There are different ways in which you can create dynamic control in ASP.NET.

Here i have given 5 different ways for creating Dynamic controls.

1 : [By using JavaScript]

------------------------------

By using javascript you can create Dynamic controls.

Code :

window.load = createDynamicControl;

function createDynamicControl()

{

document.write("<input type='text' name='txtJS' value='JavaScript Textbox' />");

}

2 : [By using ASP.NET Literal Control]

--------------------------------------

By using Literal control in ASP.NET you can create Dynamic Control.

<asp:Literal ID="ltrDynamicControl" runat="server" Text="I am Literal control" />

The output of the above code at the client end will be - I am Literal Control,

without having any additional tag.

So you can create dynamic controls using this control.

Code :

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

ltrDynamicControl.Text = "<input type='text' id='txtDynamicControl' runat='server' value='Literal Textbox' />";

}

3 : [By using ASP.NET Label Control]

------------------------------------

By using Label control in ASP.NET you can create Dynamic Control.

<asp:Label ID="lblDynamicControl" runat="server" Text="I am Label control" />

The output of the above code at the client end will be - <span>I am Label Control</span>,

means text will be enclosed with in <span></span> tag.

So you can create dynamic controls using this control.

Code :

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

lblDynamicControl.Text = "<input type='text' id='txtDynamicControl' runat='server' value='Label Textbox' />";

}

4 : [By using Response object in ASP.NET]

-----------------------------------------

By using Response object in ASP.NET you can create dynamic Control.
