Thanks for the response. Which version of Infragistics WebDataMenu did you ise on your sample ?

We use lots of the 'classic' controls. We would have to migrate all the controls to the new framework. I've taken a look at the controls affected :

UltraWebGrid (which we will replace with Telerk Gird - after reviewing the new Grids in the Aikido framework

UltraWebListbar

UltraWebNavigator

UltraWebTab

WebCombo

Thanks Again. We need to find a solution to the IE 11 specific problem with the WebDataGrid which can be implemented in very quickly. Once options I may investigate is using a Java script to determine the browser and then set the width of the WebDataMenu when the Browser is IE. I don't know if this will work as IE have made the process more difficut (since IE10). However It would be a quick fix. We are a commercial software house and the issues with ASP.NET Infragisitics would require a big cost in our time to fix one issue on one control.

Hello,

Is this issue with WebDataGrid or WebDataMenu?

Please provide a working sample demonstrating the issue so I could propose a fix.

I am looking forward to hearing from you.

WebDataMen is the problem control.

I was hoping that I could use a JAVA Script function(perhaps on Initialise) to set the WIDTH (when the browser is IE11)
