Ajax Control Toolkit - Controls Disabled In ToolBox

I Downloaded Visual Web Express And Ajax Control Toolkit. I Installed The Toolkit As Described HERE. But Nothing Appeared On My Toolbox. Thinking That I Might Have Missed Something, I Tried To Repeat The Process. When I Was Giving The Name During The Tab Creation Step, VWD Responded By Saying That Tab Name "AJAX Toolkit" Already Exists.

I Was Surprised To Know That The Tab Has Been Successfully Created But It Was Not Dislayed. Then By Just Playing Around With Different Options, I Clicked 'Show All'  Option Of Toolbox . Checking This Option Showed Me A Number Of Tabs Which I Haven't Seen Earlier.  Look At Belows Two Pictures.

This Also Showed Me My 'Ajax Toolkit' Tab. But All The Controls In This Tab Disabled. I Had Code View Of A aspx Page Opened On The Screen. Thinking That These Might Get Active On The Design View, I Switched To It. But This Did Not Worked.

Then I Restart VWD And Opened The Website Again. But Still These Are Grayed Out. So I Searched On Net It Gave Me Two Solutions As Given Below:

Solution 1:

• Restart Visual Web Express. If it does not work,
• Restart the PC.

Solution 2:

• Close VWb and any other express product installed running such as Visual C# EE.
• Open windows explorer and navigate to the 'C:\Documents and Settings\<your user name>\Application Data\Microsoft\VWDExpress\9.0' folder. 
• You might have to enable 'Show Hidden Files' under the folder options' View tab.
• Delete any .pdb file, you found in this folder.
• Start VWD and reinstall.

 But None Of Them Helped Me....

But Finally I Got How To Make Controls Enabled From One Of My Experience Friend. Which Is Described Below.

Solution 3:

• Open Visual Web Developer And Create A New Website....
• And Right Click In Solution Explorer And Select "Start Options...."

• Now It Will Open One Window As Shown Below....

• Now In Above Window Select Build Option And In Target Framework Make It As .Net Framework 4
• Its All Done Now Your All Controls Will Become Enabled.
