Means ? It won't work until your session contains a valid DataTable object with rows.

but the code remains the same from the example on the website the only difference is i have incorporated a code behind file ? so i dont quite understand why it works when there is no code-behind ????

See this is not the matter you have code behind or not. I reiterate, it's the problem of session's NULL value. So check session is NULL before proceeding. By the way, where you are assigning value to the session ? I have seen you are assigning value to session after you refer it. To refer a value from session, it needs to be created before

can you show me please if possible ?
thank you
|

Well, you can check NULL in session like
if ( Session["cart"] != NULL )
else
It's a c# code, you can convert into VB.NET, Let me know if it helps

Is it possible to iterate through the items in a GridView using
JavaScript on the client?
Thanks
|

Well, a gridview does not exist on the client, it's a table. Yes, you can iterate over it.

Thanks Christian. When I try to do this, it says gridView does not exist.
Am I wrong here?
var Table = document.getElementById(gridViewId);
for(i=0; i< Table.rows.length; i++ )
{
}
I have gridView inside the Panel like below. Do you think it fails because Gridview is inside Panel and table?
<asp:Panel ID="PanelGrid" runat="server" Visible="true">
<table>
<tr> <td> <asp:GridView> </asp:GridView> </td> </tr>
</table>
</asp:Panel>
Thanks

It depends, what is gridViewId ? The id you assign on the server is not the one used on the client. You need to do something like
var gridViewId = '<%=gridview.ClientID%.';
to create the variable you use to find the element by it's id.

Use text or ntext data type for the field.

You are mistaken.
The limit for text is 2147483647 characters.
The limit for ntext is 1073741823 characters.

Kind of ironic, seeing as you didn't bother to check yourself before posting.

How can we fully disable the autocomplete feature of browsers for our site ? I mean how to prevent browsers from remembering textbox values.

When a .net web site starts up, does it load the web.config into memory and just refer to/use that copy, or does it always reload it from disk to retrieve the desired setting?

I believe it uses a file watcher to notice when the file is changed, and thus reload it.

This gets asked at least once a week. Your drop down is data bound, and you're binding to it in your page load. When you data bind, your selection is lost, as the old data is lost, even if it was the same. Put the code in a !IsPostback block so it only populates the first time the page loads.

you have to move a part of your code that initial your dropdownlist in page_load event of the page to a if block
if(!IsPostBack)
{
//your code...for initial of dropdownlist
}
