ExtJS: Stream OpenXML document to new window

[jpooley]

I will be using OpenXML to generate Powerpoint Presentations based on "scores" data POSTed in some way from an Ext.gridPanel (which I have got to work)

I am using an MVC C# FileResult to generate my presentation:

[HttpPost]
public FileResult Report(GridScores scores)
{
// OpenXml code would go here but I am returning a demo PPT file as a proof of concept to make this example shorter
// return GeneratePresentation(scores);
return File(@"C:\Temp\Demo.ppt", "application/vnd.ms-powerpoint", "NewFile.ppt");
}

I have a button on the gridPanels TBar. What ExtJS/Javascript code should I use to:

• Open the the presentation in a new window?
• Present the user with a Download dialog to download the file?

You can use a Form object and specify a target in the submit method, as shown below.

someRenderedForm.submit({
  url: 'someUrl',
  params: {
      someRequestParam: someValue
  },
  method: 'POST',
  target: 'powerPointWindow'
});

Thanks for this, I am so close, I just can't seem to to post the data for the grid successfully.

I have tried:

        var encodedData = Ext.encode(Ext.pluck(grid.getStore().data.items, 'data'));
        var form = new Ext.form.Panel();
                form.submit({
                    url: '/mycontroller/report',
                    params: encodedData,
                    jsonSubmit: true,
                    method: 'POST',
                    target: '_blank'
                });

and also

        var encodedData = Ext.encode(Ext.pluck(grid.getStore().data.items, 'data'));
        var form = new Ext.form.Panel();
                form.submit({
                    url: '/mycontroller/report',
                    params: {scores: encodedData},
                    jsonSubmit: true,
                    method: 'POST',
                    target: '_blank'
                });

But my data is not read into MVC action.

Can you see what I am doing wrong?
