    Get Document Type of Child

    I want to do is something like this:

    @foreach (var child in CurrentPage.Children) {
    switch (child.GetDocumentType){ // Obviously "GetDocumentType" doesn't exsist
        case "Type1":
            // Do magic stuff
            break;
        case "Type2":
            // Even more magic here
            break;
        ...
        ...
    }
}

    Apparently, you can't just type child.DocumentType, I've searched the forums and Google without any luck.

    By my own experiments (I'm fairly new to Umbraco) I found out that one way of getting the document type is to do: 

    @foreach (var child in CurrentPage.Children){
    Node n = new Node(child.Id);
    switch(n.NodeTypeAlias){
        ...
    }
}

    So my question is: Is this the best way to go to get the document type of a child?

    I'm trying to avoid doing an if..else if..else.

    Hi Nikola,

    you should use this DocumentTypeAlias

    so your code would be like:

    @foreach (var child in CurrentPage.Children) {
    switch (child.DocumentTypeAlias){ 
        case "Type1":
            // Do magic stuff
            break;
        case "Type2":
            // Even more magic here
            break;
        ...
        ...
    }
}

    Hey Ali!

    I tried that before and got a CS0151: A switch expression or case label must be a bool, char, string, integral, enum, or corresponding nullable type.

    BUT, I don't know why I didn't try this before, if I typecast it to string it works:

    switch((string)child.DocumentTypeAlias){
    ...
}

    Thanks for your help

    you are welcome Nikola.

    I am wondering what version of Umbraco are you using? because in V6 the output of child.DocumentTypeAlias is string.

    Thanks

    Ali

    I'm using 6.1.3.

    Why it's not returning a string is beyond me.

    I made a function of my switch-statement that looks like this:

    string getHtmlInput(DynamicPublishedContent dpc){
    string ret = "";
    switch(dpc.DocumentTypeAlias){
        ...
    }
    return ret;
}

    Here the DocumentTypeAlias outputs a string. I probably did something stupid before :)

    I noticed this:

    foreach (var child in CurrentPage.Children) {
    switch(child.DocumentTypeAlias) { ... } // NOT WORKING
}

foreach (var child in Model.Content.Children) {
    switch(child.DocumentTypeAlias) { ... } // WORKING!
}

    alright that makes sense now.

    because CurrentPage is dynamic type whereas the Model.Content is not.

    So the type of child.DocumentTypeAlias is unknown until runtime but the Switch statement needs to know the type before the runtime that's why you where getting error.

    in the 2nd foreach loop the child is not dynamic any more and Child.DocumentTypeAlias returns string

    hope it makes it clear.

    Cheers

    Ali
