The value of the property 'require' is null

DavidKucharski — Tue, 07 Mar 2017 20:45:13 GMT

I have created a ASP .NET Web Application. I add a new Web Form and put the following code in the aspx page. This is the example in the getting started 2d example on the ESRI web-site. When I run the application I get an error stating 'The value of the property 'require' is null or undefined., not a Function object. Am I doing something wrong or do I need something else. I thought it was a DOM object and having the <script src="https://js.arcgis.com/4.3/"></script> tag would make it accessible. Thanks

David,

What is your compatibility mode set to in your apps meta tag?

Robert,

thank you for pointing me in the right direction. My site, for other reasons, was in Compatibility mode. Once I put the meta tag on the mapping site to be compatible with IE 11 it works.
