I am using a form view to update details off activities, i have used the asp.net wizard to update the activities but for some reason in my VB page my textbox which is in the formview is not picking up.
[code]...
Basically what I am trying to write is: How can I rewrite this statement so that the textbox and the dropdownlist is recognised in the vb page?
I need to create a web application where the layout of the site is entirely programmatically generated - about the only thing that's done declaratively in the markup is the header. Basically, it's one of those AJAX-enabled entire-site-within-a-single-page type of sites where huge chunks of content (structured as modules such as navigation panes for example) are swapped in and out on the fly. From lowest-level to highest-leveled, the options I've considered are:
Classic ASP - Since ASP provides full control over the final output, this would be perfect if not for the lack of separation between logic and presentation and the subsequent lack of code reusability. ASP.NET MVC - REST and MVC routing seem like a poor fit, since there's only 1 actual webpage. Also, interpreting and transforming data and even the UI itself based on business rules (as opposed to direct user input) lies well outside of the deterministic CRUD operations that MVC excels at.
ASP.NET Webforms - Tried something like this using Webforms in the past, but ended up fighting with the ViewState and Postback event model every step of the way. Needless to say, performance was extremely poor and the codebehind was a mess due to the complex logic needed to fully and precisely regenerate each and every single aspect of the page on every single Postback. Silverlight - To be honest, I've never used this. Non-Microsoft technologies - None of the popular ones (PHP, JSP/J2EE, Flash) are entirely suitable either.
I have a program called Bartender which is a labeling program and it can use Visual Studio as an interface. I have been given the task to make our staff have an easier way of processing a label.
The data which I need is on our P:/ NOTAPE directory. Now in this folder is a list of text files which our ERP system generates.
I want the user to open up a form and have the ability to type in the Batch file number and press return(TextBox1). On pressing the button(Button1), the File will then be picked up and then passed on to Bartender which will then go through the procedure of asking how many labels need to be printed.
This is my code so far.

i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
I have two texboxes (text_start and text_end) both using calandarextenders to pick dates. What I im trying to do is when the user picks the "text_end" date - this will force an update panel to refresh. This updatepanel holds a single dropdown whose sqldatasource uses both dates as parameters.
View 3 RepliesI've just deployed my first ASP.NET MVC 2 site, and all appears to be well except I've run into an issue with IIS banning double-escaped characters, which I was relying on for a few routes.As I don't have control over IIS (it's on a shared host) I've decided to go around the issue and replace the spaces with underscores in my URLs. Have tested and verified that this works on my local machine, and deployed the two new model classes which contain the methods that url-encode and url-decode the various bits that need this.
However, the remote website hasn't apparently noticed that I've updated the code. I've edited web.config a couple of times to try and force a recompile, deleted the remote model classes and reuploaded them, and googled around for any other reason why this would be happening.
The 'while (dr.Read()) statement in this code set is not process all the rows picked up by the sql statement in the access file. It will only process the first row found and ignore the rest. I can't seem to figure out why.

ASP.net SQL datasource C# code behind
I want the webpage to show a message that there is no data selected,
Instead of showing blank details view
here is a picture of blank details view:

What C# code do i need to use so that, whenever I enter that page, only an error message will show up
instead of the details view ..etc.
Scenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
This is the first time I have been working on databases and I am trying to insert data using an object datasource but no data is being inserted and no exception is thrown. I'm not sure where I am going to wrong. I am putting user data into session variables and inserting the session variables into the dataacess class layer and have a try and exception but nothing being thrown. Any help would be really appreciated because I don't know even where to start looking with this or how I can get the error to be thrown. Please see some of my code below to give an idea of what I am doing

