Page.Context Property

.NET Framework 2.0

Other Versions

Gets the HttpContext object associated with the page.

Namespace: System.Web.UI
Assembly: System.Web (in system.web.dll)

Syntax

C++

Copy

protected internal override HttpContext Context { get; }

Copy

/** @property */
protected HttpContext get_Context ()

JScript

Copy

protected internal override function get Context () : HttpContext

Property Value

An HttpContext object that contains information associated with the current page.

Remarks

This property provides programmatic access to the context the page runs in, including information about the request, response, session, and application.

Example

The following code example uses the Context property to access the HttpContext.AddError and HttpContext.ClearError methods and the HttpContext.AllErrors property. The example creates three custom exceptions using the AddError method and uses the AllErrors property to load these exceptions to an array. It then writes the array to the containing page and uses the ClearError method to clear all the errors from the Context property.

Copy


void Page_Load(Object sender,EventArgs e) 
{
   Response.Write("<h3>Page.Context Example:</h3>");

   // Add three custom exceptions.
   Context.AddError(new Exception("<font color='red'><h3>New Exception #1.</h3>"));
   Context.AddError(new Exception("<font color='red'><h3>New Exception #2.</h3>"));
   Context.AddError(new Exception("<font color='red'><h3>New Exception #3.</h3>"));
 
   // Capture all the new Exceptions in an array.
   Exception[] errs = Context.AllErrors;
 
   foreach (Exception ex in errs)
   {
      Response.Write("<center><b>" + Server.HtmlEncode(ex.ToString()) + "</b></center><br>"); 
   }
 
   // Clear the exceptions so ASP.NET won't handle them.
   Context.ClearError();
}

Copy

void Page_Load(Object sender,System.EventArgs e) 
{
    get_Response().Write("<h3>Page.Context Example:</h3>");

    // Add three custom exceptions.
    get_Context().AddError(new Exception
        ("<font color='red'><h3>New Exception #1.</h3>"));
    get_Context().AddError(new Exception
        ("<font color='red'><h3>New Exception #2.</h3>"));
    get_Context().AddError(new Exception
        ("<font color='red'><h3>New Exception #3.</h3>"));
 
    // Capture all the new Exceptions in an array.
    System.Exception errs[] = get_Context().get_AllErrors();
 
    for (int iCtr=0;iCtr<errs.length;iCtr++) {
        System.Exception ex = errs[iCtr];
        get_Response().Write("<center><b>" 
            + get_Server().HtmlEncode(ex.ToString())
            +"</b></center><br>");
    }
    // Clear the exceptions so ASP.NET won't handle them.
    get_Context().ClearError();
}//Page_Load
