Hi Sammy78,

This scenario is possible. Here is an example:
If we assume that this is the HTML representation of field:

<input type="hidden" id="myHiddenField" value="MyValue" />

The easiest way to get the value is to find the HtmlHiddenElement in the page by its id and extract its value. To do this follow this steps:
1. Convert a click step to code
2. Change the code from this:

// Click 'HtmlTag'

Pages.HttpLocalhost9000HtmlHid.HtmlTag.Click(false);

to this:

[CodedStep(@"GetValue 'myHiddenField'")]

public void HiddenField_CodedStep()

{

//Get Hidden field by id

var hiddenFieldControl = Pages.HttpLocalhost9000HtmlHid.Get<HtmlInputHidden>("id=myHiddenField");

var fieldValue = hiddenFieldControl.Value;

}

Please note that "HttpLocalhost9000HtmlHid" is the page that is currently in use in my test yours will be different. If that page does not contain the hidden element the test step will fail.

Hi Nikolai,
I was finally able to try out your solution, but my test can't seem to find the hiddenField, but it might have to do with the page definition. Here is the code for the aspx:

<asp:Content ID="Content2" ContentPlaceHolderID="cphContenuPage" runat="server">

<div class="grid_24">

<div class="clear"></div>

<div class="grid_24 H1TitrePage">

<asp:Label ID="lblTitreH1" runat="server" Text="lblTitreH1"></asp:Label>

<asp:Image ID="imgBandeau" runat="server" CssClass="ccImage" />

<asp:Image ID="imgDestination" runat="server" CssClass="ccImage" />

</div>

<div class="clear"></div>

<telerik:radscriptmanager ID="RadScriptManager1" runat="server">

</telerik:radscriptmanager>

<h2 id="h2Titre" runat="server">Partez l'esprit tranquille !</h2>

<br />

<h5 id="lblPolice" runat="server">NO de Police</h5>

<asp:Label ID="lblNoPoliceCache" runat="server" Text="Label" Visible="False"></asp:Label>

<asp:HiddenField ID="hfNoPolice" runat="server" />

<uc1:ProtectionsAssures ID="ProtectionsAssures1" runat="server" />

<uc2:GrilleRecommandation ID="GrilleRecommandation1" runat="server" />

<br />

<table style="width: 900px;">

<tr>

<td width="80%">

</td>

<td align="right" valign="top" width="15%">

<asp:Button ID="btnRetournerQuoter" runat="server" Width="150px" />

</td>

</tr>

</table>

</div>

</asp:Content>

And here's the code the I put in the coded_step:

<CodedStep("Click 'Div'")> _

Public Sub HiddenField_CodedStep()

'Get Hidden field by id

Dim hiddenFieldControl As HtmlInputHidden = Pages.Page_confirmation.Get(Of HtmlInputHidden)("id=hfNoPolice")

Dim fieldValue As String = hiddenFieldControl.Value

Log.WriteLine("Value: " + fieldValue)

End Sub

And my log doesn't write.
Thanks for the help

Sam

Hello Sammy78,

From the page you've sent I don't see a Value attribute for you "hfNoPolice" field. This hidden field has only two attributes - id and name:
Server:

<asp:HiddenField ID="hfNoPolice" runat="server" />

Rendered Client Html:

<input type="hidden" name="hfNoPolice" id="hfNoPolice" />

so it is normal the value to be 'null'. May be there is a server or client method for setting the value that is not part of the code you sent?
Anyway I added a 'Value' attribute to your code:

<asp:HiddenField ID="hfNoPolice" runat="server" Value="myCustomValue" />

and the test returned the value as it should.(see attachment)

All the best,
