Dynamically adding html control to a Page from a string
protected PlaceHolder plhEdit; public void btnCheck_Click(object sender, EventArgs
e) { LiteralControl editbtn = new LiteralControl(string.Format("<input type=\"button\" value=\"Edit\"
onclick=\"{0}\"
/>", scrpt)); plhEdit.Controls.Add(editbtn); } |

For example on a button click add a html button to a page from a string
created at run time. Literal control comes handy in this case because it could
hold desired html control as text. So in above code create a literal control
with text value as html control and add it into a placeholder.
