I'm binding my DataRepeater control to a table that has many columns. I'd like to only display a subset of those, depending on what is populated.How/where should I do my contitional tests within a dataRepeater? This is the code within my itemtemplate:
View 1 RepliesI have bunch pages and I need to validate data there. If culture for example "es-ES" I should use one validation logic, if culture "en-US" than another validation logic. For example I need validate phone number. Minimum length is 11 digits. For other culture 9 digits.
View 3 Replieson my repeater i builed a table and want to show a colum just for user that is in role admin.i need to remove the column in the HeaderTemplate and in ItemTemplate.i could use data logic and add a db column that will be boolean, but then i need to send to the SP the user role.
<asp:Repeater ID="TemplatesList" runat="server">

I need to check in conditional logic if a user has more that one role associated.Script should work like:

I have a code behind page with two functions that return two counts (iCount and iCount2). In my repeater table I can display the results of the functions just fine, but now I need to do some conditional logic based on the results of the functions, eg:If iCount =>3 AND iCount2 =>1 Then

View 1 RepliesI was wondering if setting a default value for a SelectList is considered to be presentation logic or business logic? For example, if a requirement is that an Employee cannot be saved without a Location, but 99% of the time the location that would be selected is a particular item -- say Atlanta. Because of this, the location SelectList should be defaulted to Atlanta when ever a entry screen for a new employee is displayed. Should I be defaulting the location in the model or in the view-model? One thing I realized is that the unit tests become awkward because in both cases, I'd be forced to test against a location that will always be present in production but I cannot create a unit test with my own test dataunless "Atlanta" was in the set of locations being used in the test.

I'm having trouble figuring out how to do the following:On every page (or every page I so desire), I'd like to put a common control widget (e.g. think - Search functionality that contains a textbox+button). What's the best way to do this, and who handles the submit button (assuming it is a submit button)?i.e. what does my ViewUserControl look like? Does it have a form? does it use jQuery onclick""? Does it post to the main View's action method, or can I redirect it to another Controller/Action
View 5 RepliesI have the following Dropdown List
[code]....
My problem is that some of the users that used to be in the list have left the company so we want to mark them inactive. When they are inactive they should not show up in the DDL to be selected to be assigned to. But there are existing records that they are already assigned to. If they are no longer able to be assigned their is a column called IsActive in the db that is set to 0. The Datasource filters for only == 1 when filling the datasource.
When it tries to render the control where a selected value is not in the list the Browser throws an error. I can not seem to find an event where I can intercept and set a value that is legal.
The solution I would like would be to add the listItem to the Control in the code behind then call the bind("AssignedTo") in the code behind instead of in the aspx page. This way linq would still handing the update of the DB record for the update event.
I have a nested accordion control for categories and sub-categories with a gridview to display the data. What I am trying to do is to hide the "Header Template" when sub-category is "Not Defined" but the results are usually inconsistent and seems like if i define HeaderCssClass, HeaderSelectedCssClass declaratively then it overrides the conditional css styles defined in code (c#) for OnItemDataBound event whereas if I don't define declaratively then css in code is not consistent.
I am not sure how to approach this or if I am using the correct event for this.
In the code - I used label's forecolor proprtery to match to the background as a workaround for now but not happy with it.
I can set lblSubHeaderId.Visible = false; which works consistently but then I still have this predefined HeaderCssClass, HeaderSelectedCssClass which is still shown as a placeholder/ just a horizantal line for the headers where lblSubHeaderId is set to false.
My structure is:
--AccordionCategory
-- AccordionSubCategory
-- Gridview

