How to create Controls at run time in CSharp .NET

Anonymous User5129 27-Jul-2010

Here I’ve tried to demonstrate how to create controls at runtime in C#.Net. To create controls at runtime we have to create object of each control and add them to form.

Example

Adding text box to form

TextBox txt = newTextBox();
//creating object of TextBox.
 txt.Location = new System.Drawing.Point(100, 30);
//setting location
  txt.Width = 200;
//setting width
  this.Controls.Add(txt);
//adding text box to form

Adding label to form

 Label lbl = newLabel();
//creating label object
  lbl.Text = "ID";
//setting text
  lbl.Location = newPoint(20, 35);
//setting location
 this.Controls.Add(lbl);
//adding label to form.
 
 TextBox txt1 = newTextBox();
 txt1.Location = new System.Drawing.Point(100, txt.Location.Y+txt.Height+10);
 txt1.Width = txt.Width;
 this.Controls.Add(txt1);
 
 Label lbl1 = newLabel();
 lbl1.Text = "Name";
 lbl1.Location = newPoint(20, txt1.Location.Y);
 this.Controls.Add(lbl1);
      
 Button btn = newButton();
 btn.Location = new System.Drawing.Point(txt1.Location.X+txt1.Width-btn.Width, txt1.Location.Y+txt1.Size.Height+5);
 btn.Text = "Click";
 this.Controls.Add(btn);
