Ok, so I assume that this will only be available in the future. In the meantime, I need to be able to give my user the report in some format. How can I do this? Can I print it?... Can I make it PDF? Or can I only make a screen-dump? If this can not be printed, it is really not worth that much...

Hi,

That is basically our full code, but I had to "clean" it when sharing because we use some internal libraries that I can't share.

Trying to address your errors:

1) DS is the FlatDatasource from where you are populating your PivotGrid

Dim ds As FlatDataSource

2) The function that can be shown as errors to you are Imports

<Runtime.InteropServices.DllImport("user32.dll")>
Private Shared Function SetForegroundWindow(hWnd As IntPtr) As <Runtime.InteropServices.MarshalAs(Runtime.InteropServices.UnmanagedType.Bool)> Boolean
End Function

<Runtime.InteropServices.DllImport("user32.dll", SetLastError:=True)>
Private Shared Function FindWindow(lpClassName As String, lpWindowName As String) As System.IntPtr
End Function

Hope it helps,

Eduardo Peccorini

Thanks for the post.

I tried your attached code but its getting some errors. like ds. and some functions.

Could you please share your exporting full code.

I submitted the "New Idea" for "Excel Export" on Infragistics ideas site more than a year ago and it is still "Waiting for Votes" even when it was the most voted on WinForms for some time, let’s face it, it's not a "New Idea" it's basic functionality and Infragistics should have developed this on their own with the release or immediately after releasing the WinPivotGrid control, they just don't care about WinForms anymore.

So, after the painful wait of over a year I decided that it shouldn't be so complicated to figure out how to do it myself even when not having access to all the internal properties that Infragistics has on their own code (for them should be even easier), so I sat down a Saturday and by Sunday it was working really good (wife was not happy, but I was :)). After some time in beta testing and some production tests it is now working ok, fast and stable enough that I can deploy it to my customers. I'm sure that all the smart devs here will find some things to improve, since I'm not really familiar with Excel Interops, and I will be really happy if they point them out and the code gets improved.

I want to share this with everyone here as a way of repaying all the help that you get when someone shares his work online and you find a way to do what you need fast and easy, it has really helped me before, and I hope it saves some time for others.

Of course this code was created taking bits of code and ideas from several sources on Internet, all the credit goes to the different devs that published their findings. I took the time to clean up the code that we use to leave just the relevant parts and translate it (we speak Spanish, sorry for my English by the way), so if there are errors is because I made a typo while translating, please point them and I will correct them for the next one.

Let's get to how to do it, take into account that we use FlatDataSource as the data source for our WinPivotGrid, of course if you are using anything else you will have to adapt. Also as you can imagine the resulting Excel PivotTable does not look exactly the same as your report but is close and it will let you work with it.

1) The main problem to create the Export yourself is that Infragistics never introduced the ability to iterate over currently selected RowHeaders, ColumnHeaders and Measures, so there is no way for you to recreate the Pivot in Excel as is on the WinPivot because you don't know what the user has selected. Well, to be able to save and load a report as the user built-it Michael DiFilippo from Infragistics suggested to me to handle the following events (Thank God the guys from Infragistics in the Forums and handling Support Cases are always really nice, take the time to help and really know their stuff):
AxisAddHierarchyAsyncCompleted
AxisRemoveHierarchyAsyncCompleted
AddFilterAsyncCompleted
RemoveFilterAsyncCompleted
AddMeasureAsyncCompleted
RemoveMeasureAsyncCompleted

These events let you know when a RowHeader, ColumnHeader, Filter or Measure is being added or removed so you can keep track of the user selection reflecting the changes in your own lists. You can check this on the related post: http://ko.infragistics.com/community/forums/t/93336.aspx

2) Once you have that working, firstly make sure that you have Microsoft Office Interops installed and referenced in your project, then you just need to use Interops to create an Excel Book, transfer the data to one sheet, create a PivotTable pointing to that data and use your lists to populate the Pivot's Rows, Columns and Measures. Sounds easy right :). Attached is a text file with the code, some prerequisites/clarifications:

a) “ds” is the FlatDataSource that you are using for your WinPivotGrid (i.e. Dim ds As FlatDataSource.

b) “Rows”, “Cols” and “Measures” are the lists (List(Of String)) that hold the RowHeaders, ColumnHeaders and Measures that the user selected.
Dim Rows As New List(Of String)
Dim Cols As New List(Of String)
Dim Measures As New List(Of String)

c) The FlatDataSource must have at least 1 item (ds.ItemSource(0))

Regards,

I have also been waiting for a solution and been contacting the infragistics helpdesk a few times in regards to this features as well as others such as:

expand all columns/rows, columns/rows sorting, layout saving

Unfortunately their standard answer is always ask you to look at their ideas site to show you the ideas are already included and will be available in the "future".

For excel export, if you already have data binding to your data collection, you could do what I did by adding a copy contextmenu, and then structure your data collection into "," delimiter and put into clipboard. this way at least I allow user to paste it to excel.

Now, nearly a half year later my question: when will this idea be implemented?

Do you have a timeline?

Best regards,
