I write this code for showing totalprice in a gridview footer.when this page loaded user input his quantity on textboxes and press a button,after that must see the total price in gridview footer.here is my click event code:(but when I input something in m textboxes and press the button the total price in footer is 0)I used breakpoint and saw the qty is "".how should I correct my code?

protected void Button1_Click(object sender, EventArgs e)
    {
        if (GridView1.Rows.Count > 0)
        {
            for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
            {
                TextBox qty = (TextBox)GridView1.Rows[i].FindControl("textbox2");
                Label pr = (Label)GridView1.Rows[i].FindControl("label3");
                float total = 0;
                if (!string.IsNullOrEmpty(qty.Text))
                {
                    float qty1 = float.Parse(qty.Text);

                    float pr1 = float.Parse(pr.Text);
                    total = total + (qty1 * pr1);
                }
                Label t = (Label)GridView1.FooterRow.FindControl("label3");
                t.Text = total.ToString();
            }

Are you sure that exists control with name textbox2 in every row of gridview?

Did you try to specify cell,like this

<br />
TextBox qty = (TextBox)GridView1.Rows[i].Cells[1].FindControl("textbox2");

Instead index 1 of cell,set cell index which have value of textbox2.

Is textbox2 within template item?
Does textbox2 have values after Gridview1 is populated with data?

I have make a sample based on your code:

<br />
        string[] values ={"zero", "one", "two", "three" ,"four"};<br />
        GridView1.DataSource = values;<br />
        GridView1.DataBind();<br />
        <br />
         /*TextBox1 is within ItemTemplate of Gridview1*/<br />
        //add values on textbox1<br />
        for (int i = 0; i <= GridView1.Rows.Count - 1; i++)<br />
        {<br />
            TextBox qty = (TextBox)GridView1.Rows[i].FindControl("Textbox1");<br />
            qty.Text = i.ToString();<br />
        }<br />
<br />
        string resultvalues = "";<br />
        //read values from textbox1<br />
        for (int i = 0; i <= GridView1.Rows.Count - 1; i++)<br />
        {<br />
            TextBox qty = (TextBox)GridView1.Rows[i].FindControl("Textbox1");<br />
            resultvalues += qty.Text + ";";<br />
        }

and result of variable resultvalues is:0;1;2;3;4;

Hi,

Add the login userID's to a "loggedin" database table,
and check whether the current userID used to login
exists in the table.

For that to work, however, you need to insure that users
are recorded as logged out when they exit the application.

You can do that by checking if their sessions have expired,
and deleting the userID record from the table.

Linking the SessionID to the userID should be enough.

I hope this would be helpful.

We cant give you source code but we can advise you to start with a beginner article of how asp.net works. Why not try out Google, lots of articles there.
