I have a web application in which i display some alert or information based on database. to display a new parameter or
some new fields i have to modify source code and then deploy the application. is there any way by which i can dynamically add parameters thorough admin module or any other method so that i should be able to display new fields on the fly.
Need urgent solution.

0	Hi Riyaz, The approach should be to get all columns to display from the database to UI layer and display to the UI based on what user has selected or what you have set to display (you can store your selected column somewhere in the text file or any other file). I have a similar example written in this article http://www.dotnetfunda.com/articles/show/1400/how-to-generate-gridview-columns-dynamically-based-on-user-selection. Have a look at above article, that must help. Thanks Regards, Sheo Narayan http://www.dotnetfunda.com Riyazhaider, if this helps please login to Mark As Answer. \| Alert Moderator

Below is a pseudo code e.g. 1.aspx <div id="myDiv" runat="server" /> 1.aspx.cs Page_Load() { var x = ""; string str = "<html><head></head><body><table border='1'><tr><td>Name</td><td>Age</td></tr>"; for(int i=0;i<10;i++) x =+ "<td>" + string.Concat("Name",i) + "</td><td>" + string.Concat("Age",i) + "</td>"; str+= x; str += "</table></body></html>"; //finally add it to the div tag myDiv.Controlls.Add(str); } Also you may follow the below links for more clarity http://www.codeproject.com/Articles/25573/Building-ASP-NET-Web-Pages-Dynamically-in-the-Code http://www.aspdotnet-suresh.com/2014/08/create-aspx-page-dynamically-in-asp-net-using-csharp-vbnet.html http://www.dotnetspider.com/resources/26301-How-create-ASPX-Page-Dynamically-A-Step.aspx https://msdn.microsoft.com/en-us/library/kyt0fzt1%28v=vs.140%29.aspx http://visualstudiomagazine.com/articles/2010/10/07/dynamically-add-controls-at-runtime.aspx http://www.aspsnippets.com/Articles/Create-dynamic-ASPX-page-in-ASPNet.aspx -- Thanks & Regards, RNA Team Riyazhaider, if this helps please login to Mark As Answer. \| Alert Moderator

  for(int i=0;i<10;i++)  

    x =+ "<td>" + string.Concat("Name",i) + "</td><td>" + string.Concat("Age",i) + "</td>";



  str+= x;

  str += "</table></body></html>";



 //finally add it to the div tag

  myDiv.Controlls.Add(str);

}
