Hi,
First make the AutoPostBack property to true. And for the RadioButtonList1_SelectedIndexChanged event you can access it as follows.
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
Response.Write(RadioButtonList1.SelectedValue);
}
Here im just writing the selected value to the web page,for an example.
Thx,
Gayani

Hi,
I have a code in the login.aspx.vb that create a cache item with the information of the user.
When the cache item expired it make a CallBack. In the callback I want to sign out and
redirect to the login page. When it tries to redirect, I received an "Object reference not set
to an instance of an object." error because the System.Web.HttpContext.Current = nothing.
Here is the code in the login page code behind:
Private Sub MyCacheItemRemovedCallback(ByVal key As String, ByVal val As Object, ByVal reason As Caching.CacheItemRemovedReason)
If reason = Caching.CacheItemRemovedReason.Expired Then
Try
System.Web.HttpContext.Current.Response.Redirect("SignOut.aspx")
Catch ex As Exception
End Try
End If
End Sub
Private Function AlreadyLogin() As Boolean
Dim sKey As String = TextBox_Login.Text.Trim + TextBox_Password.Text.Trim
Dim sUser As String = Cache(sKey)
If (sUser = Nothing) Or (sUser = "") Then
Dim callBack As Caching.CacheItemRemovedCallback = New Caching.CacheItemRemovedCallback(AddressOf MyCacheItemRemovedCallback)
Dim SessTimeOut As TimeSpan = New TimeSpan(0, 0, 15, , 0)
HttpContext.Current.Cache.Insert(sKey, sKey, Nothing, DateTime.MaxValue, SessTimeOut, System.Web.Caching.CacheItemPriority.NotRemovable, callBack)
Session("CurrentUser") = TextBox_Login.Text.Trim + TextBox_Password.Text.Trim
Return False
Else
Label_ErrorMessage.Text = Constants.ERROR_LOGIN_USER_LOGGED_IN
Return True
End If
End Function
Thank you for your responses

This method will fire when the item is removed from the cache, but there wont be any request from the user at that time, it just like if you try to redirect the user to some place when the session times out, (the user couldnt know that)
You need to ask when the user the requests a page if the control is from the cache, if not, you redirect to login page

Can you put an example on how to do this?
Also, there's a way to redirect to a page in this scenario?
Thanks

You can do something very similar to what you got here
Private Function AlreadyLogin() As Boolean
Dim sKey As String = TextBox_Login.Text.Trim + TextBox_Password.Text.Trim
Dim sUser As String = Cache(sKey)
If (sUser = Nothing) Or (sUser = "") Then
Dim callBack As Caching.CacheItemRemovedCallback = New Caching.CacheItemRemovedCallback(AddressOf MyCacheItemRemovedCallback)
Dim SessTimeOut As TimeSpan = New TimeSpan(0, 0, 15, , 0)
HttpContext.Current.Cache.Insert(sKey, sKey, Nothing, DateTime.MaxValue, SessTimeOut, System.Web.Caching.CacheItemPriority.NotRemovable, callBack)
Session("CurrentUser") = TextBox_Login.Text.Trim + TextBox_Password.Text.Trim
Return False
Else
Label_ErrorMessage.Text = Constants.ERROR_LOGIN_USER_LOGGED_IN
Return True
End If
End Function
If the first time you add something to the session, and session timeout is longer than the cache timeout, then when the cache value is nothing and session isnot nothing then it means that the cache item expired, there you can redirect the user to the login page with FormsAuthentication.RedirectToLoginPage or response.redirect("yourloginpage.aspx") or server.transfer

I am using a FormView in my website. Everything is working fine but I want to know how to get the value of label4 in the code behind. The Label4 is bound to data in a SQL database. This label is located within the EDIT TEMPLATE in the formview..
How come everything in a formview is not able to be accessed programmicially?

It is, but you have to use the formview.findcontrol ("controlname") and cast it to the appropiate type

|

Sweet! Thanks!
Are you talking about (Label)FormView1.FindControl("Label4").Text ?
Something like that?
|
|
|
|
|
Yes
Does it work?
Alexei Rodriguez
|
|
|
|
|
Sure does!
Label newLabel = (Label)FormView1.FindControl("Label4");
Thanks again!

I have a website which deals with the registration for users, while the an independent C# class which is used to interact through a small client.Is there anyway i can start this class along with webpages in the asp.net hosting, and that it can run all time like a service ?
|
|
|
|
|
Hi,
Just a suggestion.Why not you write that class in a web service and mark those methods as WebMethods. And configure the web service with your asp.net application. Then at the time you want, you may call the service and perform the required tasks.
FYI:
Here is a guide to create web services

Hope this helps you.

I used to be able to double-click on a control, and it would add a method to the .vb file.
Now, it changes to Source view mode of the .aspx file, and adds a block with the method inside.
How do I change it back?
<div class="ForumSig">"Neque porro quisquam est qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit..."
"There is no one who loves pain itself, who seeks after it and wants to have it, simply because it is pain..."
</div>
|
|
|
|
|
I think you are using HTML controls ... 
|
|
|
|
|
<%@ Page Language="vb" AutoEventWireup="true" CodeBehind="Page3.aspx.vb" Inherits="ApplicationForm.Page31" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs)
End Sub
</script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Software Install</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
<asp:CheckBox ID="CheckBox1" runat="server" OnCheckedChanged="CheckBox1_CheckedChanged" /></div>
</form>
</body>
</html>
I did see what you were referring to in the help, though.
"Neque porro quisquam est qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit..."
"There is no one who loves pain itself, who seeks after it and wants to have it, simply because it is pain..."
