InfoPath Dynamic Hyperlink Field C# and Code Behind

Posted on by

In InfoPath, dynamically update a hyperlink field using code.
Sounded simple, but it took me a few minutes to get it straightened out.

I’ve attached the InfoPath form and the code behind files here: http://www.sharepointed.com/wp-content/uploads/2012/12/Dynamic_URL1.zip

Create a new Blank InfoPath form.

Add a Hyperlink control to the form.

In this step, I’ve set the field to Read-Only. Why? I didn’t want the user to be able to modify the field.

Change the field names. The first field (field1) is the field that will hold the URL path. The second field (field2) will hold the text that you want to display in place of the URL.

I’ve updated my fields as follows:
field1 changed to URLpath
field2 changed to URLdisplay

To quickly test this post, click on the Developer tab, then click Loading Event.

        public void FormEvents_Loading(object sender, LoadingEventArgs e)
        {
            XPathNavigator ipFormNav = MainDataSource.CreateNavigator();
            XPathNavigator assnAttachURL = ipFormNav.SelectSingleNode("/my:myFields/my:URLpath", NamespaceManager);
            XPathNavigator assnAttachDisplay = ipFormNav.SelectSingleNode("/my:myFields/my:URLpath/@my:URLdisplay", NamespaceManager);

            //Update the URL path to a document on your site.
            assnAttachURL.SetValue("http://sharepointed.com/library/taco.xlsx");
            assnAttachDisplay.SetValue("taco");
        }

To get the correct XPath values, see the screenshot below.

To see this work, in the code editor, click on Build, then Start Debugging.

Replace Hyperlink column with a Button

If you have ever had to deal with unruly hyperlink columns in a List, you know they can be a mess.  What I’ve done is add a button to a column using SharePoint Designer. Then set the buttons path equal to the unruly hyperlink url.

To start this example I created a List then added a Hyperlink column named LongURL.

From the Ribbon click on Edit List to open SharePoint Designer.

Once SharePoint Designer opens, click on All Items in the Views section.

In this step we are going to add a column to the table in the Web Part.  I right clicked in the LongURL column, selected Insert, then Column to the Right.

With the cursor in the row of the new column, click on the Design tab at the top of screen, click on Insert Control, then Form Action Button.

Next we will want to set two of the buttons properties.  Click on the button, the Tag Properties for the button should now be displayed on the right side of SharePoint Designer.  In the Attributes section, you can set the text that appears on the button.  This can be static text or text that is bound to an item in the row.

While still in the Tag Properties, scroll down to Events and look for onclick, this is where we are setting the hyperlink value of the button.   In the onclick field enter:  window.location.href='{@LongURL}’

Now, click save and return to your browser and refresh the page.  You should now see the newly added button.

Safe to assume you want to remove the LongURL column?  Go back to SharePoint Designer.  Click in the column that displays LongURL.  Now, right click, select Delete, then Delete Columns.  Click save, and return to your browser and refresh the page.

Your page should now look like this:
