InfoPath Dev

 Hi Guys,

 I would like to ask your help to this scenario below (InfoPath and SharePoint 2013):

  - I have a SharePoint Library with (xml) items created by a InfoPath form (to simplify my explanation I will call this form as "A"). In this library there is some fields explicit (I've had to promote some InfoPath fields to SharePoint columns).

 - So, to consult this data, I developed a second  InfoPath form (I will call this form as "B"). In this second form I created a data connection to return all data from the library responsible to storage all xml files created by the form "A".  Into the form "B" I configure the data connection results to been shown as a repeating table.

- This form "B" is configured to be shown in a custom Web Part that I customized:

****************************************************** 

using Microsoft.Office.InfoPath.Server.Controls;
using System.Text; 

// XmlFormView control object to render the browser-enabled InfoPath form.
private XmlFormView xmlFormView = null;

// Field to hold the return value from the modal dialog box.
private TextBox hiddenText = null;
private string receivedValue = null;

// Property to store the InfoPath XSN URL.
[WebBrowsable(true)]
[WebDisplayName("Form XSN URL")]
[Description("Relative URL of the InfoPath XSN file.")]
[Category("Configurations")]
[Personalizable(PersonalizationScope.Shared)]
public string FormXSNURL { get; set; }

protected override void CreateChildControls()
{
    try
    {
        base.CreateChildControls();

        // Instantiate the XMlFormView object.
        this.xmlFormView = new XmlFormView();

        // Set the editing status to init on initial load.
        this.xmlFormView.EditingStatus = XmlFormView.EditingState.Init;

        // Add to the Web Part controls collection.
        this.Controls.Add(this.xmlFormView);

        this.hiddenText = new TextBox();

        // Hide the text box.
        this.hiddenText.Style.Add("display", "none");
        this.hiddenText.Style.Add("visibility", "hidden");

       // Assign a dummy class to the control so it can be found through jQuery functions.
        this.hiddenText.CssClass = "webparthiddenfield";

        // Add to the Web Part controls collection.
        this.Controls.Add(this.hiddenText);
    }
    catch
    {
        throw;
    }
}
 

protected override void OnPreRender(EventArgs e)
{
    try
    {
        // Determine whether the user has set the FormXSNURL property with InfoPath XSN location.
        if (!string.IsNullOrEmpty(this.FormXSNURL))
        {
            // Configure the XmlFormView control to host the form.
            this.xmlFormView.XsnLocation = this.FormXSNURL;

            // Set the editing status to ensure the control displays the form.
            this.xmlFormView.EditingStatus = XmlFormView.EditingState.Editing;
        }
    }
    catch
    {
        throw;
    }
}

******************************************************

- I add this web part in a SharePoint Web Part Page, for all users access the consult screen.

- So, until here, everything works fine. The problem is (my help request):
 
One of these fields returned by the data connection that I created into the form "B" is the url link responsible to open the form "A" with all xml data loaded. I added a button into the repeating table (I added a column and configured a image button). The objective is use this button to call the Form "A" InfoPath link to be load in a modal dialog (It could be loaded with the SharePoint 2013 native modal). So, I need a code snippet to get the current url of the row and a code snippet to load this url in a modal.

I am try something like this:

http://msdn.microsoft.com/en-us/library/office/hh278954(v=office.14).aspx 

and this code (into the button that I configured into the repeating table):

******************* 

 public void CTRL462_5_Clicked(object sender, ClickedEventArgs e)
        {                       
            string XmlLocation = e.Source.SelectSingleNode("/dfs:myFields/dfs:dataFields/d:SharePointListItem_RW/d:XmlLocation", this.NamespaceManager).Value;
            HttpContext.Current.Response.Redirect("http:/mysitecollectionurl/subsite/_layouts/15/FormServer.aspx?XMLLocation=" + XmlLocation + "&ClientInstalled=true&DefaultItemOpen=1&Source=http://mysitecollection/subsite/pagetoconsultitemsofformA.aspx", false);
        }

******************** 

I know that this scenario is specific and is rare to use infopath like a Form consult (generally this is developed in pure .net) but i really need configure this scenário. So i will be really grateful with some help. 

Could somebody, please, help me with this scenário?
