How to remove a tab attribute in ASP .NET AJAX Toolkit using Regular Expression

Question

I have tried to remove the following tag generated by the AJAX Control toolkit. The scenario is our GUI team used the AJAX control toolkit to make the GUI but I need to move them to normal ASP .NET view tag using MultiView.

I want to remove all the __designer: attributes

Here is the code

<asp:TextBox ID="a" runat="server" __designer:wfdid="w540" />
<asp:DropdownList ID="a" runat="server" __designer:wfdid="w541" />
.....
<asp:DropdownList ID="a" runat="server" __designer:wfdid="w786" />

I tried to use the regular expression find replace in Visual Studio using:

Find:

:__designer\:wfdid="w{([0-9]+)}"

Replace with empty space

Can any regular expression expert help?

      string pattern = @"__designer:wfdid=""w\d+""";
      Regex rgx = new Regex(pattern);

      // Declare a string consisting of text and white spaces.
      string aspCode = @"<asp:TextBox ID=""a"" runat=""server"" __designer:wfdid=""w540"" />";

      // Replace runs of white space in the input string with a
      // comma and a blank.
      string outputStr = rgx.Replace(aspCode, ", ");

      // Display the resulting string.
      Console.WriteLine("Pattern:       \"{0}\"", pattern);
      Console.WriteLine("Input string:  \"{0}\"", aspCode);
      Console.WriteLine("Output string: \"{0}\"", outputStr);
     }
    }
}

If you want to get rid of __designer:mapid="22"

use this regex

<__designer\:mapid=:q
