Hi All,

In client server application, normally the client talks to the server and gets results.
I want to know how the server can talk back to the client - i know msmq
is one solution - but is there any other solution - how can my server application
can send its latest update to all its client that are connected to it.
say, update the client's user interface from time to time..is there any workaround related code that will keep track of the clients?

Thanks Smile | :)

You can't do this in web applications. It uses disconnected architecture. A server can only responds to requests it gets. So in web applications, your best bet is to use AJAX. Your page should give periodic requests to server to get the latest updates.

Hi Navaneeth,

Thanks for the reply.
Then according to you ,either one has to use a kind of timer ,so that a request can be ping to server after a certian peroid of time.But in gmail for any other chat based web application,how do server send a response to a client ?
Example:
"A" want to chat to "B",then it "A" send a request to server and then server send response to "B" means server is broadcasting a response to "B" without "B" making a request to server?

Any Idea for that ?

no there was no time stamp change in web.config,and no change was made in web.config wither if the change would have been made then it should not kill the session as session mode is out of process, what do you say about it ?

Hi Vasudevan Deepak Kumar,
When i select August 2008 7th,september,october and november in from date calandar popup,in to date calandar popup its getting selected December 2007 8th.

I guess this means your third party calendar control needs to be configured for non US data format ?

Surely, swapping the numbers in this line will fix your problem ?

Try installing firebug and debug the error.

You can have simple XSL to apply a transformation and draft out elegant reports, as required by the user. Isn't it?

Hello...
I've a div that displays some information but whenever i click on my submit button then this div becomes disappear but i still want to display it. And also i've set runat="server" at my div and following code in my
.cs file but it is throwing an error oject required

HtmlControl myControl = (HtmlControl)this.FindControl("divIP1");
myControl.Style["display"] = "block";

Well, calling find control and assuming it doesn't return null, is always a bug.

You can just use divIP1.Style["display"] = "block"; if it's a server control.

I've put up this code in .CSfile..
Again throwing Same error...Object required

Then you must not have a server control of that name.

Html Code of DIV...
<div id="divIP1" runat="server" style="display:none;text-align:left;padding-left:0px;" > ........
Then Server Side Code here...
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
string id = GridView1.DataKeys[e.RowIndex].Value.ToString();
DataUtility dUT = new DataUtility();
string strsql = "Delete FeedBack Where Active=1 and ID='" + id.ToString() + "'";
int result = dUT.ExecuteSql(strsql);
bindDataGrid();
bindDataGrid1();
divIP1.Style["Display"] = "Visible";
}

Well, that is plain not going to work anyhow, because attributes are case sensitive.

But, I would expect it to work otherwise. Not that I ever do this, there is obviously a wrinkle I don't know about. Did you try using a Panel or PlaceHolder instead of your div ?

i am sending complete code to u.....
JS code......

var openDiv='';

function divShowHide(myDiv,myTD)

openDiv=myDiv;
}
else
{
document.getElementById(openDiv).style.display='none';
document.getElementById(myDiv).style.display='block';
openDiv=myDiv;
}
}

Html Code here..............I am calling on Span..

int result = dUT.ExecuteSql(strsql);
bindDataGrid();
bindDataGrid1();
divIP1.Style["Display"] = "Visible";

}

Actually i want to do..when we dell the record hen show div..Because i have used 2Div in form..
and i want to show record on click event of button..

If you use a placeholder, you can set the visibility in your code behind. Tis code still won't work because you're using Display and Visible, when they are lower case. I doubt Visible is a correct value either.
