It has nothing to do with ASP.NET, that's the way the web works Roll eyes | :rolleyes:

. Maybe you should do some research about this "problem".

That is how Web Applications work. A typical Request and Response model.

XmlHttp or AJAX to refresh only a section of the page.

It doesn't. You navigate to a new page, but you get the same effect as refreshing as you are navigating to a page with the same address.

There is no solution, as there is no problem.

Experience is the sum of all the mistakes you have done.

Hi!

I am using thread to send multiple/bulk email. But my thread is not calling the me method that send emails.

I work well on localhost. But when i upload it on server it didn't call the method (sendNewsletter_1).

I am using following code

public static bool sendBulkEmail_1(int newsletterID)
{

m_newsletterID = newsletterID;

Thread threadMail = new Thread(new ThreadStart(sendNewsletter_1));
threadMail.IsBackground = true;
threadMail.Start();
Thread.Sleep(2000);

return true;
}

public static void sendNewsletter_1()
{
Log_1("SendNewsLetter"); //just write this test string to a file. Its just or testing.

}

Hi,

I have created a five star rating control. I have used ASP.Net 2.0 Clent Callbacks to implement the same. Following is my code

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="RatingControl.ascx.cs" Inherits="RatingControl" %>
<%@ Implements Interface="System.Web.UI.ICallbackEventHandler"%>

<script language="javascript" type="text/javascript">
var totChecked = "<%=totChecked%>";
function callSwapImage(strVal)
{
var countRec;
var imgName;
for (countRec = 1; countRec<=parseInt(strVal); countRec++)
{
imgName = "imgStar" + String(countRec);
document.images[imgName].src = "images/starGold.gif";
}
}

function callSwapRedo()
{
var message = "0";
var context = "";
CallServer(message, context);
}

function onImgClick(strVal)
{
var countRec;
var imgName;
var message = strVal;
var context = "";
CallServer(message, context);
}

function ShowSuccess(sMessage, Context)
{
for (countRec = 1; countRec<=parseInt(sMessage) + 1; countRec++)
{
imgName = "imgStar" + String(countRec);
document.images[imgName].src = "images/starGold.gif";
}
// for (countRec = parseInt(sMessage)+1; countRec<=5; countRec++)
// {
// imgName = "imgStar" + String(countRec);
// document.images[imgName].src = "images/starWhite.gif";
// }
}

</script>

<asp:Image ID="imgStar1" name="imgStar1" runat="server" onClick="onImgClick('1')" onMouseOver="callSwapImage('1')" onMouseOut="callSwapRedo()" AlternateText="1" ImageUrl="~/images/starWhite.gif"/>
<asp:Image ID="imgStar2" name="imgStar2" runat="server" onClick="onImgClick('2')" onMouseOver="callSwapImage('2')" onMouseOut="callSwapRedo()" AlternateText="2" ImageUrl="~/images/starWhite.gif"/>
<asp:Image ID="imgStar3" name="imgStar3" runat="server" onClick="onImgClick('3')" onMouseOver="callSwapImage('3')" onMouseOut="callSwapRedo()" AlternateText="3" ImageUrl="~/images/starWhite.gif"/>
<asp:Image ID="imgStar4" name="imgStar4" runat="server" onClick="onImgClick('4')" onMouseOver="callSwapImage('4')" onMouseOut="callSwapRedo()" AlternateText="4" ImageUrl="~/images/starWhite.gif"/>
<asp:Image ID="imgStar5" name="imgStar5" runat="server" onClick="onImgClick('5')" onMouseOver="callSwapImage('5')" onMouseOut="callSwapRedo()" AlternateText="5" ImageUrl="~/images/starWhite.gif"/>

// remCount = 5 - currentRating;
// for (countRec = 1; countRec <= currentRating; countRec++)
// {
// imgButName = "imgStar" + countRec.ToString().Trim();
// ((Image)this.FindControl(imgButName)).ImageUrl = "images/starGold.gif";
// }
// returnValue = eventArgument;
//}
returnValue = eventArgument;

}

public string GetCallbackResult()
{
return returnValue;
}

}
------------------------------------------------------

The problem I am facing is that when I click on an image to rate, the OnMouseOut also activates and the images don't show rated.

Also, since I am a novice, I dont know how to pass value of rating on image clicking to the page that implements the control.

Please help

you can use simple javascript or builtin AJAX control for this purpose...

I know, but I wish to make my own control

Hi,
i am using asp.net 2.0 , C# , VS2005.
In a web page i have six dropdownlist control and couple of checkbox list .
On add button click i have to display it to gridview control(as this row can be editable) . further i have to insert whole data to database

please suggest me ways of doing the same. or give some important link.

Thank you.

imran khan

I m not getting what this second line says

On add button click i have to display it to gridview control(as this row can be editable).

As i understand from that,
On page load ur grid is empty Then u Click add Button at that time u want to show all ur controls appear in grid and then add data to ur database.
And this thing u want done with the controls placed in grid?

Believe Yourself™ :->™

is it port number 1433?

thanks

Yes, SQL talks over TCP 1433 unless you use the Netowrk Configuration tool to change that port.

if(!ispostback)<br />
{<br />
	viewstate["index"]="0";<br />
}

On Next Button event

if (viewstate["index"].ToString()=="0")<br />
{<br />
	//Get question from arraylist with 0 index<br />
        int.parse(viewstate["0"]) +=1;<br />
}<br />
else<br />
{<br />
	<br />
	//Get question from arraylist with viewstate index number<br />
    string quest=arrlist[int.parse(viewstate["index"])]<br />
	<br />
	//check if question is from last array index then disable next button<br />
	if(int.parse(viewstate["index"])==arrlist.count){<br />
	 //disable next button}else{int.parse(viewstate["0"]) +=1;}<br />
}

On Previous Button event

if (viewstate["index"].ToString()=="0")<br />
{<br />
	//Get question from arraylist with 0 index<br />
	//disable previous button<br />
         int.parse(viewstate["0"]) +=1;<br />
}<br />
else<br />
{<br />
	<br />
	//Get question from arraylist with viewstate index number<br />
	string quest=arrlist[int.parse(viewstate["index"])]<br />
        int.parse(viewstate["0"]) -=1; <br />
}

Hi All,

Here i m stucked with a problem and devoted my best half the day to solve the same but cant get any sucess.

my problem is, i want to trace the browser close button event and perform some operation on the same.

I have tried all the things like window.close(), onunload event but cant able to find the correct sollution.

i dont want my function to call at page refresh, i wants to call the same only when user clicks to X button of browser.

Please help

Hello Forum
Always be in touch to help about the topic ASP.NET

You can Icallback and execute your code in code behind side before closing window.check return argument and you can close window.
The other way is create one method in code behind side and call this method using javascript and close window
for example
In html source page
<a href="javascript:CloseWIN();" >Close</a>
In code behind side
function void CallMethod()
{
//code here
}

javascript
<script .................>
function CloseWIN()
{
<% CallMethod() %>
window.close();
}

I think u want server side validation that been done from client side? Is it so?

U can try by putting an alert to the very beginning of a javascript to check.
