    Can only use aggregate methods on properties which are numeric

    Hi,

    I have price stored in textbox property. I can't use numeric, because I need decimal places. When I try to use sum method on this property error "Can only use aggregate methods on properties which are numeric" occured.

    I really need sum on this property, what is the best solution for this? I hope there is better way then foreach.

     

    Thanks

    Could you show a code sample of what you are doing exactly?

    Samples - don't work: 

    var notworking_totalPrice = Model.Children.Sum("priceTotal"); //don't work

    priceTotal is textstring property (because I need decimal places)

    This works, but it's boring:

    decimal totalPrice = 0;
foreach (var item in Model.Children)
{
    totalPrice += decimal.Parse(item.priceTotal);        
}
