Hi,
I have a gridview bound to the database(columns - price, units,total) . I have a option to edit the row. On change of the value while editing I need to do some calculation based on the the value entered and update another textbox/label in the same row ( as well as sum of all the total price in footer row ie. Grand total) without doing any postback. I'm new to javascript. Can anyone help me to achieve this.
Thanks in advance.

I don't think you can do that in JavaScript or Jquery without making a trip back to the server.
If the server binds data from a database and creates a gridview object with the bound data, and then sends it to the browser, the server will expect the same data to return back on postback. If the data changes on the client side, the server will throw an exception saying that the gridview has been tampered with, and you will get the error page. This is a built-in security measure to prevent hacking.
You would have to send the gridview without the data, but with empty cells, and make an Javascript AJAX call to populate the cells, Javascript to edit the cells, and Javascript to write back the cell data, and then just destroy the page when done.
You can use an update panel to make a small async postback to the server for just the gridview, and calculate on the server side. All will be well then.
Edit:
I may be wrong, try out the post above first, but I know for sure on objects like the listbox will do that. Textbox is exempt from validation on the server side, because it's expected to change.

I'm new to web services in ASP.NET. Been trying to get my head around it recently. Here are my questions.
1. The Web Service item (.asmx that you can add to your project in Visual Studio), does that only generate an XML service (generate XML output)? What about JSON?
2. When I add a web reference to my project, and I get prompted to specify a URL, what kind of service does that have to be? For example, when I enter http://search.twitter.com/search.json?q=twitter - it doesn't work (nothing gets fetched).
3. After you create an .asmx service, how is this consumed through a non-.NET technology like PHP or JavaScript?
4. If I were to create a web service in another technology (PHP/ColdFusion), what would be the requirements so that I could easily add a web reference to a .NET project to be ready for consumption?
5. When do you ditch creating a Web Service (.asmx) and create a Generic Handler (.ashx)? What's best practice?

The default format is XML I believe, you can change one of the tags to script, to output JSON.

You must be referring to the namespace in the webservice tag. You put in your the url to your website root.
If your really trying to access that web service, you may have to go around a second time with credentials to get any data back, or it may be password protected.
CrazyPepperoni wrote: 3. After you create an .asmx service, how is this consumed through a non-.NET technology like PHP or JavaScript?
It makes no difference in my opinion. Any technology can access a web service.
CrazyPepperoni wrote: 4. If I were to create a web service in another technology (PHP/ColdFusion), what would be the requirements so that I could easily add a web reference to a .NET project to be ready for consumption?
It makes no difference, you just have to get the url and file name correct, and make the correct call to it.
As long as you know the format of the input and output, and have credentials to use it if required, it really doesn't matter what the technology is. The technology is only specific to the web servers capabilities, that is hosting the web service file.
The purpose of a web service is to provide a non-homogenous environment for 1 computer to access data from another computer.

fyi: I have faced this issue, this is generic type statement I guess. In my case the issue was with version of oracle client dll file. In your case, it might some framework installation related issue....

I am trying to convert a web application from 1.1 to 2.0 or above. when I compile my solution it gives me error in the following piece of code that
Option Strict On disallows late binding. The line of code is
Dim sqlConn As New SqlConnection(ConfigurationSettings.GetConfig("IntranetSettings")("ConnectionAsset"))
I really appreciater your help in advance.

That error occurs when you are trying to access a method or property that does not exist on the type you are using but might exist on a type that inherits from the type you are using.
Since no one else will answer the question, here's my analysis:
The ConfigurationSettings.GetConfig("IntranetSettings") will return a System.Object. You then try to access an array element ("ConnectionAsset") from it, and System.Objects aren't necessarily arrays. This is a likely cause of the error.
You should probably resort to explicitly casting the results of the GetConfig() method to whatever type it ends up being. After that, make sure that the SqlConnection() method is taking in a string rather than an object.

This is your error
ConfigurationSettings.GetConfig("IntranetSettings")("ConnectionAsset")
It's trying to grab a string value from the configuration setting called "IntranetSettings"
Normally it's just a string ...
"Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;"
But yours is stored in the project somewhere. Your need to repair the projects resource table.

hi,
I'm assuming that the button click will trigger the modal popup through the client side script. If that the case, try include this line into the script.
<script type="text/javascript">
if (typeof (Sys) !== "undefined") Sys.Application.notifyScriptLoaded();
function showModalPopupViaClient() { ... }
function hideModalPopupViaClient() { ... }
....
....
<script>
Thanks,
Bryian Tan

I think you have to load the AjaxControlToolkit client extensions on the production web server, there is a small download from Microsoft that you run on the server. I'm not sure about Server 2008, but I do remember having to load several programs to stuff like the chart controls to work.
ASPAJAXExtSetup [Microsoft AJAX Script Library^]
ASP.NET AJAX integrates client script libraries with the ASP.NET 2.0 server-based development framework. This new Web development technology extends ASP.NET, offering the interactive user interface benefits of AJAX with a programming model that is more familiar to ASP.NET developers, making it very easy to add AJAX to your applications quickly and with minimal effort. However, ASP.NET AJAX isn’t just for ASP.NET development. You can take advantage of the rich client framework to easily build client-centric Web applications that integrate with any backend data provider.

