if you are familiar with the " Edit In DataSheet " Feature Provided by sharepoint site to edit a Table of data in spreadsheet. i want to do the same functionality in my asp.net application, so is there any feasible way to implement this. In Brief what i want to do.
1.Data will be displayed in my Page, using Grid, List, HTML Table or by any means but in tabular format.
2.when i want to edit any value from that table , thr must be some feature or button to command like "Edit in datasheet"
3. After Edit In Datasheet Button clicked, User will see Table values in Editable format, from where he can change/add/Insert values. this i want similar to access Form if you know/sha5repoint site feature of editing table. i think this is all might have clarified my requirement. up-date me if you have implemented a sort of functionalities or any idea abt this.
I'm currently implementing a project using asp.net, c# and the MVP (Model-View-Presenter) pattern. The main purpose of this solution is to deliver a graph to the consumer, to be used by a variety of systems. It is basically a custom graph server.
The view page in this particular case has an MSChart control on it, which has to be dynamically populated and configured based on parameters in the QueryString. This can be as diverse as totally different types of data sets, display modes and so on, using a lot of the properties of the chart control.
Many of these properties are again of types which are particular to the chart control and would require the same dependencies as the chart control itself if they are to be set by the presenter.
I'm trying to figure out the best way to expose the properties to the presenter so it can work its magic.
Should I:
Just expose the whole chart object and live with a system.web type dependency in the presenter project? Make accessor and translation properties for all of the chart control properties so that I don't have the dependency, but add lots of complexity? Other, that I haven't thought of?
To me it seems that it would be against the MVP pattern to bubble a display control up into the presenter, but it seems that trying to map all the properties to DTOs or similar would be a lot of work that would add a lot of complexity, and while the solution would be somewhat more loosely coupled, I'm not sure the gain would be worth it in this case. How would you implement something like this, given MVP?

I am implementing an Isolation test in my project to ensure the data is the same in the as it was when originaly retrieved before submitting the new form data.I was wondering what would be the best way of handling this error (not an exception). The following code is the function that will determine whether or not an error should be reported, If 1 or more fields of the current record is different from the original it will return false, otherwise it will return true. How should I go about handling a false response for a best practice, Should I use a statcode and transfer to the main page displaying a message with the state code, or should I send a simple msgbox, or simply just log the error and transfer the user to main page.

View 1 RepliesI like this idea when I don't have to use slow expression compilation to be strongly typed. But the current implementation is too aggresive for me - I hate virtualization my action methods.My question is: Are you planning some (branch) implementation that will not require action method virtualization? I think that most of code could be shared in both branches...

When using a databound control the Bind() method does some magic to first extract the current value from the datasource and then pass an update back to the datasouce when an update is performed.
Now I have created a custom datasource and am supplying my own custom data which all works fine. For read only the following code works a treat. As you can see I am accessing both a named index into the collection and a property.
Now when using Bind() I cannot find a way to accomplish this. Bind() would appear to look for either an object property or a database row column (not sure how it does this) and I cannot find a way to change this.
It shouldn't be that difficult because the hard part is obtaining the data, which my code below can already do. The changes are passed back as a dictionary which should be simple. But I need a way to write my own bind method and I haven't managed to find out how.
Code:
Surname : <asp:TextBox ID="TextBox2" Text='<%#((MyCustomDataRow)Container.DataItem)["Surname"].EditDataString%>' runat="server" />
I'm fairly new to dependency injection but it seems like a proper DI implementation will be fairly complex.
For example, DI requires a centralized class that manages the configuration and resolves the dependencies at runtime.
DI is also based on the concept of using interfaces. For example, a SpecialLogger should use an ILogger interface.
The centralized DI manager class will need to register types - for example, associate ILogger to SpecialLogger.
SpecialLogger will also need to implement the ILogger interface so SpecialLogger can be used through the DI ILogger interface.
Therefore, it seems like a sln using DI will need multiple projects to support DI. Here is an example for logging:
* MyCompany.MyDivision.Framework.DI.Management - this would have the DI manager where dependency types are registered and resolved at runtime
* MyCompany.MyDivision.Framework.Logging - this would have the implementation of a logging class. The main logging class would need to implement ILogger.
* MyCompany.MyDivision.Framework.DI.Interfaces - this would have the ILogger interface.
Interfaces would need to be stored in a separate class library from the DI manager because both the DI manager and SpecialLogger use the ILogger interface. Since the DI manager associates SpecialLogger to ILogger a circular reference would be encountered without a separate class library to store the ILogger interface.
I want to use Event Aggregator to allow communication between presenters on the page. I am using currently this implementation http://kentb.blogspot.com/2008/03/event-hub.html. But in asp.net I am not sure about side effects which can occur.

use a textbox and the AutoCompleteExtender to search for the customer. For example, on the PurchaseOrder form, I have a textbox with a Customer field, and when I type in the name of the customer, the AutoCompleteExtender shows the possible matches.Now, it takes a few seconds to show the list of values, even with setting the correct values on the extender, and if the user types in the name of the company, e.g. Contoso, and leaves the textbox, there might be 2 Contoso's in the database. The AutoCompleteExtender does not continue when the user leaves the textbox, thus the CustomerId is not determined yet.
View 1 RepliesIn MVCs with which I have worked, the Controller has the job of co-ordinating a number of views, consequent to some user action against the model.
However in ASP MVC, there never appears to be more than 1 view resulting from an http request (please correct me if I am wrong). Instead the "Controller" in ASP MVC appears to be a URL Routing Target.
Also, in my (admittedly limited) experience, the Model in MVC is intended to be a model of the problem domain of the application. However in ASP MVC, the "Model" appears to be a model of the
data binding of the corresponding view.
I have been learning C# for the last year or so and trying to incorporate best practices along the way. Between StackOverflow and other web resources, I thought I was on the right track to properly separating my concerns, but now I am having some doubts and want to make sure I am going down the right path before I convert my entire website over to this new architecture.
The current website is old ASP VBscript and has a existing database that is pretty ugly (no foreign keys and such) so at least for the first version in .NET I do not want to use and have to learn any ORM tools at this time.
I have the following items that are in separate namespaces and setup so that the UI layer can only see the DTOs and Business layers, and the Data layer can only be seen from the Business layer. Here is a simple example:
[Code]....
Am I completely off base? Should I also have the same properties in my BLL and not pass back DTOs to my UI? what is wrong and what is right. Keep in mind I am not a expert yet.
I would like to implement interfaces to my architecture, but I am still learning how to do that.
I'm conducting a project in which a website should have multi-language support.Now, this website is supposed to serve about 500K+ visitors a day, so it must be super-efficient.
I've created a table of parameters {[ID],[Name]} AND a linkage-table {[objectID],[parameterID],[languageID],[value]}. I think it's the best way to deploy multi-language support while having the privilege to translate different parameters for each language.
As far as I know, server's memory is much faster than a physical HDD. Therefore, I'm planning to store ASP.NET Application State objects for my translation architecture.[URL]
