I'm making a couple of assumptions here:
1. You're using Visual Studio.
2. This is a Winforms project.

One simple, albeit slightly hacky, way is to create the controls you want at design time and copy and paste the code generated in the "designer" classes into a method you will call at run time. Then just delete the controls from visual designer.

Solution 2

Create the control and add it to parent container..

TextBox tb = new TextBox();

panel.Controls.Add(tb);

You should also need to set properties to the control to position it correctly.

Cheers
:cool:

DropDownList ddlday = new DropDownList();
DropDownList ddlmonth = new DropDownList();
DropDownList dllyear = new DropDownList();
Button btn = new Button();
Label lbl = new Label();
lbl.ID = "lbl";
lbl.Text = "date";
dllyear.ID = "ddlyear";
ddlmonth.ID = "ddlmonth";
ddlday.ID = "ddlday";
btn.ID = "btnsave";
btn.Text = "Save";
for (int i = 1; i < 32; i++)
{
ddlday.Items.Add(i.ToString());
}
for (int i = 1; i < 13; i++)
{
ddlmonth.Items.Add(i.ToString());
}
for (int i = System.DateTime.Now.Year - 20; i < System.DateTime.Now.Year + 1; i++)
{
dllyear.Items.Add(i.ToString());
}

Panel1.Controls.Add(ddlday);
Panel1.Controls.Add(ddlmonth);
Panel1.Controls.Add(dllyear);
btn.Click += new EventHandler(btnsave_Click);
Panel1.Controls.Add(btn);
