IE Compatibility Mode - How to correct Domain Controller Policy

Hello Mike,
Separate IIS pool application that I developed with DX Controls no need older version like 7 or 8.
Some users have Win7 with IE10. Above method:
DevExpress.Web.ASPxClasses.ASPxWebControl.SetIECompatibilityModeEdge
is universal back fot IE10, 9, 8, 7  ?

In case of put in Global.asax:
protected void Application_AcquireRequestState(Object sender, EventArgs e) {
  DevExpress.Web.ASPxClasses.ASPxWebControl.SetIECompatibilityModeEdge();
}
Do I have to repeat this one in every PreInit event ?

Hello,

>>is universal back fot IE10, 9, 8, 7 ?

Yes, the ASPxWebControl.SetIECompatibilityModeEdge method is applicable here.

>>Do I have to repeat this one in every PreInit event ?

Prior to version 14.2, it is necessary to use the ASPxWebControl.SetIECompatibilityModeEdge method overload to accept the "pageOrMasterPage" parameter and render the corresponding trigger (meta/header):

Global.asax.cs:

C#
void Application_PreRequestHandlerExecute(object sender, EventArgs e) {  
    if(CurrentPage != null)  
        CurrentPage.PreInit += Page_PreInit;  
}  

static Page CurrentPage {  
    get { return HttpContext.Current.CurrentHandler as Page; }  
}  

static void Page_PreInit(object sender, EventArgs e) {  
    if (CurrentPage.Master != null) {  
        DevExpress.Web.ASPxClasses.ASPxWebControl.SetIECompatibilityModeEdge(CurrentPage.Master);  
    } else {  
        DevExpress.Web.ASPxClasses.ASPxWebControl.SetIECompatibilityModeEdge(CurrentPage);  
    }  
}  

Note that starting with the upcoming major version 14.2, we have significantly improved this functionality.
If you are not in a hurry, I suggest that you wait until a new version is available for download.

Hello,
Thank you Mike.

You are welcome, Waldemar.

Hello Mike,
We are working on 14.2.4 release.
Below code is working in our domain:
protected void Page_PreInit(object sender, EventArgs e)
{
   DevExpress.Web.ASPxWebControl.SetIECompatibilityMode(7);
}
I would to like to put this method globally in application, e.g. in global.asax.
How to do it correctly ?

Hello Waldemar,

Starting with version v2014 vol 2 (14.2), it is much easier to specify the target IE Compatibility Version with the help of a new ieCompatibilityVersion configuration option:

XML
<configuration>  
    <devExpress>  
        <settings ieCompatibilityVersion="7" />  
    </devExpress>  
</configuration>  

Hi Mike,
Working great. Thank you very much.
