ViewState?

In the Page_Load method:

if (this.IsPostBack)
      Response.Output.Write (ViewState["Sql"]);
else
      ViewState["Sql"] = "test";

It works fine, no problems at all.

how about inside a class.cs after IsPostBack...?

How do you access the ViewState from your class.cs?

like this

string SQL;
SQL =(string)ViewState["GridSql"];

ViewState is not a part of your class, so you cannot access it like this. You have to assign it somehow

tks, avenger.. but somehow how?

I don't know. It is not possible to compile the solution if you have just calls to ViewState from a class. You can make it like this:

using System;
using System.Web.UI;
using System.Diagnostics;

class MyClass {
  public StateBag viewState = null;
  ...
  public void SomeMethod () {
    // Do something with the view state
    Trace.WriteLine (this.viewState["SQL"]);
  }
  ...
}

And in the Page_Load:
if (this.IsPostBack) {
    MyClass mc = new MyClass();
    mc.viewState = this.ViewState;
    mc.SomeMethod();
}
else
     ViewState["Sql"] = "test";

hello again Avenger, about this view state issue,

how come i do this on when i load my form ViewState["XMLFORM"] = XMLDocResult.InnerXml;

and on   override protected void OnInit(EventArgs e)
            {

                  InitializeComponent();

                  sSQL = (string)ViewState["XMLFORM"];  --> is null?

(not from inside a class, this is all on the code behnid of the same page)

yep, that was it... thanks a lot!
