if/else problem

hello Our.Umbraco

I got a problem with my macro.

Here's the Code

@inherits Umbraco.Web.Macros.PartialViewMacroPage


@{ var selection = CurrentPage.Children.Where("Visible"); }

@if (selection.Any())
{
    var count = 0;

        foreach (var item in selection)
        {
            if(count % 2 == 0) 
            {
            <div class="row">           
            <div class="col-sm-1 col-xs-0">
            </div>
            <div class="col-sm-5 col-xs-12">
            <p class="text">@item.Datum</p>
            <label class="subtitle">@item.Anlass</label><br /><br />
            </div>
            }
            else
            {
                <div class="col-sm-5 col-xs-12 text">
                    <p class="text">@item.Datum</p>
                    <label class="subtitle">@item.Anlass</label><br /><br />
                </div>
            </div>
            }
        count++;
        }
}

my problem is, it doesn't read the "else" statement. It puts out "} else {". It looks like its putting it out as html and not reading it as a macro.

What did i do wrong?

i think i got it.. i have to put @: in front of every code that is HTML. like:

@inherits Umbraco.Web.Macros.PartialViewMacroPage


@{ var selection = CurrentPage.Children.Where("Visible"); }

@if (selection.Any())
{
    var count = 0;

        foreach (var item in selection)
        {
            if(count % 2 == 0) 
            {
            @:<div class="row">         
            @:<div class="col-sm-1 col-xs-0">
            @:</div>
            @:<div class="col-sm-5 col-xs-12">
            @:<p class="text">@item.Datum</p>
            @:<label class="subtitle">@item.Anlass</label><br /><br />
            @:</div>
            }
            else
            {
                @:<div class="col-sm-5 col-xs-12 text">
                    @:<p class="text">@item.Datum</p>
                    @:<label class="subtitle">@item.Anlass</label><br /><br />
                @:</div>
            @:</div>
            }
        count++;
        }
}

Hi Hubert

that is an intresting solution i never knew you could do that. :)

but it should work the other way.

looking at the code i think it's because you have a missing / extra div inside the if (relating to the <div class="row">)

if you move the first div outside of if and the lass div from the else.

   foreach (var item in selection)
        {
            <div class="row">           
              @if(count % 2 == 0) 
              {
                <div class="col-sm-1 col-xs-0">
                </div>
                <div class="col-sm-5 col-xs-12">
                   <p class="text">@item.Datum</p>
                   <label class="subtitle">@item.Anlass</label><br /><br />
                </div>
              }
              else
              {
                <div class="col-sm-5 col-xs-12 text">
                    <p class="text">@item.Datum</p>
                    <label class="subtitle">@item.Anlass</label><br /><br />
                </div>
              }
            </div>

then that should work (note the @ in front of the if statement now because it's inside the div)
