HiddenField hide = (HiddenField)ucFormWizard.FindControl("Hidden1");
hide.Value = status;

ascx page:

JavaScript

<asp:HiddenField ID="Hidden1" runat="server" />
function GetSlnForm() {
      var slnFormValue = document.getElementById('<%=Hidden1.ClientID%>').value;
}

If you view the source of the page does your hidden field contain a value?

What's not working? Are you getting error? Is the value from your HiddenField empty? Please be more specific so we can easily help you out.

You should generally avoid using FindControl on a user control. Instead, add a public property to the .ascx.cs class, and set that property from the page class.

public class YourUserControl : UserControl
{
    public string Status
    {
        get { return Hidden1.Value; }
        set { Hidden1.Value = value; }
    }
    
    ...
}

string status = ucFormWizard.SaveDataToDB(commandData[1], Convert.ToInt32(commandData[2]), commandData[3], commandData[4], commandData[5]);
ucFormWizard.Status = status;
