Re: how to get the count - ASP.NET Discussion Boards

hi....

Thank you for helping me..

yah i too got the count but i am getting the count after clicking

the button submit in my page.

I wrote the code in Checkbox1_ChechedChanged.

I took the count into the label.

plz tell me where i am missing...

Thanks in advance

ya you miss AutoPostBack="True"

if you give AutoPostBack="True" only it will fire the Checkbox1_ChechedChanged event.

var Counter;

window.onload = function()
{
TotalChkBx = parseInt('<%= this.GridView1.Rows.Count %>');
Counter = 0;
}

function SelectAll(CheckBox)
{
var TargetBaseControl = document.getElementById('<%= this.GridView1.ClientID %>');
var TargetChildControl = "CheckBox1";
var Inputs = TargetBaseControl.getElementsByTagName("input");
for(var n = 0; n < Inputs.length; ++n)
if(Inputs[n].type == 'checkbox' && Inputs[n].id.indexOf(TargetChildControl,0) >= 0)
Inputs[n].checked = CheckBox.checked;
Counter = CheckBox.checked ? TotalChkBx : 0;
if(Counter !=0)
document.getElementById('Label1').innerText = Counter;
else
document.getElementById('Label1').innerText = "no records selected";
}

//in your aspx
<headertemplate>
<asp:checkbox id="CheckBox2" runat="server" onclick="javascript:SelectAll(this);">

//your aspx.cs page

hi..
I am working on stocks manageent.I want updated price of shares.I am using rss feed.I have use grid view to make rss.But problem is i am not able to decode thhis xml rss.
Plz help how i cause rss to show updated stocks price.
here is code that i try-

protected void Page_Load(object sender, EventArgs e)
{

}
protected void Button1_Click(object sender, EventArgs e)
{
XmlTextReader reader = new XmlTextReader("http://blogs.ibibo.com/sharetipsfree/feed/rss");
DataSet dataset = new DataSet();
dataset.ReadXml(reader);
GridView1.DataSource = dataset.Tables[2];
GridView1.DataBind();
}

The RSS that you have mentioned is about some definations.

However the above code is to read the XML and display same on the page.

But if you want your code to display the updated pricing, then the rss xml must be updated after some interval of time.

If you can do the same, only then report will display the updated values

If rss is taken from-
"http://www.moneycontrol.com/stocks/marketstats/mostactive.php?optex=NSE&index=31&opttopic=mostactive[^]"

then how will i extract the data??

Hi
The above link is not providing any rss.
If the same is rss then the link should be giving some xml file.

The link is accepting some query string arguments, reading and displaying the same on scree.

You cannot do any thing with this.
Search for RSS for the same

CommandArgument='<%# Bind("ID")>' is it possible to send id&name within the same command argument

//use like this
'<%# "Redirect.aspx?id=" + DataBinder.Eval(Container.DataItem,"ID")+ "&name=" + DataBinder.Eval(Container.DataItem,"name")%>'
