Creating Powerpoint Table using ‘OpenXML’ with XAML Applications

I was recently struck with creating a Powerpoint presentation with a table in it using OpenXml, Googling did not help me a lot, so below is the solution.

I need to mention a thing here, I was struck ‘n’ number of times in between and a tool named ‘Open XML SDK 2.5 for Microsoft Office’ helped me solve the problems. I would seriously recommend this tool if you are trying to create your own structure using OpenXML. This accurately tells where the problem lies and what is expected and missing. (It isn't that easy to use this though!!!). It shows an XML node and you need to find that and add/remove as the tool tells.

You can download it from here.

Below, we will be able to see how to use OpenXml to create a Powerpoint presentation with table in it.

Hope you have prior knowledge of how to create a WCF service :0/ .

Kindly reference or add namespaces as below. You will also need to download OpenXml DLLs from Nuget.

using System.Linq;
using System.Runtime.Serialization;

The Configuration data contract is as shown below. I have 'display name' attribute associated to it so that I can show the same in my presentation Table header.

[DataContract]
    public class Configuration
    {
        [DataMember]
        [DisplayName("Value")]
        public string Value { get; set; }

        [DataMember]
        [DisplayName("Name")]
        public decimal Name{ get; set; }
    }

Now we will look at the client side:

You can now add the service reference (as you do normally) and write the below code.

ServiceClient proxy = new ServiceClient();
Stream stream;
SaveFileDialog objSFD;
private void btnPowerpoint_Click(object sender, RoutedEventArgs e)
{
     objSFD = new SaveFileDialog()
    {
        // DefaultExt = "csv",
        Filter = "Powerpoint Presentation (*.pptx)|*.pptx | All files (*.*)|*.*",
        FilterIndex = 1,

    };

    if ( objSFD.ShowDialog()==true)
    {
// Here Configuration is a class in the Service. Please look at service for more information
//about this class
        List<ServiceReference.Configuration>
        obj = new List<ServiceReference.Configuration>();

//Data can be anything which needs to go into ppt as table
        foreach (var config in Data)
        {
            obj.Add(new ServiceReference.Configuration()
            {
                Value = Data.Value,
                Name = Data.Name,
            });
        }

        proxy.CreateTableInLastSlideAsync
        (new System.Collections.ObjectModel.ObservableCollection<Configuration>(obj));
        proxy.CreateTableInLastSlideCompleted +=
        new EventHandler<CreateTableInLastSlideCompletedEventArgs>
            (proxy_CreateTableInLastSlideCompleted);
    }
}

void proxy_CreateTableInLastSlideCompleted
    (object sender, CreateTableInLastSlideCompletedEventArgs e)
{
    if (e.Result == null)
        return;

    using (System.IO.Stream stream = objSFD.OpenFile())
    {
        stream.Write(e.Result, 0, e.Result.Length);

    }
}

You will be able to see the output as below:
