Web Forms :: Error - Type MasterPage2 Already Contains A Definition For Head
May 7, 2015
Each time I build my MasterPage.master.aspx, I get an error that reads: The type 'MasterPage2' already contains a definition for 'head'This error appears for all the protected values in my MasterPage.master.cs file. Below is my MasterPage.master.aspx codes:
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">
<title>Untitled Page</title>
[Code] ....
And here is my MasterPage.master.cs code:
using System;using System.Web;using System.Web.Profile;using System.Web.UI;
using System.Web.UI.HtmlControls;using System.Web.UI.WebControls;
public partial class MasterPage2 : System.Web.UI.MasterPage{
protected ContentPlaceHolder head; protected HtmlAnchor A1;
I have several hundred html files that I want to remove the <head></head> tag from and all information contained in the tag. I am fairly sure I can do this in Visual Studio using the Find and Replace In Files with REGEX.
I'm getting this error: inboxcontrol_ascx does not contain a definition for DeleteMsg and no extension method DeleteMsg_click accepting a first argument of type asp.inboxcontrol could be found (are you missing a using directives or an assembly reference?)example:

I have a gridview which I'm trying to get the display of phonenumbers listed in a certain display format; (xxx) xxx-xxxx.If I have the code such as this, it displays the unformatted phone number and (000) 000-0000 for the null items.
I keep getting the error: Error message: CS0101: The namespace '<global namespace>' already contains a definition for 'checkvalue'. Then, I rename the Inherits from the @page directive in both the .aspx and .aspx.cs pages and it works! My website has only 2 pages, and both use the same class (same class name, exactly same syntax) but it has been copied and pasted and the 2 aspx pages (and aspx.cs pages) are not referencing each other. In other words, both aspx.cs pages (called page1.aspx.cs and page2.aspx.cs) has the class
public class CheckValue { //content return true; }
Both the aspx pages reference the 'inherits' files seperately:

I have an asp.net web site where I'm trying to resolve what looks like a problem with ASP.NET AJAX:
Microsoft JScript runtime error: Sys.ArgumentTypeException: Object of type 'Sys.Extended.UI.AccordionBehavior' cannot be converted to type 'Sys.UI.Behavior'. Parameter name: instance
I've googled around a lot, and looked at the code presented (see below, no idea what it means) but no luck.
I've tried changing scriptmanger scriptmode to release, and a bunch of other things too.
Details:
Visual Studio 2010 ASP.NET 4.0 Ajax control toolkit 4.0 jQuery 1.4.2 jQuery UI 1.8.5
JS Code the error occurs in, inside ScriptResource.axd:
dispose:function() { var c=this; b.UI.Behavior.callBaseMethod(c,eb); --------- this line var d=c._element; if(d) { var f=c.get_name(); if(f) d[f]=a; var e=d._behaviors; Array.remove(e,c); if(!e.length) d._behaviors=a; delete c._element } }
*Update: * Added accordion control declaration as requested, is there anything else I can add that could be useful?
Does anyone have any idea about this error at all - am I right in thinking it's MS AJAX not playing nicely with other javascript (probably jQuery UI) on the page?
I seem to be having issues with posting forms with DropDownLists. I've looked all over the net and tried various solutions, but none seem to work for me.
I'm getting the following error: The parameter conversion from type 'System.String' to type 'Models.Organization' failed because no type converter can convert between these types.
Here's my ViewModel:
[Code]....
Here's my controller:
[Code]....
The objects are generated by ADO.NET Entity Framework. Organizations is its own object, but also a property of Profile (each user belongs to one organization). Now I understand what the error message is saying, just not sure how else I'm supposed to do this.
I'm using a html helper that i got from here: [URL] here is my modified version (using SelectListItem):
public static string CheckBoxList(this HtmlHelper htmlHelper, string name, List<SelectListItem> listInfo) { return htmlHelper.CheckBoxList(name, listInfo, ((IDictionary<string, object>)null)); } public static string CheckBoxList(this HtmlHelper htmlHelper, string name, List<SelectListItem> listInfo, object htmlAttributes) { return htmlHelper.CheckBoxList(name, listInfo, ((IDictionary<string, object>)new RouteValueDictionary(htmlAttributes))); } public static string CheckBoxList(this HtmlHelper htmlHelper, string name, List<SelectListItem> listInfo, IDictionary<string, object> htmlAttributes) { if (String.IsNullOrEmpty(name)) throw new ArgumentException("The argument must have a value", "name"); if (listInfo == null) throw new ArgumentNullException("listInfo"); if (listInfo.Count < 1) throw new ArgumentException("The list must contain at least one value", "listInfo"); StringBuilder sb = new StringBuilder();................
I can't seem to figure out why this always throws an error: CS1928: 'System.Web.Mvc.HtmlHelper<DataLayer.BlogPost>' does not contain a definition for 'CheckBoxList' and the best extension method overload 'HtmlHelpers.HtmlHelpers.CheckBoxList(System.Web.Mvc.HtmlHelper, string, System.Collections.Generic.List<System.Web.Mvc.SelectListItem>)' has some invalid arguments
I am LINQ querrying against a datatable. However, I am unsuccessfull with catching null values. Here is my code that is giving me the following error.

I am checking to see if minperc is null. However to check that it still is trying to convert the value to double. Cant figure out a way around it. Here is the error: Cannot cast DBNull.Value to type 'System.Double'. Please use a nullable type.
I'm successfully using a masterpage for all my .aspx's... the below is typical... where though can I place script such as this into my .aspx below since I don't really use a head/body?:
I've never had to dynamically change the head of a webpage before and can't quite seem to get it. As mentioned in the title, the webpage is the child of a very simple master page. Here's what i've got:
