Sometimes wee need to create a runtime contols. In dot net it is very easy to create them. You can create a control and add at runtime as follows:

Step1:
Declare a control as globaly for that page. Because if you are not declare that control as globaly then you can't access them in another funtion scope.

Button bttchk=new Button();

Step2:
Now you can provide there id and value at any event of controls of page. Like if you want to create the control at page load time, then you can write them as follows:

bttchk.id="MybttId"; // provide the id of button.
bttchk.Text="Runtime Button"; // Set the text of button.
bttchk.ToolTip="Runtime Created"; // Set the tooltip of button.
// LIke this you can set another properties of this button control. like : back color, forcolor , style etc.

Step3:
Now most important thing : How to work on click of this button. So for this add the following line of code:

// Set the click event of button.

bttchk.Click+=new EventHandler(bttchk_Click);

// Now add this "bttchk" button on page as follows:

Page.Form.Controls.Add(bttchk);

Now question is arising that what is "bttchk_click". Actualy this is a function which will be call on this button click. You can write this function as below:

protected void bttchk_Click(object sender, EventArgs e)
{
// At this place you can perform any action which you want.
//Here I am create a new textbox control on "bttchk" button click.

TextBox txt = new TextBox(); // Create a new textbox.
txt.Text = bttchk.Text; // Set the text of textbox control as bttchk button contol name.
Page.Form.Controls.Add(txt); // Now add this contol on page.
}
