Hi,

I'm trying to do an if like statement with the ClientTemplate Formatting, for basic usage this works:

#= (Location == "") ? 'N/A' : Location #

 

If the Location is empty it Displays N/A as needed, but if i try and make it a bit more advanced for another field i.e:

#= (AssignedToPhone == "") ? 'N/A' : '<a href="tel:AssignedToPhone" class="btn-link">AssignedToPhone</a>' #

 

I don't get any errors, but it renders as a link with the text as AssignedToPhone, how do i get it to show the actual value? I have also tried:

#= (AssignedToPhone == "") ? 'N/A' : '<a href="tel:#=AssignedToPhone#" class="btn-link">#=AssignedToPhone#</a>' #

 

This causing an error, and no render happens "Uncaught Error: Invalid template:' (then a bunch of HTML)"

After relaxing for a bit and re thinking i could see the issue and here's the result:

#= (AssignedToPhone == "" || AssignedToPhone == null) ? 'N/A' : '<a href="tel:' + AssignedToPhone + '" class="btn-link">' + AssignedToPhone + '</a>' #

 

Now prints N/A if empty or null otherwise it prints a hyperlink with the phone number! :)

Hi Lee,

Thank you for sharing the latest version that you have undertaken in order to resolve the case with our community. 

Indeed, for more complex scenarios, you could make use of a JavaScript function to handle the template.

https://docs.telerik.com/kendo-ui/framework/templates/overview#handling-external-templates-and-expressions

In the current case, it would be similar to:

.ClientTemplate("#=myFunc(data)#") // where the data is the data item for the current row

 

Kind regards,
