Problem:
I had faced this problem yesterday and found the solution of this, this problem was due to RenderDnLvlHTML, which worked fine in up-level browser and not worked correctly in
Down-level browser.
• uplevel browser - Internet Explorer 5 and later versions.
uplevel browser = IE
• downlevel browser - Any Non IE Browser except for Internet Explorer 5 and later versions.
downlevel browser = Non IE
Solution:
1- Include web-browser ASP.NET folder in your solution.
2- Add new .browser in this folder with name of "CriOS.browser" if you want to change the name you have to change it accordingly in following code.
3- Replace the exciting content from file with the following code.
<browsers>
<browser id="CriOS" parentID="Safari">
<identification>
<userAgent match="CriOS" />
</identification>
<capabilities>
<capability name="browser" value="CriOS" />
<capability name="ecmascriptversion" value="3.0" />
<capability name="javascript" value="true" />
<capability name="javascriptversion" value="1.7" />
</capabilities>
</browser>
</browsers>
4- Now take a look that problem has been resolved.
