  <asp:TextBox ID="txtID" runat="server"></asp:TextBox>

  <asp:TextBox ID="txtName" runat="server"></asp:TextBox>

  i have HTML in data base and i retrive it in cs file at any event(i.e int, preint or load).the html is like following

   <table style=" width:50%; background-color:lightGray;">

         <tr><td></td> <td>[txtID]</td></tr>

         <tr><td></td><td>[txtName]</td></tr>

  </table>

  NOW i want to replace [txtID] with <asp:TextBox ID="txtID" runat="server"></asp:TextBox>

  and [txtName] with <asp:TextBox ID="txtName" runat="server"></asp:TextBox>

  Hi,

  I think you can do that , we will use  Control.RenderControl() method to generate HTML output 

  here a code that makes things clear

  // from your db
              string html = @"<table style="" width:50%; background-color:lightGray;""><tr><td></td> <td>[txtID]</td></tr><tr><td></td><td>[txtName]</td></tr></table>";
              //
              TextBox txtID = new TextBox();
              TextBox txtName = new TextBox();
  
              StringBuilder sb = new StringBuilder();
              StringWriter sr = new StringWriter(sb);
              HtmlTextWriter tw = new HtmlTextWriter(sr);
  
              txtID.RenderControl(tw);
              string txtIDOutout = sb.ToString();
  
              sb.Clear();
              
              txtName.RenderControl(tw);
              string txtNameOutout = sb.ToString();
  
              html = html.Replace("[txtID]", txtIDOutout);
              html = html.Replace("[txtName]", txtNameOutout);
  
              Literal1.Text = html;

  Hi,

  to handle events , you can create event handlers programmatically

  for example :

  btnOk.click =+ MyEventHandler;  (the signature of MyEventHandler must be the same with event click).

  or btnOk.click =+ new EventHandler(MyEventHandler); (EventHandler is a delegate).
