Validators In AJAX UpdatePanel

For perform the validation into UpdatePanel of Ajax, you need make some tricks...

I made it works, with ASP.NET AJAX Release 1.0.

Just add the following lines in the web.config file:

<pages>

<tagMapping>
<add tagType="System.Web.UI.WebControls.CompareValidator" mappedTagType="Sample.Web.UI.Compatibility.CompareValidator, Validators, Version=1.0.0.0"/>
<add tagType="System.Web.UI.WebControls.CustomValidator" mappedTagType="Sample.Web.UI.Compatibility.CustomValidator, Validators, Version=1.0.0.0"/>
<add tagType="System.Web.UI.WebControls.RangeValidator" mappedTagType="Sample.Web.UI.Compatibility.RangeValidator, Validators, Version=1.0.0.0"/>
<add tagType="System.Web.UI.WebControls.RegularExpressionValidator" mappedTagType="Sample.Web.UI.Compatibility.RegularExpressionValidator, Validators, Version=1.0.0.0"/>
<add tagType="System.Web.UI.WebControls.RequiredFieldValidator" mappedTagType="Sample.Web.UI.Compatibility.RequiredFieldValidator, Validators, Version=1.0.0.0"/>
<add tagType="System.Web.UI.WebControls.ValidationSummary" mappedTagType="Sample.Web.UI.Compatibility.ValidationSummary, Validators, Version=1.0.0.0"/>
</tagMapping>
...
</pages>

Setup is unable to determine a valid ordering for the installation VS 2005

When I wanted recover a bit of free space on my HDD, I decided to uninstall some features of Visual Studio 2005. But it wasn't easy. I'm talking about release version.

The problem is the Visual Studio Installer doesn't know a self order for uninstall/install some components. But don't worry there is a manual way for do it.

I read this article. It works for VS 2005 too.
