Cascading update in Infopath form using XML data

We often come across with the requirement to do dynamic update. Since SharePoint is new. I worked a lot on finding this solution. Here we go simple steps for this….

Step one:

Create a XML file like in this format …

               

<?xml version="1.0" encoding="UTF-8"?>

<Data>

                <Country value="India">

                                <State value="Tamil Nadu"/>

                                <State value="Andhra Pradesh"/>

                                <State value="Kerala"/>

                </Country>

                <Country value="Srilanka">

                                <State value="Western Province"/>

                                <State value="Eastern Province"/>

                </Country>

</Data>

                               

                               

 Step 2:

Open InfoPath form and create the Country and State dropdown list boxes.

Step 3:

Add the xml data which we created from the InfoPath form.

Step 4:

Give the xml data name and click finish …

Step 5:

Right click list box of country and go to properties

Step 6:

Select the xml data source and Select the Country as value.

Step 7:

Similarly go to state properties and click to add the xml data and filter data to country ….

Step 8:

And now click preview to see the changes…
