I'm starting with asp.net MVC 2. Very cool.I have been reading about the data annotations validation attributes that can be set on the view model properties.It's cool but I have a scenario where I need to determine at runtime whether one of the property is required or not.How can I achieve this ? I want to have client side validation enabled too.
View 6 RepliesI'm using one application but have multiple providers in my web.config for memberships, roles and profiles to allow my application to be used by different groups of users who need to connect to different databases.
This means I'm having to change the membership, role and profile providers on-the-fly in my code-behind files. So far I've taken care of the membership and roles a bit like this:
[Code]....
However, I'm having trouble finding out how to do the same sort of thing for Profiles. I've looked at ProfileProvider and ProfileManager but I can't work it out how to access my the profile property that I've created in my web.config file called "ScreenSize". Normally you would just write Profile.ScreenSize to read or write to the property.
Is it possible, inside a Custom Model Binder, to fire "something" that "says" the value is invalid so it gets handled by validation part?
Basically, I am getting an exception when the value for the property is invalid.
I have recently started working on ASP.NET with MVC 2 framework, and I am facing following difficulty in validating my data,
Scenario:
In my application the view (ASPX) is divided into tabs (jQuery) and each tab's content is ViewUserControl (ASCX). The main model for the view has collection of sub models for individual tabs. I use RenderPartial method to render view user control.
[Code]....
And the user control (Tab1.ascx) refers the specific model for it,
[Code]....
Now if in my Tab1Model if I put following validation
[Code]....
In the controller ModelState.IsValid is always indicates TRUE. How do I override the validation behavior such that it as well looks the items in the collection member (which holds sub models) as well.
<%= Html.ValidationMessage("FirstName") %>
<asp:Image id="voteaccepeted"
ImageUrl="~/UserControls/Vote/Images/before_accept.png"
runat="server" class="vote-accept" />
i want to change image url during run time
if( bestanswer == true)
{
// change url..
}
how i do it.
I have an application that uses multiple identical databases. When the user logs in they select the database that will be working with for that session. I am EF 4.0 for to access the database. What I can't figure out is how to dymaically pass the database name of the database from a session variable to the code in the EDMX file.
View 2 RepliesI have a website that goes out to multiple clients. Sometimes a client will insist on minor changes. For reasons beyond my control, I have to comply no matter how minor the request. Usually this isn't a problem, I would just create a client specific version of the user control or page and overwrite the default one during build time or make a configuration setting to handle it.
Now that I am localizing the site, I'm curious about the best way to go about making minor wording changes.
Lets say I have a resource file called Resources.resx that has 300 resources in it. It has a resource called Continue. English value is "Continue", the French value is "Continuez".
Now one client, for whatever reason, wants it to say "Next" and "Après" and the others want to keep it the same. What is the best way to accomodate a request like this? (This is just a simple example).
The only two ways I can think of is to
Create another Resources.resx specific to the client, and replace the .dll during build time. Since I'd be completely replacing the dll, the new resource file would have to contain all 300 strings. The obvious problem being that I now have 2 resource files, each with 300 strings to maintain. Create a custom user control/page and change it to use a custom resource file. e.g. SignIn.ascx would be replaced during the build and it would pull its resources from ClientName.resx instead of Resources.resx.
Are there any other things I could try? Is there any way to change it so that the application will always look in a ClientResources.resx file for the overridden values before actually look at the specified resource file?
I'm basically trying to get a div containing a loading gif to show on my page at runtime. I call it from a button click event as well as in the code flow. It was working before I used the AJAX Update Panels. I've since taken them out as they were causing issues with RegisterClientScriptBlock. By the way, does commenting out the AJAX Markup like this...
[Code]....
...remove them from influence?

My code is initiated from the button click event.

