How can i set the default value of my variable stored in session or viewstate before the first call
My code is:
public
class xxxxxxxxxxxxx: System.Web.UI.UserControl{
public
xxxxxxxxxxxxxxxxx(){
}
public xxxxxxxxxxxxxx(string user, Connection connection...)
{
}
...public
string User{ get{
return (string)Session["User"];}
set{
Session["User"] =
value;}
}
...
private
void Page_Load(object sender, System.EventArgs e)...
protected
override void OnLoad(EventArgs e)...
}
Explain better: from my app i want create this object without using the constructor with parameters, but the noparameters one. In this case i want a default user.
How can i do it Where must i write the assignment of default value
Thx
Session or viewstate, default value

Then you should do this:
public class xxxxxxxxxxxxx: System.Web.UI.UserControl{
{
private string _myString;
private int _myInt;
public xxxxxxxxxxxxxxxxx()
{
// Put your defaul initialization values here.
_myString = "Default string";
_myInt = 0;
}
public xxxxxxxxxxxxxx(string user, Connection connection...)
{
}
public string User
{
get
{
return (string)Session["User"];
}
set
{
Session["User"] = value;
}
}
}

In web user control:
public
GridLines VisibleGrid{
get{
return (GridLines) ViewState["VisibleGrid"];}
set{
ViewState["VisibleGrid"] =
value;DataGrid1.GridLines =
value;}
}
protected
override void OnLoad(EventArgs e){
base.OnLoad (e); if (Page.IsPostBack){
return;}
InizializzaComponente();
}
private
void InizializzaComponente(){
VisibleGrid = GridLines.None;}
______________________________________
In my form (web application)
if i set
myWebUserControl.VisibleGrid = GridLines.Vertical;
it doesn't work!!!
JA
Ok, i solved in this way (from your code)
private bool _Flag = true;
public bool Flag
{ get{ _Flag = (bool) ViewState["Flag"];
return _Flag;
}
set{
_Flag = value;
ViewState ["Flag"] = _Flag;
}
}
in init or onload method:
ViewState["Flag"] = _Flag;
