GridView row data Shown in FormView. Change Mode & Save data

Question

 

Hello,

 

    In ASP.NET WebForms app, I have a Gridview whose data is shown in From View when a row is selected from the GridView. I have New, Save, Edit & Cancel buttons outside Grid & Form View's. 

 

    My FormView in aspx :

 

<asp:FormView ID="inqFormView" runat="server" DataKeyNames="Id"

ItemType="VincitoreCRMApplication.Models.Inquiry" DefaultMode="ReadOnly"

Width="100%" Height="206px" CssClass="panel panel-default"

style="background-color: white; border-radius:8px; margin-top:-1px;"

OnModeChanging="inqFormView_ModeChanging" >

I am facing couple of problems & queries regarding the buttons & actions on Form View : 

1. In my editBtn, I change the Mode of FormView to Edit, but it is not changing  - it remains in ItemTemplate only. MY code of editBtn :

protected void editInquiryBtn_Click(object sender, EventArgs e)

{

newInquiry.Visible = false;

editInquiry.Visible = false;

saveInquiry.Visible = true;

cancelBtn.Visible = true;

TaskTitle = "Update Inquiry Details";

//Tried to set item to be edited in FormView 

inqFormView_GetItem(5);

inqFormView.ChangeMode(FormViewMode.Edit);

// inqFormView.DataBind();   // IF I ENABLE THIS LINE, THEN NO DATA IS SHOWN

saveInquiry.CommandArgument = EditArgs;

return;

}

• Once able to edit, user clicks o the "Save" btn (that is outside of Grid & Form Views')  I want to someway fire the Update call of FormView & the data gets updated.
• I have an EmptyDataTemplate in FromView, with just empty text boxes. When their is no data, the FromView is just hidden (not visible). I want the form to be seen when when their is no data. For this, in Page_Load, in is(! IsPostback ) , I am calling 
  inqFormView_GetItem(-1);
  public Inquiry inqFormView_GetItem(int id)

  {

  // If their i no item of the id passed, adds an empty item and sends it. But it doesn't work

  Inquiry item = new Inquiry();

  item.Id = 0;

  List<Inquiry> items = _db.Inquiries.Where(s => s.Id == id).ToList<Inquiry>();

  if (items.Count > 0)

  {

  item = items[0];

  }

  else

  items.Add(item);

  return item;

  }
   
   For ModeChanging, I added the event also, but that is never fired at all :
  protected void inqFormView_ModeChanging(object sender, FormViewModeEventArgs e)

  {

  inqFormView.ChangeMode(e.NewMode);

  inqFormView.DataBind();

  }

   
  Can you please help me with these problems and guide me achieve the goal.
  Any help is highly appreciated.
   
  Thanks.
