参考线程 - IE10 - 无法获取属性'PageRequestManager'未定义或空引用 [ ^ ]



另外 - 无法获取未定义或空引用的属性'PageRequestManager'[ ^ ]



我想你需要申请一些固定。

I am getting below error while I am using Script Manger control in Asp.net 4.5 Project.
Unable to get property 'PageRequestManager' of undefined or null reference.

If I am using Ajax Tool Script Manger control I am not getting that error.

Why is that happening only in case of Script Manager control alone?

and what is the solution?

Refer the thread - IE10 - Unable to get property 'PageRequestManager' of undefined or null reference[^]

Also - Unable to get property ‘PageRequestManager’ of undefined or null reference[^]

I think you need to apply some fix.