i'm trying to set my website's culture programmatically, so when a user clicks a button they can change the text on the page from english to spanish. here's my code:
protected void btnChangeLanguage(object sender, EventArgs e)
{
Thread.CurrentThread.CurrentCulture = new CultureInfo("es");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("es);
}
<asp:Label ID="lblDisplay" runat="server" meta:ResourceKey="lblDisplay" />
<asp:Button ID="btnChangeLanguage" runat="server" Text="Change Language"
OnClick="btnChangeLanguage_Click" />
i have a Default.aspx.resx file with a key/value of: lblDisplay.text/English and a Default.aspx.es.resx file with a key/value of: lblDisplay.text/Espanol. i can't get my Label's text to change from "English" to "Spanish". anyone see what i'm doing wrong?
I want to have my web site localized to 3 languages english, spanish, french.
Is it possible by clicking the flags on the home page set the globalization culture tweak, in flag image click?
I am making a web project now. And i meet some problems working with Entity Framework. My program needs to have dynamic model. I try to explain. So i have classes and database is created from them. At the beginning of work program checks in folder Modules for assemblies and looks for classses that needs to be created as tables in database(this classes have to become a part of ef model). And i need at runtime create database.If some new classes was added so add this tables to database, but not recreate it(as it is made by default). If i delete classes the tables are not deleted.
View 2 RepliesI have a site map on my project and I have section which get values from sql database and it changes according to querystring Id value. In my sitemap the title of the page is everytime same. but I want tpo change it at runtime. I am using multiple sitemaps and My sitemap is not the default one. its name is rootSitemap. I tried some code which I got from msdn but it seems doesn't work for me;
[Code]....
Here is my sitemappath code which is situated in my master page;
<asp:SiteMapPath SiteMapProvider="rootSitemap" ID="SiteMapPath1" runat="server"></asp:SiteMapPath>
I started out with the following code which worked fine, no problems:

I've since expanded the above so that it uses different providers according to the current logged in user. Here's the code since my changes:

I'm not getting any error messages but when I view the web page in the browser, it is stuck in a continuous loop where the page displays (correctly), then posts back to the server and displays again.
I have a GridView bound to a SqlDataSource with a default SelectCommand defined as such:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" DataSourceMode="DataSet"
ConnectionString="<%$ ConnectionStrings:MyConn %>"
ProviderName="MySql.Data.MySqlClient"
SelectCommand="select * from blah blah" />
There are cases where I have to change this query dynamically at runtime, so I do the following:
SqlDataSource1.SelectCommand = sql; // 'sql' is the new query
GridView1.PageIndex = 0;
GridView1.EditIndex = -1;
GridView1.SelectedIndex = -1;
GridView1.DataBind();
updatePanel.Update();
This works just fine actually, but when I click the pagination controls, the result set defaults back to the SelectCommand defined in the SqlDataSource1.
I am using the ASP.NET membership system and I have found the ability to 'add user to role' programtically, but I am wondering if there is a way of changing a user role?
I don't simply want to add a user to another role and I can't seem to find the 'remove user from role' command.
I've been using the following:
[Code]....
The error that I'm getting in Visual Studio is "Overload resolution failed because no accessible 'GetUser' accepts this number of arguments". I don't understand why it's not working.
By external config files, I mean .config files other than web.config. I've seen all the examples on how to edit web.config at runtime, but I want to edit a config file referenced by a configSource for appSettings. I want to modify only the external file and I will handle the app recycle.
I would like to use a built-in class to deal with the edits, but if the only option is a manual File open/parse, etc, then sobeit.
The general behind all this being a Settings page that is viewed at app startup, user sets their particulars and then saves the changes, then the real app starts up. quick and easy install app/configure page, so I'd like to leverage .config if at all possible.

There is a page in my project named Messages.aspx that shows the messages received [but obviously], using the ListView control.
I want that the user should be able to see the body of the message on the same page [Messages.aspx] just by clicking the subject of the message, which is ofcourse a link.[Messages.aspx?msg_id=some_id]. Hence the user would actually reload the same page to read the contents of the message.
Now what I want is that I should be able to write some code that would change the <LayoutTemplate> and the <ItemTemplate> of the listview during the runtime. [in the page_load event of course]
Previously the listview would look like this:
[Code]....
After the clicks any message to read it and the page gets loaded, I want the layout of the listview to look like this.

I am trying to find a way to be able to programmatically change an update button's onclick eventhandler when that button is placed within an updatepanel. If i do not include the original onClick eventhandler function in the code-behind, the app wont compile. If i do include the original onClick eventhandler function, it executes when the button is clicked even after assigning a new onClick evnthandler function.

If the querystring contains a "memberID" , I have setup an object datasource to fetch the results corresponding to the memberid from the database.
I want the name and email id fields in the formview to default to these values in the objectdatasource. How can you do this?
suppose that i have a gridview and an objectdatasource in my webform
with that i want to include several search criteria
the problem is that i want theme dynamic
for example
i have a dropdownlit with customers list
the first item in the dropdownlist is "All customers" for example
if i select it no "customer select parameter" is created
otherwise i have a "customer select parameter" for the objectdatasource and it's value is the dropdownlist.selectedvalue
i have a dropdownlist contaning years..now i want to connect my database by dropdown selection.if i select 2013 it will connect 2013 database ,if i select 2014 it connect 2014 so on..
