Macro in Web part visible field

Vasyl Chepil asked on April 26, 2016 10:51

I'm using next macro in web part visible field

{% CMSContext.Current.GlobalObjects.Users.Where("UserID="+ToInt(QueryString["UserId"], 0 )).FirstItem.IsExpertIn != "" #%}

but it doesn't work if IsExpertIn returns null.

How i need to modify my macro to handle situation when IsExpertIn returns null?

Hi Vasyl,

I think if IsExpertIn is string value, you should use:

{% !string.IsNullOrEmpty(CMSContext.Current.GlobalObjects.Users.Where("UserID="+ToInt(QueryString["UserId"], 0 )).FirstItem.IsExpertIn) %}

Following code covers both null and empty string values:

{% GlobalObjects.Users.Where("UserID="+ToInt(QueryString.GetValue("UserId"),0)).FirstItem.IsExpertIn.ToString()!="" %}
