ASP .NET Validators don’t work properly with Update Panel

Recently I am working on a project ASP .NET AJAX. Of course it is very common to have some validators in some forms to control the input values, and unfortunately I experienced problem with validators inside the Update Panel. The validators just don’t work properly as I am expected.

After google searching and here is the solution that I had found: ASP .NET AJAX Validators.

Firstly, downloads the validators.zip file and adds in the DLL into the /bin directory of your project. After that, include the following codes into the pages section of the web.config.

<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>


And the problem solved. Cheers!
