupControlContainer popupControlContainer1= new PopupControlContainer();
    'Create instance of PopupControlContainer
    Dim popupControlContainer1 As PopupControlContainer = New PopupControlContainer

Adding PopupControlContainer and element via code

  1. Add child controls like button, label, TextBox, ColorPicker, etc., to the PopupControlContainer.

    // Declaration 
    private Syncfusion.Windows.Forms.PopupControlContainer popupControlContainer1;
    private System.Windows.Forms.Button button1;
    private System.Windows.Forms.RichTextBox richTextBox1;
    // Initializing 
    this.popupControlContainer1 = new Syncfusion.Windows.Forms.PopupControlContainer();
    this.button1 = new System.Windows.Forms.Button();
    this.richTextBox1 = new System.Windows.Forms.RichTextBox();
    // popupControlContainer1
    this.popupControlContainer1.Location = new System.Drawing.Point(33, 58);
    this.popupControlContainer1.Name = "popupControlContainer2";
    this.popupControlContainer1.ParentControl = this.richTextBox1;
    this.popupControlContainer1.Size = new System.Drawing.Size(200, 100);
    // button1
    this.button1.Location = new System.Drawing.Point(13, 29);
    this.button1.Name = "button1";
    this.button1.Size = new System.Drawing.Size(174, 35);
    this.button1.Text = "PopupControlContainer";
    // richTextBox1
    this.richTextBox1.Location = new System.Drawing.Point(12, 12);
    this.richTextBox1.Name = "richTextBox1";
    this.richTextBox1.Size = new System.Drawing.Size(100, 96);
    this.richTextBox1.Click += RichTextBox1_Click1;
    // Form1
    this.ClientSize = new System.Drawing.Size(282, 253);
    this.Name = "Form1";
    this.Text = "Form1";   
    private void RichTextBox1_Click1(object sender, EventArgs e)
    Private popupControlContainer1 As Syncfusion.Windows.Forms.PopupControlContainer
    Private button1 As System.Windows.Forms.Button
    Private richTextBox1 As System.Windows.Forms.RichTextBox
    Me.popupControlContainer1 = New Syncfusion.Windows.Forms.PopupControlContainer()
    Me.button1 = New System.Windows.Forms.Button()
    Me.richTextBox1 = New System.Windows.Forms.RichTextBox()
    ' popupControlContainer1
    Me.popupControlContainer1.Location = New System.Drawing.Point(33, 58)
    Me.popupControlContainer1.Name = "popupControlContainer2"
    Me.popupControlContainer1.ParentControl = Me.richTextBox1
    Me.popupControlContainer1.Size = New System.Drawing.Size(200, 100)
    ' button1
    Me.button1.Location = New System.Drawing.Point(13, 29)
    Me.button1.Name = "button1"
    Me.button1.Size = New System.Drawing.Size(174, 35)
    Me.button1.Text = "PopupControlContainer"
    ' richTextBox1
    Me.richTextBox1.Location = New System.Drawing.Point(12, 12)
    Me.richTextBox1.Name = "richTextBox1"
    Me.richTextBox1.Size = New System.Drawing.Size(100, 96)
    Me.richTextBox1.Click += RichTextBox1_Click1
    ' Form1
    Me.ClientSize = New System.Drawing.Size(282, 253)
    Me.Name = "Form1"
    Me.Text = "Form1"
    Private Sub RichTextBox1_Click1(ByVal sender As Object, ByVal e As EventArgs)
    End Sub
