Hi
I have the following code and why can't i change the value of myvar in the
DataGrid1_editc ommand event so that the (changed) value of myvar is there in
the Update event?? (it fires i debugged it!):
namespace MYproject
{
using System;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.UI.W ebControls;
using System.Web.UI.H tmlControls;
public class MyUsercontrol: System.Web.UI.U serControl
{
public string myvar ="hello";
private void Page_Load(objec t sender, System.EventArg s e)
{
}
public void DataGrid1_EditC ommand(object source,
System.Web.UI.W ebControls.Data GridCommandEven tArgs e)
{
myvar ="goodbye"; //enters this code first
}
private void DataGrid1_Updat eCommand(object source,
System.Web.UI.W ebControls.Data GridCommandEven tArgs e)
{
string temp; // enters this code next!!!
temp = myvar; // myvar = "hello" ???? instead of the wanted "goodbye"
}
}
}

The variable value will be lost between postbacks. If it need to be
persisted it should be saved to teh view state by the control and got back
when a postback occurs.

Hi,
You could simply save it in a session as
Session("myvar" ) = myvar;
later you retrieve it using
myvar = Session("myvar" ).ToString();
Please note that you should make sure that you saved the variable before
retrieve , usually you do so in the onload event checking for the IsPostBack
property.
cheers,

Do you know whether ANSI C (or some other dialects) support the
