How To : Calculate Median Value Using InfoPath Forms

Thanks To Entan Ming!!

I was going crazy for this untill Entan Ming provided a solution to me.

I wanted to calculate Median for values entered into my InfoPath form (as of now I have provided 10 textboxes in InfoPath but you can modify my code as per your requirement)

Though I have provided 10 textboxes, users can enter less than 10 values as well and I need to count Median for it.

Yes, I know that we can achieve this simply by creating a List with one calculated column and can use =MEDIAN() formula (as simple as that)

But when users want to see the final Median value before submitting the values (for whatsoever reason), you can’t use List!!

So, Let’s start!!

First of all (if you are not aware of how to do it), check out my post on How To : Code in InfoPath Forms 2010

Once you know what I am talking about (for this perticular code), create 11 textboxes and 1 button and call below method on button click:


public void sorting()


int[] arry = new int[11];
int counter = 0;

for (int i = 1; i <= 10; i++)
if (MainDataSource.CreateNavigator().SelectSingleNode(“/my:myFields/my:field” + i + “”, NamespaceManager).Value != “”)
arry[i] = Convert.ToInt32(MainDataSource.CreateNavigator().SelectSingleNode(“/my:myFields/my:field” + i + “”, NamespaceManager).Value);

int[] resul = new int[counter];
for (int i = 0; i < counter; i++)
resul[i] = arry[i + 1];

bool sortnum = true;

int pos = 0;

int tot = counter;

int median = 0;

while (sortnum == true)

for (int j = (pos + 1); j < tot; j++)

int rd = resul[pos];

int fg = resul[j];

if (rd > fg)

resul[pos] = fg;

resul[j] = rd;



pos = pos + 1;

if (pos >= tot)

sortnum = false;



if (tot % 2 == 0)

int sdd = resul[(tot / 2) – 1] + resul[tot / 2] / 2;

median = sdd;



median = resul[(tot – 1) / 2];


string a = Convert.ToString(median);

XPathNavigator P2 = this.MainDataSource.CreateNavigator().SelectSingleNode(“//my:myFields/my:field11”, this.NamespaceManager);

P2.SetValue(((Convert.ToDouble(resul[(tot/2)-1]) + Convert.ToDouble(resul[(tot / 2)])) / 2).ToString());


You will get Median value (at run time) in your field11 textbox!! 🙂

How To : Code in InfoPath Forms 2010

Hey Folks,

Le’ts learn little bit of InfoPath today!! 🙂

I will post the basic steps to learn InfoPath later, but today I am going to show how you can Code in InfoPath.

Before we start, make sure you have installed the prerequisites:

1.  Microsoft InfoPath 2010

2.  Microsoft Visual Studio 2010

3.  Visual Studio Tools for Applications (VSTA)

So Let’s Start:

Open up InfoPath 2010 (Hope you know how to do it!! 😛 )

Go To File -> New -> Select Blank Form

Your new Blank Form will look like below, check out the demo as shown below:

Change the lable to This is a “Hellow World” InfoPath Form and add a Button control to the form:

Your form will now look like this:

Now Select Develop Tab and click on Language:

Select Category as Programming (if not selected) and choose your preferred programming language:

Click OK and close the form.

Now click on Code Editor Button in the Ribbon.

If your prerequisites were installed correctly, InfoPath forms designer will now open Visual Studio Tools for Applications and create a event handler for the button click event.

public void CTRL1_5_Clicked(object sender, ClickedEventArgs e)

Add your custom code inside this event.

public void CTRL1_5_Clicked(object sender, ClickedEventArgs e)


    XPathNavigator domNav = MainDataSource.CreateNavigator();
    XPathNavigator field = domNav.SelectSingleNode(“/my:myFields/my:field1”, NamespaceManager);
    field.SetValue(“Hello World”);


Build your code and save the project.

Return to the InfoPath Forms Designer.

On the Home pane in the ribbon you will see on the far right the form preview command.

Click on this command to preview your form.
