Response is not available in this context

[Joe Stateson]

I added a gridview print routine to my dotnet 2 app. It works fine after
googling why it didnt work for an hour or more.
Since I got several grids on various pages I thought I would add it to my
"constant class" which all my codebehinds have and I put all my common code
in it.

namespace Training
{
..
public class ConstClass
{
...
public void print(GridView gv, strFilename)
{
Response.Clear();
..etc..
}
...
}
}
the above would not compile until I added System.Web.UI.Page as in

public class ConstClass : System.Web.UI.Page


ok, it finally recognized "Response" and compiled. Unfortunately, it wont
run and gives me the error message "Response is not available in this
context"

There is something wrong with how I defined my class I suspect. All I
wanted to do was to call the "print" function from any of my pages and not
have to put the print function in each C# page. I am doing something wrong,
yet all my other functions get called and work ok (they do not have
"response").


I call the print function as outlined below
=======
protected void Page_Load(object sender, EventArgs e)
{
if (null == Session["cUsefulFunctions"])
Session["cUsefulFunctions"] = new ConstClass(Session);
cUsefulFunctions = (ConstClass)Session["cUsefulFunctions"];
..etc..

protected void btnPrint_Click(object sender, EventArgs e)
{
cUsefulFunctions.print(gv4needed, "needed.xls");
}

You will have to use HTTPContext.Response property to do that.

Your class must be under APP_Code as I can guess, that is why response is
not available.

You don't need to inherit from System.Web.UI.Page. Hope that helps.
