Thanks for your reply

but how i could use select query in dataview?

i don't need to select top N rows when i am fetching the data from the database but at some point of time i need to select top N rows from dataview which contains all the data.

so is it possible to use select query in dataview?

Thanks,
Rachit Damani.

for this...you can loop thru the dataview to get the top n records
Or better: Add a column on the datatable, set it's autoincrement value, include it in
the rowfilter for the dataview

Hope you get the idea

<code>
<body>
<form id="form1" runat="server">

<asp:ListBox ID="ListBox1" runat="server"></asp:ListBox>
</form>
<script>
var listBox = document.getElementById( '<%= ListBox1.ClientID %>' );
alert(listBox.length);
listBox.options[0] = new Option("Hello");
alert(listBox.length);
</script>
</body>
</code>

Like this.......

Note that there is no ADD item as such that work cross browser, you have to get the number of items currently there and then add new ones by changing the index (the options[indexnumber] above).

Hi,

I have a frameset(in default.aspx) with two vertical panes. In the left pane i have added "default1.aspx" and in the right pane i have added "default2.aspx". It works fine with the following code..

<frameset cols="*,*" frameborder="NO" border="0" framespacing="0">

<frame src="default1.aspx" name="leftFrame" scrolling="no" style="border:1px solid #99ABBD" >

<frame src="default2.aspx" name="rightFrame" scrolling="no" style="border:1px solid #99ABBD" >

</frameset>

I was trying to close the window(frameset) with the following code

Window.close();

But it doesn't works, can anyone tell me how to close a window(with frameset) programatically.

Thanking you

Sebastian

Hi,
First of all, JavaScript is case sensitive, therefore - window.close();
Second, you can close only the window you opened from the code. Otherwise, you will be asked to confirm the action (IE) or will be ignored (FF 2.0). There is a trick to avoid the confimation in IE:

...
window.opener = self;
window.close();

but it seems to me that in IE 7.0 it does not work anymore (not sure).

If you are in a frame you can refer to the topmost window (the window that contains the frameset) via top property:
window.top.close();

It would not be an ExecuteNonQuery, that is more for update or insert statements, a command that does not return data.

Try reseaching the ExecuteReader method
