Hi, How can I share in the eval? thanks.

How would you share with Eval ("column") / 3?

If the column value of 45 / 3, lists the value of 15,

Is it possible to share with the asp Eval ("column") / 3?

look at this example :

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:GridView ID="GridView1" runat="server">
        <Columns>
            <asp:TemplateField HeaderText="Some">
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text='<%# ((float.Parse(Eval("Even").ToString())) / 3).ToString("0.0") %>'></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
    <div>
    </div>
    </form>
</body>
</html>

code behind :

    protected void Page_Load(object sender, EventArgs e)
    {
        var some =from q in Enumerable.Range(1, 100).AsEnumerable ()
                  where  q % 2 == 0
                  select new
                  {
                      Even =q 
                  };
        

        GridView1.DataSource = some;
        GridView1.DataBind();
    }

Thank you it works.
Why, if the value is 0, displays such signs: NaN?
If the value is zero, the write 0.00.

hi

you get that becouse you divide by Zero so you can use something like this :

<asp:Label ID="Label3" runat="server" Text='<%#(int) Eval("Even") > 0 && (int)Eval("odd") > 0 ? ((double.Parse(Eval("Even").ToString())) / (double.Parse(Eval("odd").ToString()))).ToString("0.0"): "0.00" %>'></asp:Label>

also another way) you can check cell text in GridView RowDataBound Event and replaced with New Text.

thanks

Thanks, it works.

How about instead of three, I would like in the second column to calculate the value?

Something like:

Text='<%# Bind("CelaDnevnica", "{0:N} €" ) %>'></asp:Label>    (<asp:Label ID="Label90" runat="server" Text='<%# Eval("CelaDnevnicaStevilo") %>'></asp:Label>x<asp:Label ID="Label13" runat="server" Text='<%# ((float.Parse(Eval("CelaDnevnica").ToString())) / (float.Parse(Eval("Number).ToString()).ToString("0.0") %>'></asp:Label>€)

<asp:Label ID="Label3" runat="server" Text='<%# ((double.Parse(Eval("Even").ToString())) / (double.Parse(Eval("odd").ToString()))).ToString("0.0") %>'></asp:Label>
