Hi,

Im trying apply a navigation structure depending on the document type alias used.

Im checking if the pages have any children, and then the doc type alias.

Im running in to problems with duplicate nodes.

Any help would be grateful.

Martin

 @foreach (var childPage in home.Children.Where("Visible")) {
if (childPage.Children.Any()) {
    if(childPage.DocumentTypeAlias == "DocType-1" ) { <li class=""><a href="">Doc Type 1</a></li>
    }

    if(childPage.DocumentTypeAlias == "DocType-2" ) { <li class=""><a href="">Doc Type 2</a></li>
    }

    else { <li class=""><a href="">Any Doc Type</a></li>
    }
}
else { <li class=""><a href="">Any Doc Type</a></li>
} }

Hi Martin,

Could you try this code and see if it works like you wanted it to work.

@{ 
    var home = CurrentPage.AncestorOrSelf(1);

    foreach (var childPage in home.Children.Where("Visible")) {
        if (childPage.Children.Any()) {
            if(childPage.DocumentTypeAlias == "DocType1Alias" ) { 
                <li class=""><a href="">Doc Type 1</a></li>

                }

            if(childPage.DocumentTypeAlias == "DocType2Alias" ) { 
                <li class=""><a href="">Doc Type 2</a></li>
            }

            else { 
                <li class=""><a href="">Any Doc Type</a></li>
            }
        }
        else { 
            <li class=""><a href="">Any Doc Type</a></li>
        } 

    }   
}

Hope this helps,

/Dennis

Reformating your code for readability, you're probably getting the duplicates due to the 2 if statements

@foreach (var childPage in home.Children.Where("Visible")) {

  if (childPage.Children.Any()) {
      if(childPage.DocumentTypeAlias == "DocType-1" ) { 
        <li class=""><a href="">Doc Type 1</a></li>
      }

      if(childPage.DocumentTypeAlias == "DocType-2" ) {
        <li class=""><a href="">Doc Type 2</a></li>
      } else {
        <li class=""><a href="">Any Doc Type</a></li>
      }
  } else { 
    <li class=""><a href="">Any Doc Type</a></li>
  }

}

Now consider your doctype is DocType-1. That would satisfy TURE for the first IF

if(childPage.DocumentTypeAlias == "DocType-1" )  {
  <li class=""><a href="">Doc Type 1</a></li>
}

and also be rendered in the ELSE

if(childPage.DocumentTypeAlias == "DocType-2" )  {
  <li class=""><a href="">Doc Type 2</a></li>
} else {
  <li class=""><a href="">Any Doc Type (can also be Doc Type 1 again)</a></li>
}

Hence the double result.

Changing you're whole code block to this should fix things.

@foreach (var childPage in home.Children.Where("Visible")) {

  if (childPage.Children.Any()) {
      if(childPage.DocumentTypeAlias == "DocType-1" ) { 
        <li class=""><a href="">Doc Type 1</a></li>
      } else if(childPage.DocumentTypeAlias == "DocType-2" )  {
        <li class=""><a href="">Doc Type 2</a></li>
      } else {
        <li class=""><a href="">Any Doc Type</a></li>
      }
  } else { 
    <li class=""><a href="">Any Doc Type</a></li>
  } 

}

Also, the last else {} probably isn't needed. What would that render?

Resurrecting this one for Umbraco 7.15 at least (yep I know U8 and U9 are out), and maybe U8 will work too. The "IsDocumentType()" method worked nicely for me.
```
if(childPage.IsDocumentType("doctype-1") ) {
//Do something here
}else if(childPage.IsDocumentType("doctype-1") ) {
//Do something here
}else{//blah}
```
