Dear sir/madam
I have designed a login page where a user can enter,user name and password.The program can compare the password from database and can verify.The program is ok for a single user.
But when we have multiple user then i got the problem.The problem is that how can we know the specific user have logged in by comparing the password with database.And after comparing the password,how can we generate the name of the user stored in database in a new page..

waiting for the reply..

You can add a column to your database telling you a user is currently logged in.

Store it in the session.

I'd recommend buying a book on ASP.NET and web development.

I would recommend you buy a book on ASP.NET and read it. If you're doing paid work, stop it, and you should be ashamed. If you're teaching yourself, you should slow down and work through a book rather than try to do something that you could only do very badly given your obvious lack of experience. You need to learn how to do it first, even if your code works, I expect it's far from production quality at this point.

Grid view?

Hi, In my project i used a gridview. I fill the details using Databind() method. And i want to format some detail using Html coding of the Grid view. They r working.

But during Runtime, the Datas are displayed twice both from html coding and Databind() method. How to avoid this?

I want to display only from Html coding? Is there is any code to fetch datas from Html?

Christian Graus2-Mar-09 21:13

2-Mar-09 21:13

Your best bet nearly always is using databinding. You can use runat="server" to interact with html elements, but I doubt that's what you want to do.

Perhaps if you posted your code we could point out what's wrong with it.

In C# i write this code for produce datas?

protected void lnkview_Click(object sender, EventArgs e)
{
view.Visible = true;
add.Visible = false;
try
{
con.Open();
com = new SqlCommand("select *from hotjob", con);
rd = com.ExecuteReader();
view1.DataSource = rd;
view1.DataBind();
con.Close();
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
}

But i want some of the datas to appear in Link button. So i format it in the Html Coding.

<asp:gridview id="view1" runat="server" cellpadding="4" forecolor="#333333" gridlines="None" xmlns:asp="#unknown">
<footerstyle backcolor="#507CD1" font-bold="True" forecolor="White">

<headerstyle backcolor="#507CD1" font-bold="True" forecolor="White">
<alternatingrowstyle backcolor="White">
<columns> <asp:templatefield headertext="Job-ID" headerstyle-horizontalalign="Center">

<asp:label id="lblId" runat="server" text="<%# Bind(" jid")="" %>"="">

<asp:templatefield headertext="Title" headerstyle-horizontalalign="Center">

<itemtemplate>
<asp:label id="lbltit" runat="server" text="<%# Bind(" title")="" %>"="">

<asp:templatefield headertext="Description" headerstyle-horizontalalign="Center">

<itemtemplate>
<asp:label id="lbldes" runat="server" text="<%# Bind(" description")="" %>"="">

<asp:templatefield headertext="Qualification" headerstyle-horizontalalign="Center">

<itemtemplate>
<asp:label id="lblqua" runat="server" text="<%# Bind(" qualification")="" %>"="">

<asp:templatefield headertext="Vacancies" headerstyle-horizontalalign="Center">

<itemtemplate>
<asp:label id="lblvac" runat="server" text="<%# Bind(" vac")="" %>"="">

<asp:templatefield headertext="Location" headerstyle-horizontalalign="Center">

<itemtemplate>
<asp:label id="lblloc" runat="server" text="<%# Bind(" location")="" %>"="">

<asp:templatefield headertext="Mail-ID" headerstyle-horizontalalign="Center">

<itemtemplate>
<asp:linkbutton id="lblmail" runat="server" text="<%# Bind(" mail")="" %>"="">

<asp:commandfield headertext="Delete" showdeletebutton="True" showheader="True">

This is the full code. It is working but datas display twice. I want to display only the Datas from Html.

Ah - add AutoGenerateColumns="false" to your grid view, by default it adds your templated columns AND generates one for each column in your data source.
