Custom Control - KeySortDropDownList

[Rea]

Hai,

I placed the scrip from web page Custom Control - KeySortDropDownList)
to my project ContactSearch.ascx.cs

Sours:
1. namespace vestinside.Controls
2. {
3. using System;
4. using System.Data;
5. using System.Drawing;
6. using System.Web;
7. using System.Web.UI.WebControls;
8. using System.Web.UI.HtmlControls;
9. using vestinside.DB;
10. using vestinside.Library;
11.
12.namespace Thycotic.Web.UI.WebControls
13.{
14.public class KeySortDropDownList : DropDownList
15.{
16......

After compiling I got the following error:
O:\localhost\Controls\ContactSearch.ascx.cs(12): Cannot use qualified namespace names in nested namespace declarations

Projekt: ASP.net C#

How to eliminate this error? Maybe I paste to bad place?
Thanks

You cannot nest the line

namespace Thycotic.Web.UI.WebControls

inside an already existing namespace.

How to make the script working?

When I delete namespace Thycotic.Web.UI.WebControls, the error has gone, but when I type to Dropdownlist 'ae' , I got in the first in the list 'a...' and then 'e...', but not 'ae....'"

How to make the script working?

namespace vestinside.Controls
{
	using System;
	using System.Data;
	using System.Drawing;
	using System.Web;
	using System.Web.UI.WebControls;
	using System.Web.UI.HtmlControls;
	using vestinside.DB;
	using vestinside.Library;

public class KeySortDropDownList : DropDownList
		{
			private readonly static string functionName = "KeySortDropDownList_onkeypress";
			private bool _caseSensitiveKeySort = false;

			public virtual bool CaseSensitiveKeySort 
			{
				get 
				{
					return _caseSensitiveKeySort;
				}
				set 
				{
					_caseSensitiveKeySort = value;
				}
			}

			protected override void OnLoad(System.EventArgs e) 
			{
				base.OnLoad(e);// call the base class method
				// define the client-side script
				string script = @"
<script language=""javascript"" type=""text/javascript"">
function " + functionName + @"(dropdownlist,caseSensitive) {
  // check the keypressBuffer attribute is defined on the dropdownlist 
  var undefined; 
  if (dropdownlist.keypressBuffer == undefined) { 
    dropdownlist.keypressBuffer = ''; 
  } 
  // get the key that was pressed 
  var key = String.fromCharCode(window.event.keyCode); 
  dropdownlist.keypressBuffer += key;
  if (!caseSensitive) {
    // convert buffer to lowercase
    dropdownlist.keypressBuffer = dropdownlist.keypressBuffer.toLowerCase();
  }
  // find if it is the start of any of the options 
  var optionsLength = dropdownlist.options.length; 
  for (var n=0; n < optionsLength; n++) { 
    var optionText = dropdownlist.options[n].text; 
    if (!caseSensitive) {
      optionText = optionText.toLowerCase();
    }
    if (optionText.indexOf(dropdownlist.keypressBuffer,0) == 0) { 
      dropdownlist.selectedIndex = n; 
      return false; // cancel the default behavior since 
                    // we have selected our own value 
    } 
  } 
  // reset initial key to be inline with default behavior 
  dropdownlist.keypressBuffer = key; 
  return true; // give default behavior 
} 
</script>";
				// register the client-side script block
				this.Page.RegisterClientScriptBlock(functionName,script);
				// add to the onkeypress event
				this.Attributes.Add("onkeypress","return " + functionName 
					+ "(this," + _caseSensitiveKeySort.ToString().ToLower() + ")");
			}
		}
