[Solved] Ajax aggregate

[Rafael]

I have nested grid with VacDuration column. 
It works fine when nested grid isn't empty

columns.Bound(v => v.VacDuration).Title("Duration").ReadOnly(true)
                            .Aggregate(agr=>agr.Sum())
                            .ClientFooterTemplate("Total: <#= $.telerik.formatString('{0:0}', Sum)#>")


BUT, I get JavaScript exception in function below when nested grid doesn't contain any row

function anonymous(data) {
var p=[];with(data){p.push('Total: ', $.telerik.formatString('{0:0}', Sum),'');}return p.join('');
}

Please advise what was missed

I'v got the exact same problem, does anyone know a solution?

columns.Bound(c => c.Days).Title(

 

"Working Days").Width(40).HtmlAttributes(new { style = "text-align:center" })

.Aggregate(aggreages => aggreages.Sum()).ClientFooterTemplate(

 

"<#= $.telerik.formatString('{0}', Sum)#>").FooterHtmlAttributes(new { style = "text-align:right; color:red" });
