Is There An Event That Occurs After Postback, But Before The Page Is Destroyed/recreated

May 3, 2010

My ASP.NET form contains a collection of dynamically-created radiobuttons that are created and configured in the Page_Load event handler.

Normally, I process postback data in the Page_Load handler, using the condition:

if (IsPostBack)

However, since the controls that I need to access are created IN the Page_Load handler, the postback data from the previous rendering of the page is lost. To better illustrate the problem, here is an outline of the events as they occur:

1-Page_Load is invoked for the first time
2-An unknown number of radiobuttons are created dynamically
3-The radiobuttons are configured, based on information present on the server
4-The radiobuttons are added to the page's content
5-The user selects an option, and clicks the submit button
6-The Page_Load handler is invoked for the second time
7-The radio-buttons are added dynamically, exactly as before
8-The radio-button that the user checked is seemingly non-existant for processing

It seems like I need to be processing different parts of this in different event handlers. Is there an event that occurs after postback, but while the original radiobuttons are still accessible?

Web Forms :: How To Load The DropDownList Controls With Items Before The Form Databinding Occurs

Oct 11, 2010

I have a webForm which host a gridview and a formview. The formview is used for showing/editing a record which the user Select from the gridview.

In the formview Edit template I used DropDownList controls with

I tried to update the DDL's from FormView.Load, FormView.ModeChanging, FormView.PreRender but
nothing I am getting an error like this:

How do I load the DropDownList controls with items BEFORE the form databinding occurs.

Web Forms :: Update Client Page When An Event Occurs In The Server (Code Behind)?

Nov 18, 2010

I am new to asp.net, so this might be a basic question. But I am struggling on this for more time... I have loaded a COM object in Server script using code behind (C#) and that COM object will trigger events in some random interval. I need to update the client page whenever I receive an event from the COM object from server side (code behind).My question is, Is there a way to make the client page do postback from the code behind(C#)? ie., The client page needs to be updated whenever an event occurs in the server. Is that possible? The com event does not trigger a postback since it only occurs in the server and not in the client.

Forms Data Controls :: Refresh A Gridview When Textchanged Event Occurs?

Aug 22, 2010

I have the following gridview inside an updatepanel that makes the bind from a datatable:

[Code]....

What I intend to do and I'm not getting is the following: When i edit a textbox in a row with a new value, like Desconto textbox, i want that when that textbox looses the focus, to refresh the gridview with new values that result from changes in the value of the textbox. It's a new bind as i know, the problem is how to find the correct way to trigger the textbox textchanged event, at the moment nothing is happening. I created the Desconto_TextChanged event but when compiling, i receive a compilation error:

Description: An error occurred during the compilation of a resource required to service this request. review the following specific error details and modify your source code appropriately.

Compiler Error Message: BC30456: 'Desconto_TextChanged' is not a member of 'ASP.index_aspx'.

Error Occurs When Substring Goes Out Of Bounds?

Apr 1, 2010

I have an intranet application which I have been putting together with ASP.NET. I have been using VWD 2010 Beta 2 which has been fine so far. But when I go to deploy the work i've done so far to a local IIS a variable which is supposed to be; being filled with the value from HttpContext.Current.User.Identity.Name is not being filled i.e. an error occurs when substring goes out of bounds. I believe it is because the HttpContext.Current.User.Identity.Name is not putting a value into the string variable 'username'. But it is quite strange as when I run the website project within VWD 2010 it works fine without any errors. IIS is set to Integrated Windows Authentication and Annonomous Users are allowed.

public static String getName()
{
// Store username
String name = HttpContext.Current.User.Identity.Name;
// Truncate username from domain name
String[] substring = new String[1];
// Define the token at which the string will be broken at
char[] token = { '\' };
// Split the string
substring = name.Split(token);
// Return the username
return substring[1];
}

Any ideas why when running the exact same files from local IIS gives me errors?

Forms Data Controls :: Automatically Click Button When Textbox Onblur Event Occurs?

Aug 16, 2010

I'm here again to share a problem that I'm fighting against for days. I'm developing an eCommerce Cart.

Within it, I have a repeater, inside of ITEMTEMPLATE I put one TextBox for product quantities and one Button, for update the quantity inserted on that textbox.

When the customer clicks over the Button, it fires a function that gets the content of the TextBox and do an update on my Database.

It works perfetly when it is done with the mouse click. But I need to fires the update function WHITHOUT the manually click event. When the customer just put the mouse out of the TextBox (onblur event), I want to fires that function.

Configuration :: Error Occurs In A Local Web Service?

I have upgraded my laptop to Windows7, VS2010, .net Framework 4 and then upgraded my ASP.NET Web Application to ASP.NET 4.I am now getting the error: The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?). This error occurs in a local web service thatI have written and was working before I upgraded my system.I think this has something to do with the changes made to the web.config file when my web application was upgraded to the .net 4 Framework.I have searched the forums and Goggle, but cannot solve my issue.

MVC :: Linq ChangeConflictException Occurs When Submitting DataContext Changes?

Mar 26, 2010

System.Data.Linq.ChangeConflictException: 2 of X updates failed. at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at PROJECT.Controllers.HomeController.ClickProc(Int32
id, String code, String n)

This is what I get very often. This action is done thousands of times a day, and I get this exception about once every 5 seconds. From what I understand it happens when something changes in the database in the period between creating DataContext and updating it. Am I right?How can I fix it?I just debugged the error and found the following:

[Code]....

The Stats table is updated constantly. So how can I still make LINQsave the changes. With "classical" MS SQL access through SqlDataCommand I never had problems like that.
