I recently accepted the challenge to raise funds to support the JDRF Northwest - Nordstrom Beat the Bridge in its efforts to find a cure for diabetes and it's deadly complications.  Every day 35 more children are diagnosed with diabetes. This diagnosis means a lifetime of insulin shots and extremely devastating complications, not to mention the fact that diabetes on average shortens a person's lifespan by 15 years and the only hope is a cure. The Juvenile Diabetes Research Foundation (JDRF) is the largest private funder of diabetes research in the world and since it was founded in 1970, has awarded over $900 million to diabetes research.  JDRF has implemented a campaign to raise $1 billion over the next five years in order to accelerate the cure for diabetes.

Last year's Beat the Bridge event raised a record $1,000,000 for diabetes research. This year, our goal is to BEAT $1,130,000 for research!  On May 20 the Nordstrom Beat the Bridge to Beat Diabetes run and walk to benefit the Juvenile Diabetes Research Foundation will take place.  I will be there because I want to find a cure for diabetes for the 21 million Americans who have to live with this disease.   

Please help support me in this important fundraising event by contributing generously to the JDRF Northwest - Nordstrom Beat the Bridge. Your tax-deductible contribution will fund the world's leading diabetes research aimed at finding a cure. It is faster and easier than ever to support this great cause - you can make your donation online by simply clicking on the link at the bottom of this message. If you would prefer, you can also send your tax-deductible contribution to the address listed below. More information on the JDRF Northwest - Nordstrom Beat the Bridge and its programs can be found at beatthebridge.org.  

Whatever you can give will help.  It all adds up! I greatly appreciate your support and will keep you posted on my progress.

Sincerely,

Summary: Optimize version 1 of the Excel Services programmability framework to extend Microsoft Office Excel 2007 and Excel Services functionalities to work with SharePoint lists, query tables on Excel Services, external workbook references, SQL write-back, and user-defined functions (UDFs).

Link: https://msdn2.microsoft.com/en-us/library/bb267252.aspx

NOTE: I already caught a few mistakes that the editing process introduced (like the one in the summary about working with UDFs being an "extension")... but the content should still be intact :o)... I'll go over it and make some requests to clean it up when I get a chance.

NOTE 2: I just found out that the article isn't supposed to be published yet, hence the mistakes I've been catching.  The article that's live is a Draft copy... we're just going to leave it up and replace it with the final version once that's ready which should only take a few days.

Here is a simple way of enabling paging, without having to modify any existing UDF code (you could also use this same code as part of a helper function, though you'd need to add the page/rows parameters to your UDF signature).

To use it in your workbook just wrap the call to the UDF with the pagination UDF.  So when before you might have had as your array formula:

{=getBDCData("SharedServices1", "AdventureWorksDWInstance", "Product")}

Now you use:

{=paginate(getBDCData("SharedServices1", "AdventureWorksDWInstance", "Product"), 50, 1)} 

Note: As you'll notice this is far from the most efficient/performant way of doing this! But it is the easiest and only one that doesn't require modifying the original UDFs. If you have time, you should consider building the pagination into the UDFs themselves, so you only query the data source for the rows you are going to display instead of grabbing every row and later determining the ones you care about.

/// <summary>

/// Paginate the data in the object array passed in

/// </summary>

/// <param name="data">Object[,] with original data</param>

/// <param name="rows">Number of rows per page</param>

/// <param name="page">Current page number</param>

/// <returns></returns>

 [UdfMethod(IsVolatile = true)]

public object[,] paginate(object[,] data, int rows, int page)

{

    if ((data == null)||(data.Rank != 2))

        return data;

    object[,] results = new object[rows, data.GetLength(1)];

    for (int i = (page - 1) * rows;

         (i < (page * rows)) && (i < data.GetLength(0));

         i++)

    {

        for (int j = 0; j < data.GetLength(1); j++)

        {

            results[i - ((page - 1) * rows), j] = data[i, j];

        }

    }

    return results;

}

The BDC is brand new with SharePoint 2007, and is not yet fully integrated into Excel and Excel Services... though, if you've read one or two other entries in this blog you've probably figured out where I'm going with this :o)

Here's a pretty simple UDF that will take a BDC instance name, entity name, and will return the data associated with it.

Without further delay... just call the UDF below in an array formula in your workbook as usual (e.g. "{=getBDCData("SharedServices1", "AdventureWorksDWInstance", "Product")}")

PreReq: I used the Adventure Works DW BDC sample from https://msdn2.microsoft.com/en-us/library/ms494876.aspx ... you'll need to set up the BDC yourself as well to use this UDF.

PS: Sorry about the horrible formatting... It's a pain refactoring to get the code to look half-way decent on this blog.

/// <summary>

/// Gets data from the entity of the specified BDC instance.

/// </summary>
