i want to create table in runtime
actually in web page, user will select colors and each color have number of sizes.
now i want when user colors i have to create the textbox equal to its sizes.
suppose the user have select red color and red color have 2 sizes then the datatable will be like this:

_____________________________________
|color| 0 | 1 | 2 |
_____________________________________

|Red | Textbox | Textbox | Textbox |

in the above table 0,1,2 are sizes of red color

i hope you got my question

your basic issue is that anything you create after or during page load, won't have viewstate. What do you want to do with colors ?

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
}

Padmanabhan

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

Regards
Girish Sharma

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

Padmanabhan

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
Girish Sharma

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.

How did you tried to connect with DB? What problem are you getting ? You have to more clear and specific while asking question in the forum. Please read forum guidelines before post.

Please don't involve god for all these pity matters. You are capable enough to handle this all by your own.

nofear5535 wrote:

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]

Use ASP.Net's login control (or have your own textboxes and labels) and ADO.Net to validate the UserID and password.

nofear5535 wrote:

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. Rose | [Rose]
