Hello,

I apologize for any inconvenience this problem may have caused you.

After I reviewed your project, I didn’t find any configuration that have set the “RenderingMode” property to “HTML5” mode.

In “Web.config” page, you set the WebGrid’s RenderingMode property to “XHTML”.
I also didn’t found any RenderingMode property in your WebGrid pages (Basic.aspx; FirstExperince.aspx; FlatGrid.aspx & StockExchange.aspx).
In “DefaultMaster.master” page, you use HTML4 Doctype, not HTML5 Doctype.

Therefore I created a new website using “Intersoft Empty Web Site” project template and .NET Framework 4.5.1 (NewWebSite.png).

In “Default.aspx” page, I added a WebGrid. I set the “RenderingMode” property to “HTML5”.
I bound the WebGrid to access data source (Northwind.mdb database & Shippers table).
I run the WebGrid page on Internet Explorer 11 browser, but unfortunately, it works fine on my end (WebGrid8_IE11_Net451.png).

I will also provide you, my new project. You could get the website from this link: http://1drv.ms/ZWK4Cf
Please kindly have review on the project to see the result.
Please kindly try to update your WebGrid assembly version & Intersoft Framework assembly version to the latest version as well (v8.0.7200.261 & v3.0.5000.912).

Thank you for your help.

Regards,
Hans K.

Hi Hans,

Thank you for your replay.  

I had problem with attaching my sample yesterday and probably missed the HTML5 setting while making new sample with smaller size for uploading.

I tried your project and I still see the exact same issue on my side. Attached is a result that I see on Firefox and IE11 (webGrid_FFnIE.png).

This issue happens if I have .NET Framework 4.5.1 installed on my server. Please see attachment "webGrid_InstalledPrograms.png"

If I remove .NET FW 4.5.1, Web Grid works fine on IE11. would you confirm that you also have the same framework installed.

Thanks,

Hello,

Thank you for the reply.

I have installed Microsoft .NET Framework 4.5.1 on my end. Please see attachment “NetFramework451.png”.

To ensure that the .NET Framework 4.5.1 has been installed on my end, I tried to download the .NET Framework 4.5.1 installer from this link.
However I got a warning message while trying to install the .NET Framework 4.5.1 on my end. Please see attachment “InstallingNetFramework451.png”.

Are you using the same installer .NET Framework 4.5.1 like mine?

Could you inform me information about your current WebGrid assembly version & Intersoft Framework assembly version?
Is there more information regarding your environment that related with your issue? So that I can replicate your issue on my end.

Thank you.

Regards,
Hans K.
