Hello,

How can we create web controls dynamiclly?
How can we change the size of the controls such as height dynamically?

It is very easy to do it,if you learn DOT NET clearly.
So study it clearly first, then come to do project

Hi,
You can dynamically create web Control..
public class WebForm1 : System.Web.UI.Page
{
// Added by hand; will create instance in OnInit.
protected System.Web.UI.WebControls.TextBox TextBox1;
protected System.Web.UI.WebControls.TextBox TextBox2;

override protected void OnInit(EventArgs e)
{
// Create dynamic controls here.
// Use "using System.Web.UI.WebControls;"
TextBox1 = new TextBox();
TextBox1.ID = "TextBox1";
TextBox1.Style["Position"] = "Absolute";
TextBox1.Style["Top"] = "25px";
TextBox1.Style["Left"] = "100px";
form1.Controls.Add(TextBox1);

TextBox2 = new TextBox();
TextBox2.ID = "TextBox2";
TextBox2.Style["Position"] = "Absolute";
TextBox2.Style["Top"] = "60px";
TextBox2.Style["Left"] = "100px";
form1.Controls.Add(TextBox2);
//
// CODEGEN: This call is required by the ASP.NET Web Form Designer.
//
base.OnInit(e);
}

This code dynamically creates two TextBox controls, sets their IDs and positions, and then binds them to the Form Controls collection. The code also wires up the TextChanged events of the text boxes to a handler (TextBox_TextChanged).
private void Page_Load(object sender, System.EventArgs e)
{
if(!IsPostBack)
{
// Set the initial properties for the text boxes.
TextBox1.Text = "TextBox1";
TextBox2.Text = "TextBox2";
}
}
}

private void Page_Load(object sender, System.EventArgs e)
{
CheckBox _checkbox = new CheckBox();
_checkbox.ID = "chkDynamicCheckBox";
_checkbox.Text = "This is a dynamically generated checkbox";

Panel1.Controls.Add (_checkbox);
}

(or)
private void Page_Load(object sender, System.EventArgs e)
{
for ( int i = 0; i < 5; i++ )
{
TableRow tr = new TableRow();
// Create column 1
TableCell td1 = new TableCell();
// Create a label control dynamically
Label _label = new Label();
_label.ID = "lbl" + i.ToString();
_label.Text = "Enter Value " + i.ToString();
// Add control to the table cell
td1.Controls.Add(_label);

// Create column 2
TableCell td2 = new TableCell();
TextBox _text = new TextBox();
_text.ID = "txt_" + i.ToString();
// Add control to the table cell
td2.Controls.Add(_text);
// Add cell to the row
tr.Cells.Add(td1);
tr.Cells.Add(td2);
// Add row to the table.
tblDynamic.Rows.Add(tr);
}
}