I am having an issue with canceling an event I added to the window's onBeforeUnload event, when the browser is IE (7,8, &9). In FireFox my RegisterOnSubmitStatement is sufficient to set a flag to skip the warning, but in IE that code gets called after the onBeforeUnload.
Here is the code in question:
ScriptManager.RegisterStartupScript(page, typeof(Functions), "NavigateAway", @"
window.SuppressExitWarning = false;
window.onbeforeunload = confirmExit;
function confirmExit(evt) {
var message = '" + JsEscape(message) + @"';
if (window.SuppressExitWarning == true) return;
if (typeof evt == 'undefined') evt = window.event;
if (evt) evt.returnValue = message;
return message;
};", true);
ScriptManager.RegisterOnSubmitStatement(page, typeof(Functions), "AllowNavigateAway", @"
window.SuppressExitWarning = true;
");
If you add an alert to the "AllowNavigateAway" script, you can see the behaviour in IE -> The onBeforeUnload message pops up, then the alert.
I have tried several ways to solve it, but they all have a flaw of some sort.
A) Adding a setting of the global variable on the OnClientClick event to all possible form submitters will invariably miss something. That is to say, I do not have any idea of what controls will be on the page and even if I iterate through the control tree, I am likely to miss something that it not usually a control that submits but has it's AutoPostBack set to true. (e.g. DropDownList)
B) Using jQuery to attach a method to the submit of the form is not an option because CKEditor has locked it up.
C) Tracking the postback through a hidden input fails because it is not updated until after the onBeforeUnload.
Any thoughts or ideas would be greatly appreciated.

Hello,
We have a web page which requires user to answer questions in form of dropdown list. these answers are written to database. ASP.NEt with SQL server. There is some javascript validation to make sure the user selects a value from the dropdown list.
When it is the above browser, the answers are not being captured. I have added some logging to this web page. since this is working in case of IE browsers. Listed below is the debugging statement.
Browser Type : Desktop
Browser Name : AppleMAC-Safari
Browser Version : 5.0
Browser Major Version = 5
Browser Minor Version = 0
Browser Platform = WinNT
Browser Supports Frames : True
Browser Supports Javascript : 1.4
Any thoughs/ ideas is much appreciated.

You may have a javascript error when posting back the form to the web server, that is interfering with the set value of the listbox.
You have to remark out the Javascript file, and test the form postback to the server to make sure it works, and then add the Javascript back in 1 object at a time until the whole form works.
If your using the Validator, which is javascript, then that may be returning a "return false", which cancels the form postback to the server.
At the end of validation, you need to return true, to post the form for a round trip to the server.

I'm using VB.NET and ASP.NET in VS2005 to create a web application that has some very similar code in five different webpages. This code enables/disables various controls depending on the actions allowed in the current page. I would like to consolidate this code into a subroutine in a class.vb file and call it from the aspx.vb files.
I’m using a Master Page with four contentpageholders. Only one has the controls in question, but herein lies my problem. I can access the controls on webpages not using the Master Page, but can’t make the code work with the contentpageholder.
Here is the code in the class file:
Public Sub SetControls(ByVal Controltype As String, ByVal StartCtrl As Integer, ByVal StopCtrl As Integer, ByVal SetValue As Boolean)
Dim myPage As Page
Dim intIndex As Integer
Dim objPlaceHolder As ContentPlaceHolder
myPage = TryCast(HttpContext.Current.Handler, Page)
objPlaceHolder = TryCast(myPage.FindControl ("rightcolumn"), ContentPlaceHolder)
**** If Not objPlaceHolder Is Nothing Then **** “Nothing”
Select Case Controltype
Case "TextBox"
Dim txtTextBox As TextBox
For intIndex = StartCtrl To StopCtrl
txtTextBox = TryCast (myPage.FindControl("TextBox" & intIndex), TextBox)
If Not txtTextBox Is Nothing Then
txtTextBox.ReadOnly = SetValue
Else
Exit For
End If
Next
End Select
End If
End Sub
End Class
And I call the procedure like this:
Sub LockControls()
Dim objMiscUtilities As New MiscUtilities
objMiscUtilities.SetControls("TextBox", 2, 20, False)
End Sub
Whenever I test the program the “objPlaceHolder” is always nothing, so the rest of the code is bypassed.
Any help will be greatly appreciated.

Hi,
I have a question here,
TryCast(myPage.FindControl ("rightcolumn"), ContentPlaceHolder)
In this sentence is 'rightcolumn' your contentplaceholder id in your page?
To access any control in your content form,use the below way.
Dim MyTxt As TextBox
MyTxt =CType(YOURContentPlaceHolderID.FindControl("YOURTextBoxID"), TextBox)
Hope this helps.

I tried your example and got a "rightcolumn not declared" error. If this is not what you meant tell me what I should use instead of the id of the contentplace holder and I will try that.
I've seen some posts on the web indicating that I should be using "Master.FindControl" to get to the contentplaceholder where the controls are, but then I get a "Master not declared" error. That code works in the aspx.vb page, but not in the class.vb.
I'm sure this has been attempted before, but so far my web surfing hasn't turned up any examples. It seems using a master page with contentplaceholders severely limits what you can do in a class file.
Anyway, thank you for your interest and input.
