Correct way to do if statement in a client template?

[Scott]

I'm trying to put a conditional in a client template and can't figure out where in the docs this is addressed. Could you point me to the correct area? Here's the code that's not working. The conditional is "CanBeOverturned":

columns.Template(@<text></text>).ClientTemplate("<div>Reviewed Date : \\#=SubmissionDateString\\# | \\#=CorrectiveActionName\\# \\# if (CanBeOverturned == true) { <a href='javascript:var t=0;' onclick='javascript:return openOverturn(\"\\#=FeedbackFormId\\#\")' style='float:right;' class='openFeedbackForm')>+ Overturn</a> }</div>");

Thanks in advance for any help you can provide!

Hello Scott,

There is an if example at the very bottom of this documentation article. Please let us know if you still experience troubles with your implementation.

Hi Petyo,
I'm struggling with the syntax of this conditional statement. I've studied the online documentation but no success.
.ClientFooterTemplate("<div>Avg: # if(data.TotalSalesAmt.sum == 0) {#= kendo.toString(0,'P2'); #}# else {#= kendo.toString(data.TotalMarginAmt.sum / data.TotalSalesAmt.sum,'P2'); #}# </div>")

Hello,

As far as I see, there are some mismatched # symbols in your template. Try breaking the template to multiline string in order to debug it.

Breaking the statement up into separate lines was a good suggestion. This worked:
.ClientFooterTemplate("# if(data.TotalSalesAmt.sum == 0) " +
                                           "{# <div>Avg: #= kendo.toString(0,'P2') # </div>#} " +
                                           "else {# <div>Avg: #= kendo.toString(data.TotalMarginAmt.sum / data.TotalSalesAmt.sum,'P2') # </div> #}#")

Hi, Is there a #: (mightbeNull)??(nullAternative) #
I get a fail if i leave of the "#}# else {#" 
This is because I wanted to add in a comma if a additional field had a value eg Address3 is often empty where as Address1 always has the street details. Trying to apply what works in handlebars{} to this where there are hole in the docs :/

Hello Doug,

The suggested syntax is not supported in Kendo Templates. Could you please provide an example demonstrating the issues you are experiencing with the regular if-else statements? Maybe I will be able to suggest something to make it work.

Looking forward to your reply.

Would be nice to see the URL to the complete guide to 'KendoUI Template Syntax' so when you google those 3 key words you end up at https://docs.telerik.com/kendo-ui/framework/templates/overview

Hello Doug,

Could you please provide some additional information about your last post? Is there a broken link to the Template article? Or is the link not on the top of the Google results when you type the three keywords you mentioned?
