Hi,
I was try to convert xml to mpp, it works. But it always show only few columns once open mpp, and I wanne show other columns , how should i do??

btw, I was used property ‘AppendNewValues’ , but it doesnt work.

this is my code:

        Project project = new Project(@"C:\Code\Data\Test-F.xml");

        var attr = ExtendedAttributeDefinition.CreateTaskDefinition(CustomFieldType.Text, ExtendedAttributeTask.Text1, "Custom Field");
        attr.AppendNewValues = true;
        project.ExtendedAttributes.Add(attr);
         
        var task = project.RootTask.Children.Add("Task");

        var attribute = attr.CreateExtendedAttribute("ContextContextContext");
        foreach (var item in project.RootTask.Children)
        {
            item.ExtendedAttributes.Add(attribute);
        }
          

        project.Save($@"C:\Code\Data\Text-F{DateTime.Now.ToString("yyyyMMddHHmmss")}.mpp", SaveFileFormat.Mpp);

@Jiangqiming,

since you`re opening file from XML view info (View, Table, Filters, etc) is missing in the project.
You can use the following trick to add the column:

Project project = new Project("input.xml");
project.Save("output.mpp"); // View data (project.View, project.Tables, etc) is populated by default values when project is first saved to MPP format.

var attr = ExtendedAttributeDefinition.CreateTaskDefinition(CustomFieldType.Text, ExtendedAttributeTask.Text1, "Custom Field");
project.ExtendedAttributes.Add(attr);

foreach (var item in project.RootTask.Children)
{
    var attribute = attr.CreateExtendedAttribute("Test value");
    item.ExtendedAttributes.Add(attribute);
}

var table = project.Tables.FirstOrDefault(t => t.Name == "&Entry"); // Table of Gantt chart view which is displayed by default when MPP file is opened.

// Adding column
table.TableFields.Add(new TableField()
    {
        Field = Field.TaskText1,
        Title = "Task Text1",
        Width = 20
    });


project.Save(@"output.mpp", new MPPSaveOptions()
    {
        WriteViewData = true  // WriteViewData flag should be specified to save changes in TableFields.
    });

View data (project.View, project.Tables, etc) is populated by default values when project is first saved to MPP format.

We will improve this scenario to avoid double call of Save method.
