http://stackoverflow.com/a/2260335/2745294[^]

C#

var configuration = WebConfigurationManager.OpenWebConfiguration("~");
var section = (ConnectionStringsSection)configuration.GetSection("connectionStrings");
section.ConnectionStrings["MyConnectionString"].ConnectionString = "Data Source=...";
configuration.Save();

C#

string path = Server.MapPath("~/Web.Config");
XmlDocument xDoc = new XmlDocument();
xDoc.Load(path);

// find a node - here the one with name='abc'
XmlNode node = doc.SelectSingleNode("/location[@name='YourTextBoxName']");

// if found....
if (node != null)
{
   // get its parent node
   XmlNode parent = node.ParentNode;

   // remove the child node
   parent.RemoveChild(node);

   // verify the new XML structure
   string newXML = doc.OuterXml;

   // save to file or whatever....
   doc.Save(path);
}

Hope this helps.

cant you just put empty string/"" in location & save the web.config file.

Member 11165607 3-Feb-15 4:59am

i don't understand, can you give a sample ?

Sushil Mate 3-Feb-15 5:00am

does this code works? can u you share web.config.

Sushil Mate 3-Feb-15 5:17am

this code is used for adding the new element in the file, not for deleting?

Member 11165607 3-Feb-15 5:19am
