Hello,
I am using VS 2005
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager id="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel id="UpdatePanel1" runat="server" EnableViewState="False">
<contenttemplate>
<asp:TextBox ID="TextBox1" runat="server" Style="position: relative; top: 0px;"></asp:TextBox><br />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click1" Style="position: relative"
Text="Next" />
<asp:Button ID="Button2" runat="server" Style="position: relative" Text="Pevious" OnClick="Button2_Click" />
<asp:Button ID="Button3" runat="server" Style="left: 0px; position: relative" Text="Update" OnClick="Button3_Click" /><br />
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>" SelectCommand='SELECT * FROM "EMP"'>
</asp:SqlDataSource>
</contenttemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button3" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
And in the aspx.vb file i have code following:
Protected Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
MessageBox.Show(TextBox1.Text, "xx", MessageBoxButtons.OK, MessageBoxIcon.Information, MessageBoxDefaultButton.Button1, MessageBoxOptions.DefaultDesktopOnly)
End Sub
but it is not showing me the current value (user chaged the value; when page comes on the browser) of the textbox; it is showing me the value which was at the time of page load.
After searching a lot on the net, i am posting the question here, to get the solution how to get the current/changed value of the textbox which is in the update panel; on click of the button.
Thanks & Regards

plz check whether you have checked the page load in your page load event....
code in c#:
if (!IsPostBack)
{
//Code
}

in the page load event i have following code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Page.IsPostBack = False Then
Session("r") = 0
End If
'dv.Table.Rows(1)(1) = "xx"
showdata()
End Sub

try to put the showdata() inside the post back. that is the error...
code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Page.IsPostBack = False Then
Session("r") = 0
'dv.Table.Rows(1)(1) = "xx"
showdata()
End If
End Sub

Thanks a lot padmanabhan N. It is working fine; but it is really new to me how it is working now; when page's postback event has been fired and i have following in showdata:
Public Sub showdata()
dv = CType(SqlDataSource1.Select(DataSourceSelectArguments.Empty), System.Data.DataView)
TextBox1.Text = dv.Table.Rows(Session("r"))(1).ToString()
End Sub
what is the relation with the postback's true/false?
I wish to thanks for providing the the answer and shall be more informative for the question i asked above please.
Best Regards

with pleasure,
The postback is doing all the things. The loop your write inside the postback will fire only when the page is loaded and the value will be maintained and the loop wont be executed after that. So, if we write the code after the loop will be fired in even and every postback. just keep the breakpoint in the page load and check. You can see for each and every postback the pageload event is fired.
So each and every time the button click it fires the page load first and then the button event. So, the showdata() will clears your modification and the original data will be set. For this only you got the old values.
I hope you understand now.

Please don't involve god for all these pity matters. You are capable enough to handle this all by your own.
nofear5535 wrote: i must create the table in the sql database accordingly 2 satisfy these conditns...
There can be many options. I would create tables like : UserDetails, UserRoles, RolePermissions
UserRole
UserID
UserName
FirstName
LastName
...
UserRoles
UserID
RoleID
RolePermissions
RoleID
PermissionType
This is just an example, but you may come up with your design too. ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Use ASP.Net's login control (or have your own textboxes and labels) and ADO.Net to validate the UserID and password.
nofear5535 wrote: enable the alter option according 2 the user logged
Your database must have a table that relates each user to a role. Now each role will have certain rights (updating data in your case) in the application. When the user logs in, check the role and grant the rights that the role has.(Enabling disabling the update link or whatever you use).
There are plenty of articles on net that implement this kind of thing.

Ok, let me make it more simple for you.
1.) Create a table(UserDetails) something like this
UserID
UserName
Password
IsAdmin
2.) Create a Stored Procedure with parameters username, password
Select * from UserDetails Where UserName = @UserName and Password = @Password
3.) Call this stored procedure from your C# code.
4.) Check if the result contains any row. If it does than the user has been authenticated[^].
5.) If the user has been authenticated, check if he is authorised for Administrator persmission. You will do this by checking the value of IsAdmin.
Well, this is the maxmimum I can do.
And I again suggest you to buy a book on C# and start reading. You may also look at some of the starter article at CP.

Is this homework ? Talk to your teacher, they should know you are this lost. Is it paid work ? What a disgrace, if permissions are in the hands of someone who has not the first clue how to impliment them.

Hello.
I have an aspx page with a literal thet I'm building a table inside it.
the table rows come from db with an id num in each row.
Now, I want to add a button to each row that in his click will run a function with the id.
How can I add a button that on his click will run a server side function with the id?
Thanks.

Create the object of button class and set the relevant properties as you do in the markup. Also handle the click event for it. Then you can place it in the page(or any other container) using Controls.Add method.

So, what you have tried for this? Create object of the button , assign unique ID , add event handler with the button and add them inside the table row.
