Your going to have to use Javascript, and create your sort of fake grid, and update that fake grid in the DOM. At the same time the item is added, you need to use a web service to update the cart with that item. So when you do a postback, all the items can repopulate that same space.

.It should happen without postback

Update panels do a partial postback of the page, but it's still a postback.

The only way to get around a postback is to use a web service in the background, in combination with Javascript, to just keep manipulating the dom, until you leave the page.

As far as manipulating the Gridview in JavaScript, I have no idea how.

That's alot of work for that feature or confirmation.

Dropdownlist selected item text couldnt save into database

I am using dropdownlist in c# asp.net. Here one dropdown list getting data's from database and its having required field validator also.,
My ASP design coding is.,

<asp:dropdownlist id="zonename" runat="server" width="195px" tooltip="Select Zone">
<asp:requiredfieldvalidator id="RequiredFieldValidator1" runat="server" controltovalidate="zonename" errormessage="Zone Name Required" initialvalue="Select Zone">
And MY C# coding is....,

da = new MySqlDataAdapter("select name from zone", mysqlcon);
dt = new DataTable();
da.Fill(dt);
zonename.Items.Clear();
zonename.Items.Add("Select Zone");

for (int i = 0; i <= dt.Rows.Count - 1; i++)
{
zonename.Items.Add(dt.Rows[i]["name"].ToString());
}
mysqlcon.Close();

WHEN I AM SAVING THIS DROPDOWNLIST TEXT TO THE DATABASE.,THE WORD "Select Zone" ONLY GOING TO THE DATABASE.

MY INSERT QUERY IS.,

"insert into TABLENAME(zonename) values('"+zonename.text+"')";

Here i couldnt understand what is going on.,i need to save the selected text to the database. If anybody know how to solve this problem, Please let me know.,

Thanks.,

zonename looks like it is some sort of list so it is unlikely to have a member called text. It would also help if you formatted your code and put <pre> tags around it, to make it more readable thus:

da = new MySqlDataAdapter("select name from zone", mysqlcon);
dt = new DataTable();
da.Fill(dt);
zonename.Items.Clear();
zonename.Items.Add("Select Zone");

for (int i = 0; i <= dt.Rows.Count - 1; i++)
{
    zonename.Items.Add(dt.Rows[i]["name"].ToString());
} 
mysqlcon.Close();

One of these days I'm going to think of a really clever signature.

Look at the SelectedText and SelectedValue properties of the DropDownList control.

it's

ddl.items.clear();
ddl.items.add(new listitem("Select a Zone", "--")
ddl.items.add(new listitem(Name, Value));

'Check that the selection is not "--" or > 0
string pvalue = ddl.selectedvalue;
insert into table pvalue

and get the selected value of the ddl, not the selected text

Classic ASP - Prevent Cache from being stored

Hi everyone

Please find below the exact code you need in order to prevent cache from being stored. I am posting this in order to help everyone that ever needs it as I spent myself some hours this last saturday trying to do it. I saw many combinations from the same code everywhere in several forums but this is the only one that worked for me comes, as referenced below

After filling a form, then going back to the previous page and then forward back again, the form is empty as expected. Nothing is stored in the browser's cache

Hope it helps

Alas, it'll be hard to find on the forum, as new messages keep coming in. You might want to submit it as a trick; makes it a bit easier to find.

The word "article" implies a longer text with explanation, while a "tip/trick" entry is usually a short description of a solution. Both are available under the same link. This way, the articles all meet certain minimal quality-criteria. A tip/trick would also need some background on why you wrote it, and what problem it solves.

Aah, all registered users have the option to vote on an article, or on tips. If you meet a lot resistance, it might be better to give it a rest for a moment - it's no fun if you get a lot of hard words for one's work. Still, if you ask Sandeep how it should be formatted/worded before it's approved as a "trick" would probably give you a list of tips on the subject.

Hi,

I have developed an application using DOTNET and Oracle 11g, The application while performing load test it throws an error as seen below

"Message: Exception Message : ORA-12542: TNS:address already in use Exception : at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, OpoSqlValCtx* pOpoSqlValCtx, Object src, String procedure)
at Oracle.DataAccess.Client.OracleException.HandleError(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, Object src)at Oracle.DataAccess.Client.OracleConnection.Open()
"

The same code works well in regulat cases and breaks only during load testing when the users are 100+ accessing at the same time..Any suggestions are appreciated.

Thanks & Regards,

you need to add command event handler for this:
try this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class dynamicimage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string str = @"<asp:ImageButton ID=""dynoimage"" ImageUrl=""~/images/about01.jpg"" runat=""server"" oncommand=""clickme"" commandname=""btn"" />";
        Control c = ParseControl(str);
        form1.Controls.Add(c);
        ((ImageButton)Page.FindControl("dynoimage")).Command += new CommandEventHandler(clickme);
    }

    protected void clickme(object sender,CommandEventArgs e)
    {
        Response.Write("Image clicked");
        Label1.Text = "Image clicked";
    }
}

and here is the aspx page:

IsMobile not determining mobile!

Jassim Rahma26-Oct-12 8:42

I am using this code to determine if the device is mobile:

XML

<asp:TableRow>
    <asp:TableCell VerticalAlign="Top">is Mobile</asp:TableCell>
    <asp:TableCell VerticalAlign="Top">:</asp:TableCell>
    <asp:TableCell VerticalAlign="Top"><% Response.Write(Request.Browser.IsMobileDevice); %></asp:TableCell>
</asp:TableRow>

but I always get IsMobile = False when using my Samsung Galaxy SII or S3!

why is that? can you try it here from mobile and let me know if you'll get IsMobile = True?

Those don't work very good,

Like is robot, the searchbot detector.

I think it's uses a formula to determine the device or to detect a bot. But over time, things change, and it's hard to keep that up to date.

So figure out a different way to do it.

Looks like you may half to start collecting user agent values, and do a compare or regex against them.

Hi,

I have the following SPF record in my host:

what's your advise?

-all

means that if none of the rules are ok, don't accept the email.
This will mess up your ability to send mail to all domains.

~all
means that if none of the rules are ok, do a soft error

@ 86400 IN TXT "v=spf1 ip4:192.1468.1.1/24 ~mx ~a ~all"

Means any server in the ip range of 192.168.1.1 to 192.168.1.254 can send mail, softerror if no mx record of mail server, softerror of no A PTR, softerror for all other.

If you have a small block of public ip's, then you need to use a caluclator to figure out the subnet.

taking the time to write your SPF file will tighten up your mail security, maybe reduce spam or impersonators.

just remember "-" is reject, "~" is softerror

This is a better reference to how it works, than the other above