I have integrated MVC into an existing web forms application which is an in house CMS system. There are two HttpModules. The first one is part of the in house CMS system and does url routing (for the web form pages) along with other required actions. The system creates routes from records in the database and if the page is an MVC Controller, the first HttpModule that belongs to CMS system does not do any more routing and the UrlRouting module should find the route and handle it. Locally it all appears to work fine with the built in Visual Studio debugger webserver. However when published up to remote webservers, all MVC pages result in a 404...even statically created routes on application startup. At the moment, the external webserver does note have remote debugging enabled so I'm stuck there. I am assuming it's related to the multiple HttpModules since standalone MVC applications do work fine on the remote webservers.
View 3 RepliesI have an aspx page that references a server control from an assembly and lives in Sharepoint (knowledge/experience in Sharepoint is not required to answer this question, i'm simply giving you context). The implementation looks something like this:
<%@ Register TagPrefix="wc" Assembly="Test.Controls" Namespace="Test.Controls" %>
<wc:WYSIWYG runat="server"></wc:WYSIWYG>
I can NOT change the .aspx page's content which currently lives in Sharepoint and I have to to take the same code and run it outside of Sharepoint but still on an ASP.NET environment. It's cool and crazy at the sametime, I know.
When this aspx page is running in Sharepoint, I have to get the WYSIWYG editor control to use Sharepoint's WYSIWYG control. When the same aspx page is running outside of Sharepoint but still in an ASP.NET environment, I need it to use a different server control that's not dependent/from Sharepoint. How could I modify the code-behind to perform this toggling? Is this even possible?
I'm new to this community and got newbie question, briefly in data access in asp.net what is the difference between accessing dataset using typed Dataset and using data sources controls like SQL data source control ...? As I noticed that using data source controls is much easier, but it allows only one data access method i.e. only one query... am I right with that....

I am trying to make a way so that I can have a group with items in it, each one of the items (which is an object in a list) having a double type value, the total of all the items in the group is 100 when you add up all their properties. The purpose of this is that there can be random selection of the items.
for example:
item 1 percent property: 25.0
item 2 percent property: 25.0
item 3 percent property: 25.0
item 4 percent property: 25.0
When a request comes in, I need to be able to pick 1 of these items at the rate of 25% so that after a while (more and more requests) that each of these gets very close to 25%. I have tried looking at random numbers but pulling a number back seems useless in this case because for example if a random number retrieved was the number 5.4, how would I send it to an item? I cannot keep a history of the item requests so that I can factor that in. I need to be able to pick a random number and over time have each of these 4 items be selected an equal amount of times, the percentages and amount of items is going to change constantly but the sum of all the percent properties within a group is 100%. What is the best way to accomplish this in C# with a web form?
I have a custom dead letter queue service to pick up messages from DLQ. This service picks up failed message from DLQ and tries to resend to a different end point. If the new endpoint doesn't work, it rolls back transaction. This works great. Here is the code.
{
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single,
ConcurrencyMode = ConcurrencyMode.Single,
AddressFilterMode = AddressFilterMode.Any)]
public class FDPDLQService : IFDService
{
FDPManager _fdpManager = new FDPManager();
[OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete = true)]
public void ProcessFDMessage(FDMessage message)
{
//System.Diagnostics.Debugger.Launch();
try
{
MsmqMessageProperty mqProp =
OperationContext.Current.IncomingMessageProperties[MsmqMessageProperty.Name] as MsmqMessageProperty;
// if message log required, and configured, log the incoming message
try
{
ChannelFactory<IFDPRouter> factory = new ChannelFactory<IFDPRouter>("IFDPRouter_EP");
IFDPRouter proxy = factory.CreateChannel();
string ep = proxy.GetNextEPForGivenEP(OperationContext.Current.IncomingMessageHeaders.To.ToString());
if (ep == null || ep == string.Empty)
{
throw new EndpointNotFoundException(Common.Constants.FDP_NOT_FOUND_EXCEPTION_MESSAGE);
}
// Process message with next end point available
_fdpManager.ProcessFDMessage(message, ep);
}
catch (EndpointNotFoundException enfe)
{
ExceptionManager.HandleException(enfe);
Transaction.Current.Rollback();
//throw;
}
catch (Exception ex)
{
ExceptionManager.HandleException(ex);
Transaction.Current.Rollback();
//throw;
}
}
}
}

This works great.
But if all endpoints are not available for a long period of time, and if service rolls message back to the DLQ for a long period of time, after a certain period of time service stops picking up messages from DLQ. I am not sure which configuration is responsible for this.
Here is what I need to do:
- SELECT from a table
- Do something to the data after the SELECT but before anything else
- let the controls that are bound to my data see it.
I've already got working code to Undo my something when Updating or Inserting
These are the requirements:
- use a plain-jane SqlDataSource to do the SELECT
- doing the something has to take place at the SqlDataSource, not in events of the databound controls.
From the MS site the SqlDataSource.Selected event is where I should do "post-processing" however I can't find any examples of doing so.