I have a class constructor which accepts a Listbox.
[Code]....
I need to be able to pass another control type and execute the exact same logic in one of the methods... Seems like a use for Generics... I'm not so sure about the syntax... The type of control that I will pass is a rad combo box which has many of the same properties of the listBox control. However, RadComboBox does not inherit from listBox or dropDown so I am unable to cast. When changing the signature of the constructor to As RadComboBox as well as the property and field the method works as expected. I am trying to avoid duplicating code here.
I have a repeater control with a delete button on each row. I also have a link on the same page (not within the repeater) that I only want to be visible when the repeater contains at least one row.
My problem is that, when the delete button on the final row is clicked, this triggers a postback during which the ItemCommand event is called to process the delete click. However this event is processedafter the Page Load event in which I would normally render or not render the conditional link. So I don't know at the time I'm rendering the link whether the user has just deleted the last row.
Am I misunderstanding the chain of events or is there a better way of handling this? Could I, for example, determine from the Sender & e arguments available within the Page_Load event, that the postback has been triggered by clicking the delete button in the repeater? The only other way I can see of dealing with this is to force a second postback once the final row of the repeater has been deleted which seems like overkill.
I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?
I have a page in which i need to show data in the form of a grid. Each row in the grid is made up of 2 sub-rows, the first sub-row consists of a dropdown, a textbox & a textarea. Whatever is entered in these controls should be displayed in the second sub-row in the form of labels at runtime (i.e. using javascripts)
There can be multiple rows like this. The grid would have a max of 30 row, not more than that. create this which one would be better, in terms of performance & complexity, a GridView or a DataRepeater?
I've got a C# MVC 2 application using EF 4. My DAL project gets data from the Model, translates them into POCO's and returns ViewModels to the BLL which is called from the controllers.I've set up validation attributes on the POCO classes and that works for "Required" fields etc. I would like to add business logic such as "From" has to be before the "To" date. Can this be done on the POCO classes so it is automatically validated client-side in the view?
Also, I would like to add some functionality to the BLL layer such as checking if a resource is already booked between the From and To dates to avoid double bookings. This should fire before the ViewModel is saved. I tried a Try/Catch statement in the controller so that I can throw an error in the BLL, but I don't understand how to return this error to the view with an appropriate error message added.
I need to assign channel for each schedule. There can be as many concurrent events as number of channels allocated for the customer. I.e if the customer is allocated 3 channels then he can have 3 concurrent events. If a channel was allocated to a event then the same channel cannot to allocated to another event that falls under same time but the same channel can be allocate to another event if the time differs.

View 9 RepliesDoes anybody know how to implement this new feature of the MVC 2 RC?
Here is verbatim what ASP.NET MVC 2 Release Candidate Release Notes says:
"...Buttons in a form can specify that they do not cause validation logic to run. The default is that every button in a form causes validation logic to run, and if validation fails, the validation logic blocks submission of the form. Enabling validation selectively for buttons lets you create forms .

As I am learning and working on Asp.Net MVC application, I want to know that what is the better place to write Business Logic and Data Access logic in MVC.Where should I write DataAccess and Business Logic among three layers (Model, View and Controller) ??Could anybody please tell me the correct way to write the code for this.Scenario: I want to retrieve all the employees where employee name like 'Mi%' ( I have SQL procedure to execute and retrieve the data.)PS: Want to know that where I should create instance of Business Logic class and where I should create instance of Data Access layers class?
View 3 RepliesTrying to figure out the best way to organize a ASP.NET MVC site. Take a very simple 1..N relationship: Company can have many Contacts, Contacts must have exactly one Company.I have your typical routes:
Company/Index (list all companies)
Company/Details/{int} (details of Company {int})
Company/Create (create new company)
Contact/Index (list all contacts)
Contact/Create (create new contact, company is selected from drop down)
Now if I wanted to create a page that created a Contact in the context of a Company (from the Company detail page) so that the required company is filled in/not editable), what would be the best route of going about that, while not duplicating code where possible.Not sure if I can leverage the Contact/Create logic/view from the Company controller (and be able to route back to the Company Details page when complete), or mess with the routes to do something like Company/Details/{int}/Contact/Create (not even sure if that makes sense or would work)?There has got to be a better way then me adding my logic and view for adding a Contact into my Controller view and having it duplicated.
