How to find controls value inside static method

Question

Inside static method am notable to get hidden field values:

private static void GetDetails()
{
    Page page = (Page)HttpContext.Current.Handler;
    HiddenField hdnUserID = (HiddenField)page.FindControl("hdnUserID");
    txtAccreditation.Text = hdnUserID.Value ; //  here hdnUserID.Value is null why ?? 
}

try like this

  Page page = (Page)HttpContext.Current.Handler;
  TextBox TextBox1 = (TextBox)page.FindControl("TextBox1");

  TextBox TextBox2 = (TextBox)page.FindControl("TextBox2");

perhaps you need to change your code to something like this:

Change your code as followed

private static void GetDetails(HiddenField field)
{     
   txtAccreditation.Text = field.Value ;
}

and call it like this

Page page = (Page)HttpContext.Current.Handler;
HiddenField hdnUserID = (HiddenField)page.FindControl("hdnUserID");
YourClassName.GetDetails(hdnUserId);

What I do not understand is why would you call it through a static operation.

I would assume you create something more like the following code:

private static string GetDetails(HiddenField field)
{     
   return field.Value ;
}

This would result in the following code: This code will not be present inside the static function.

Page page = (Page)HttpContext.Current.Handler;
HiddenField hdnUserID = (HiddenField)page.FindControl("hdnUserID");
txtAccreditation.Text = YourClassName.GetDetails(hdnUserId);

meaning you could actually use the code everywhere else
