Say there is a TextBox on an ASP.NET page
<asp:TextBox id="DateTextBox" runat="server" />
with some value set in the code-behind.
How to access that value from another class of C# code-file through HttpContext or any other way?
You can access a property in you page via HttpContext
even from a static method.
in your page:
public string DateTextBoxText
{
get{ return this.DateTextBox.Text; }
set{ this.DateTextBox.Text = value; }
}
somewhere else(even in a different dll):
public class Data
{
public static string GetData()
{
TypeOfYourPage page = HttpContext.Current.Handler as TypeOfYourPage;
if (page != null)
{
return page.DateTextBoxText;
//btw, what a strange method!
}
return null;
}
}
Note that this works only if it's called from within a lifecycle of this page.
It's normally better to use ViewState
or Session
to maintain variables across postback. Or just use the property above directly when you have a reference to this page.
