Hi..

I just wanted to know whether there is any way to get collection editor form
inside a another form , without using property grid, since my boss doesn't like the pop up coming up for collection editor, so without triggering any event the collection editor must be placed in a particular location of my form, which i can further edit and add items into the collection list.

Can anyone guide me how can i do this..

Instead of AxMSChart, I will use McShart for .NET 3.5, it's easy and fully managed code + documentation and sample.

If your not using .NET 3.5, have a look at ZedGraph[^] instead.

Cannot save changes to code programatically

I'm writing a VS add-on which, on activation, is supposed to add a couple of attributes in the App.xaml.
The problem I get is, when App.xaml is opened for editing, everything works fine.
But, if App.xaml isn't opened the changes aren't saved. I went through the code, it still goes through it like it should, it adds the attributes like it should, it even executes the line of code that's supposed to save the changes, except... changes aren't saved Frown | :(

This is an overview of what i do:

<br />
codeState.editPoint.StartOfDocument();<br />
string xmlText = codeState.editPoint.GetText(codeState.textDoc.EndPoint);<br />
<br />
--- add a couple of attributes using XmlDocuments<br />
--- save the changes into a memory stream<br />
<br />
codeState.editPoint.ReplaceText(codeState.textDoc.EndPoint, reader.ReadToEnd(), 0);<br />

Any ideas why?

I think, you must ask at WPF forum.

It's not really a WPF issue. The file just happens to be xaml, the problem would persist no matter the file type.
I thought of asking this in the Visual Studio forum, since I am working on a Visual Studio add-on... but, that's more of a "using" forum, than programming.

XElement vs XmlWriter Question

Hi all,

I am trying to make use of XElement instead of XmlWriter, but I am experiencing some hickups ... Sigh | :sigh:

The XmlWriter code works perfectly .. here it is:

// write the controller element and attributes
foreach (var controller in ControllerList)
{
    w.WriteStartElement("controller");
    w.WriteAttributeString("name", controller.Value.ControllerName);
    w.WriteAttributeString("description", controller.Value.ControllerDescription);
    w.WriteAttributeString("area", controller.Value.ControllerArea);
    w.WriteAttributeString("startdate", DateTimeClass.DateTimeYearMonthDay(controller.Value.StartDate));
    w.WriteAttributeString("enddate", DateTimeClass.DateTimeYearMonthDay(controller.Value.EndDate));
    w.WriteAttributeString("updatemode", controller.Value.UpdateMode);

    // write the reader element and attributes
    foreach (var reader in controller.Value.ReaderList)
    {
        w.WriteStartElement("reader");
        w.WriteAttributeString("name", reader.Value.ReaderName);
        w.WriteAttributeString("readergroup", reader.Value.ReaderGroup);
        w.WriteAttributeString("host", reader.Value.ReaderHost);
        w.WriteAttributeString("type", reader.Value.ReaderType);
        w.WriteAttributeString("startdate", DateTimeClass.DateTimeYearMonthDay(reader.Value.StartDate));
        w.WriteAttributeString("enddate", DateTimeClass.DateTimeYearMonthDay(reader.Value.EndDate));
        w.WriteAttributeString("description", reader.Value.ReaderDescription);
        // end the reader element
        w.WriteEndElement();
    }
    // end the controller element
    w.WriteEndElement();
}

-- XmlWriter Output --

but the XElement code does not produce the same results .. It appends the data to the first controller node OMG | :OMG:

... here is the code:

foreach (var controller in ControllerList)
{
    xElement.Element("plant").Element("building").Add(new XComment(String.Format("Controller: {0} Declaration", controller.Key)));
    xElement.Element("plant").Element("building").Add(new XElement("controller",
        new XAttribute("name", controller.Value.ControllerName),
        new XAttribute("description", controller.Value.ControllerDescription),
        new XAttribute("area", controller.Value.ControllerArea),
        new XAttribute("startdate", DateTimeClass.DateTimeYearMonthDay(controller.Value.StartDate)),
        new XAttribute("enddate", DateTimeClass.DateTimeYearMonthDay(controller.Value.EndDate)),
        new XAttribute("updatemode", controller.Value.UpdateMode)
        ));
    // write the reader element and attributes
    foreach (var reader in controller.Value.ReaderList)
    {
        xElement.Element("plant").Element("building").Element("controller").Add(new XElement("reader",
            new XAttribute("name", reader.Value.ReaderName),
            new XAttribute("readergroup", reader.Value.ReaderGroup),
            new XAttribute("host", reader.Value.ReaderHost),
            new XAttribute("type", reader.Value.ReaderType),
            new XAttribute("startdate", DateTimeClass.DateTimeYearMonthDay(reader.Value.StartDate)),
            new XAttribute("enddate", DateTimeClass.DateTimeYearMonthDay(reader.Value.EndDate)),
            new XAttribute("description", reader.Value.ReaderDescription)

    }
}

xElement.Element("plant").Element("building") is returning the 1st building tag in the XML. Similarly xElement.Element("plant").Element("building").Element("controller") returns the 1st controller, so all readers will be added to the first controller element in the XML.

You will be better off creating the controller element in the foreach (var controller in ControllerList) loop, adding it to the building. Adding the reader elements to the controller element you have just created inside the foreach (var reader in controller.Value.ReaderList) should fix your problem.

No probs. You should also find that, by creating the elements in the loop, you will be able to Factor out somthing like MakeControllerElement and MakeReaderElement methods. This will help the readability / maintainability of the code (always a problem when creating classes to build XML in my experience).

How about:

            new XAttribute("readergroup", reader.ReaderGroup),

            new XAttribute("description", reader.ReaderDescription));
}

XElement CreateControllerElement(ControllerType controller)
{
    new XElement("controller",
                new XAttribute("name", controller.ControllerName),
                new XAttribute("description", controller.ControllerDescription),

                new XAttribute("enddate", DateTimeClass.DateTimeYearMonthDay(controller.EndDate)),
                new XAttribute("updatemode", controller.UpdateMode));
}
        
void AddComment(XElement target, string format, params object[] args)
{
    target.Add(new XComment(String.Format(format, args)));
}

void Foo(string[] args)
{
    //...    
    XElement xElement;
    foreach (var controller in ControllerList)
    {                
        AddComment(xElement.Element("plant").Element("building"), "Controller: {0} Declaration", controller.Key);
        XElement con = CreateControllerElement(controller.Value);
        // write the reader element and attributes
        foreach (var reader in controller.Value.ReaderList)
            con.Add(CreateReaderElement(reader.Value));
        xElement.Element("plant").Element("building").Add(con);

    //...
}

Where the italicised stuff are types / method names I can't determine.
