hi ,
I want to add the values of two text boxes and display it in the third textboxes.
Both the values is numeric.
For example there is textbox1 and textbox2 and when the user enter the data in two textboxes a calculation should perform such as addition of two values and should display in third textbox automatically.
Textbox1 = 2
Textbox2 = 2
Textbox3 = 4
How it can be done.Please help.I required urqently in my project.I have tried doing that but it is throwing an error.
Regards,
Pranav

You have to convert the texts to numbers before you can do any calculation. You can use Int32.Parse or Double.Parse to parse the values.
---
b { font-weight: normal; }
|
|
|
|
|
Textbox1.Text = 2<br />
Textbox2.Text = 2<br />
<br />
Textbox3.Text = Convert.ToString(double.Parse(Textbox1.Text) + double.Parse(Textbox2.Text));

If by 'automatically' you mean you don't intend to have the computation done in an event (say click) of a fourth control (say a button), then you need to place the code in the LostFocus event of both Textbox1 and Textbox2. However, you may need to validate the contents of the two textboxes
For Example;
Private Sub Textbox1_LostFocus(ByVal sender As System.Object, e As System.EventArgs) Handles Textbox1.LostFocus
If Textbox1.Text.Length > 0 AndAlso IsNumeric(Textbox1.Text.Length) AndAlso Textbox2.Text.Length > 0 AndAlso IsNumeric(Textbox2.Text.Length) Then
Textbox3.Text = CDbl(Textbox1.Text) + CDbl(Textbox2.Text)
End If
End Sub
But you may possibly need to do more than this

Hello,
I need to implement a repeater item template at runtime and add a label to it.
How can I do this?
Thanks,
Miguel

Do a little research. It's not hard to find examples of using the repeater control with templates. Then come back and ask questions if you need help.

Hi All,

which takes input as a xml file.I am just developing default webservice
in Visual Studio 2005 which has webMethod.Is this is RPC STYLE OR Document
style webservice? if No then how build RPC style one.........?
Also How client then made request to this service which must be open on
some port.
Send me some example for RPC STyle Web Service if possible.
Thanks in Advance.

By default, Visual Studio creates document style web services. This can be a problem if you are calling the web service from a J2EE application becuase J2EE clients expect RPC style services by default. The good news is that it is easy to change the stype of your web service.
1. Add [SoapRpcService()] above your class declaration
2. Remove [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] from your web service class.
Let's look at the default web service visual studio provides when you create a new web services project:
[WebService(Namespace = "http://tempuri.org/")]<br />
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]<br />
[ToolboxItem(false)]<br />
public class Service1 : System.Web.Services.WebService<br />
{<br />
[WebMethod]<br />
public string HelloWorld()<br />
{<br />
return "Hello World";<br />
}<br />
}
Here is the same web service implemented RPC style
<br />
[WebService(Namespace = "http://tempuri.org/")]<br />
[ToolboxItem(false)]<br />
[SoapRpcService()]<br />
public class Service1 : System.Web.Services.WebService<br />
{<br />
[WebMethod]<br />
public string HelloWorld()<br />
{<br />
return "Hello World";<br />
}<br />
}

Hi Jim,
I have created one RPC Style WebService by including [SoapRpcService()].
Now after launching how to open that webService to particular port,so that
it can able to listen the request from client.
Actualy i have one code snippet
[SoapRpcMethod()]
public string GetData(string request)
{
data.XmlRequest = request;
string response = data.GetData();
return response;
}
This take string as input which is in xml format.After parsing and performing calulation returns a string response which is in same format.
so, my question is how this method listen the request from client? i.e J2EE Client.
Or is there nessesary to open a partucular port for listening client
request?
What things I should do extra for converting it to RPC Based?
Once again...
Thanks in advance.

Once a web service is deployed, it is always listening, but that is handled by IIS. Web services function very much like web pages. When you type a URL into your browser, a request is made the server for the specififed web page and the web page response with some content. A web service works very much the same way; when IIS receives a request from the client, it passes it on to your web service which then response with the appropriate SOAP response. By default, web services run over port 80, but you can configure IIS to use any port you wish without changing any code.

Hi All! I want to know how can I change the value of a text box on Page1 from Page2 by clicking on a button on page2 without using querystring,session or posting the form back. It may sound silly but I've seen this happened myself. Even if it is possible through javascript or asp.net
Many thanks

If one page is a popup window then it is possible with javascript.
opener.window.document.getElementById('yourTextboxID').value = 'yourValue'

You didn't mention popup in your original question.

What you need is a reference to the window of the page that you want to access.
If Page2 is a window opened by Page1, you get a reference to the window containing Page2 as the return value of the call to the window.open method. You get a reference to Page1 by using window.opener.
Let's say that the variable win contains a reference to the window, then you can access the document property of the window, and use that to access it's content. Example:
win.document.getElementById('SomeControl').value = 'Hello world!';
In some cases it might not work well to directly access elements of a different page. Then you can call a function in the page that accesses the element:
win.document.someFunction('Hello world!');
function someFunction(text) {
document.getElementById('SomeControl').value = text;
}
