on 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.

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

In my repeater I am attempting to set the label format based on a value from my datasource. The following line from my repeater is straightforward enough but now how would I modify it if I wanted the "C2" statement in the ToString to pull from a field in my datasource named "MyFormat" which would contain either the C2 or N0 value? Basically switching the formatting for that label between currency and a double?
<asp:Label runat="server" ID="lblValue1" Text='<%# Convert.ToDouble(Eval("MyValue")).ToString("C2") %>'></asp:Label>
I've attempted to simply insert a statement such as Eval("MyFormat") in place of the "C2" statement but to no avail.
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 have a repeater control having columns in it.When I bind the control to a data source then some of the columns become empty when there is no data associated with it.I want to hide the column if there is no data associated with it.I was trying to implement a solution given in this thread:

I have looked all over for elegant solutions to this not so age-old question. How can I lock down form elements within an ASP.Net MVC View, without adding if...then logic all over the place? Ideally the BaseController, either from OnAuthorization, or OnResultExecultion, would check the rendering form elements and hide/not render them based on role and scope. Another approach I have considered is writing some sort of custom attributes, so as to stay consistent with how how we lock down ActionResults with [Authorize]. Is this even possible without passing a list of hidden objects to the view and putting if's all over? Other background info: We will have a database that will tell us at execution time (based on user role/scope) what elements will be hidden. We are using MVC3 with Razor Viewengine. We're utilizing a BaseController where any of the Controller methods can be overridden.
View 1 RepliesI have two update panels on my page. One of them contains a list of users which is retrieved from the database. When I click a search button (which is outside of the update panel) the users are retrieved from SQL server and displayed in a repeater inside this update panel. Each of the users has a button next to them to 'Edit'. The seconds update panel contains all of the fields for a user. Textboxes, checkboxes and what not.
My plan is to click the search button as you normally would, and then when you click the 'Edit' button on a user, the second update panel fills with their details. This works except that when I do this the first update panel is updated again and because it hasn't searched for any users it goes blank.
So what I did was set both the update panels to conditional, and then call the first panels update at the end of the search code in the search button click event. So that worked, but now the repeater inside the first update panel is not firing the Item_Command event, so I can't get the details for a user. How can I resolve this so that the repeater button works inside the conditional update panel?
This might be confusing but ill try to explain the best as i can. I have a gridview that get the data from datatable. This is simulation my grid view.
key data
1 data1
2 data2
2. data2
2. data2
3. data3
3. data3
what i want is make some conditional statement, when value "key" is changed i want to add empty row. so its suppose to be looks like this as result.
key data
1 data1
EMPTY ROW
2 data2
2. data2
2. data2
EMPTY ROW
3. data3

Just to get it work, I got a controller action that make use of a switch statement to decide which partial view to render, based on one of the members of the model passed in. (Written by someone else for what it matter...I'm just cleaning up)
The viewmodel is overcomplicated, but that's not my decision right now and just have to live with it.
All partial's get rendered passing the same viewmodel, just a different partial get called.

Currently I am working on a project at work that deals with MVC. I have never used MVC before, only dealt a little with ASP with VB, and that's it. I've dabbled in HTML but not much. I don't currently have the money for a book, so I'm using this forum. So there's a lot of jargon I may not pick up on or may ask a lot of questions, so please bare with me.Anyways here's what I would like to do, or understand. We're using ASP.NET Membership Security (not sure if that's what it's actually called) for passwords and accounts. My issue is that I've been working on other projects while the rest of my team has been working on this, so they know more about it than I do. And I don't want to take too long to understand it, but I have to find the best way to make sure the following doesn't happen:
1) When changing a password, it can't be within the last 10 passwords used for that user.2) When creating/changing a password, it cannot have dictionary words, names, phone numbers or personal data within it.3) The password must be a minimum of 16 characters.Number 3 is rather easy and completed I believe. However, 1 and 2 prove tenuous. We want to store the previous passwords hashed and we were going to save the salt used. However, I'm beginning to think that with the Membership class you can't specify the salt to hash a password. Is there a way to de-hash a password? We do not want to store the passwords as plaintext, so that is out of the question.I believe the best order (for 1 and 2) is to do 2 first (before it's hashed) and then 1. For two, I need to know how to call a function in the Model code from a <submit> tag in the View code. I've done a little research online but thought I'd ask and see if it gets answered while I'm looking for the answer.
In general, my questions are:1) How do I call a function in the ****Model.cs from a <submit> tag in the *******.aspx?2) What's the best way to compare previous passwords that are hashed? 3) If I know the salt, can I de-hash a password? (I believe the answer to this is no.)4) Can I specify the salt to hash a password? (I believe the answer to this is no.)5) If #3 and #4 are no, then should I do encryption instead of hashing?Details: MVC2, C#, Membership.

View 5 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.

View 3 RepliesI have to build a few ascx partial views in my MVC applications to encapsulate re-usable functionalities as well as archive SOR and SOC. However, I encountered challenge how to encapsulate the business logic that drives MVC ascx views.In webforms, the code behind of an ASCX control can handle a button click event and browser still shows the same page with only one postback. How can I archive the same thing in MVC? When ~/Address/Edit/2 includes an ascx partial view with a button on it that calls another MVC action - let's say ~/ShareController/CommonAction - what is the best way for the CmmonAction to return to the very same view that includes the ascx file?Perhaps I am missing a common pattern in MVC web development?

I have nested a repeater control in Gridview. Right now it is showing gridview rows and repeater header for every case(whether data is there or not for that particular grid view row in the repeater control). I want to hide the gridview row and repeater control header when there is no data present for that particular gridview row. That case I handled at code level by filtering the resulted data table.
Now the another problem I am facing: I have allowed the paging on the gridview i.e. pagesize 3. When page loads it works fine, but when I go to page 2 then it generates following error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

The problem is that the view doesn't change. When I click the LinkButton it executes the CreateChildControls and after it calls the event ItemCommand, the event calls the BuildSingleView, the ActiveViewIndex is changed but nothing happens on the page.
I don't understand why it doesn't change. Is it a problem with the order of events? What could I do to change the view when I click a LinkButton?
Here is the full code-behind code (the Initialize method is the method that executes immediately after CreateChildControls) http://pastebin.com/2qwrKNxf

View 3 RepliesI have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
