Hi! How can I check if current user has submitted an XForm in Page_Load event? I wan't to show the statistics control instead of the XForm when the user aleady has answered a question. /Jonas

Hi Jonas! You could use the XFormData's HasAlreadyPosted method. Something like this in the pagetemplate code:


  
  protected void override OnInit(EventArgs ea)
  {
    if( myXFormControl.Data.HasAlreadyPosted( this ))
    {
      // switch to statistics view
    }
  }

When i try this, XFormControl is always null in OnInit event. Code in front (user control): Code behind:


override protected void OnInit(EventArgs e)
{
	PropertyXForm form = XFormProperty.InnerProperty as PropertyXForm;
               if (form.XFormControl.Data.HasAlreadyPosted(this.Page))

Hi Jonas! The problem is that the contained XFormControl wont be available until CreateChildControls() has been called. But, there is another way of getting the XFormData, you could use an explicit call to CreateFormData(). Note, that in order for HasAlreadPosted() to work, you must specify the ChannelOption.DataBase first. This would normally be done on the Submit button click. Check out the below code, it should work in the OnInit():



  EPiServer.Core.PropertyXForm propXForm = XFormProperty.InnerProperty as EPiServer.Core.PropertyXForm;

  EPiServer.XForms.XFormData formData = propXForm.Form.CreateFormData();
  formData.ChannelOptions = EPiServer.XForms.ChannelOptions.Database;
        
  if(formData.HasAlreadyPosted( this.Page ))
  {
      Response.Write( "already voted" );
  }
