Question

I have many TextBox in a page.

I would like to know if there is a ways to check pro grammatically all input for this TextBox and

apply Server.HtmlEncode to each one.

So I do not need apply Server.HtmlEncode for every single String.

Thanks!

You’d need to create a utility method for that. Something on the lines of:

Simple version if no nested text controls present:

public Dictionary<string, string> ReturnsAllTextEnteredOnPage()
{
   Dictionary<string, string> allTextEnteredOnPage = new Dictionary<string, string>(); 
   foreach (var control in Page.Controls)
   {
      if (control is TextBox)
      {
         TextBox ctrl = (TextBox)control;
         allTextEnteredOnPage.Add(ctrl.ID, Server.HtmlEncode(ctrl.Text));
      }
   }
   return allTextEnteredOnPage;
}

A bit complex version which considers all the textboxes present on a page:

public Dictionary<string, string> ReturnsAllTextEnteredOnPage()
{
  Dictionary<string, string> allTextEnteredOnPage = new Dictionary<string, string>(); 
  var allControls = FlattenChildren(Page);
  var allTextControls = allControls.OfType<TextBox>();
  foreach(var textCtrl in allTextControls)
  {
     allTextEnteredOnPage.Add(textCtrl.ID, Server.HtmlEncode(textCtrl.Text));
  }
  return allTextEnteredOnPage;        
}

The above method uses a method called FlattenChildren which can be taken from here.

Secondly, I havent used an editor for typing that code..
