Forms Data Controls :: Using Multiple Tables Within A Single DataSet And Single SqlDataSource?

May 19, 2010

I have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.

While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.

Stop The Tag Builder Escaping Single Quotes MVC 2

Oct 13, 2010

I have the following HtmlHelper method that I want to create a button that does a redirect with JavaScript:

public static string JavaScriptButton(this HtmlHelper helper, string value,
string action, string controller, object routeValues = null, object htmlAttributes = null)
var a = (new UrlHelper(helper.ViewContext.RequestContext))
.Action(action, controller, routeValues);
var builder = new TagBuilder("input");
builder.Attributes.Add("type", "submit");
builder.Attributes.Add("value", value);
builder.Attributes.Add("class", "button");
builder.Attributes.Add("onclick", string.Format("javascript:location.href='{0}'", a));
builder.MergeAttributes(new RouteValueDictionary(htmlAttributes));
return MvcHtmlString.Create(builder.ToString(TagRenderMode.SelfClosing)).ToString();

The problem is that the line that creates the onclick handler is getting escaped by the tagbuilder, the resulting html is: <input class="button" onclick="javascript:location.href=''" type="submit" value="Return to All Audits" />

DataSource Controls :: Using LINQ To Pull Out A Single Value From A Single Result Row Of A Join Query?

May 25, 2010

For context: First of all, I am new to LINQ, as I have been using SubSonic for quite some time now.

I have two tables, Users, and Affiliates. They both have a very typical schema. The FK that joins them is the UserId field, which is in the Affiliates table. I want to create a LINQ query that pulls the Username from the Users table using the AffiliateId value. The AffiliateId is a primary key of the Affiliates table.

I have tried to accomplish this using many variations of the following code:


In the above query, I expect to get a single row result set. However, I instead receive the entire table of results.

How can I make this work? I have yet to see an example or article out there to do what I am trying to do.

Disable EventValidation For Single Control?

Jan 11, 2010

I know this is a very debated topic, and usually when you are thinking about this as a solution you might want to rethink your UI logic.

I know I can pass validation using ClientScriptManager.RegisterForEventValidation. But, I'd really like to know. Is it possible to remove event validation for a single control? Is there a way work around for this?

I'm modifying a DropDownList, from the client side after it's rendered.

Disable Windows Authentication On Single Location?

Mar 7, 2011

I have a web application and I want to provide anonymous access to a couple of the web services in it so that we can access the web services from computers without a windows login on our network.

I've tried the stuff here Disable authentication on subfolder(s) of an ASP.NET app using windows authentication. I've done this:


These both "work" in that they allow access to the web service for anonymous users. However, it seems that IIS still sends an authorization challange because when I access the service from a browser I get a box to enter my username and password. If I hit cancel I get access to the page anonymously. However, some of our clients don't handle this well and just fail because of the 401 return code.

Is there a way to completely disable the windows authentication on that single location such that IIS will not try and establish a windows authentication?

I currently cache everything possible on my site (images, JS, CSS). There is only one JS file that I need to be loaded fresh every single time. How do I omit just one file from caching, using web.config, whilst leaving everything else cached?

C# - Update Only A Single Item In Linq?

Nov 10, 2010

Currently I update a single item in a database as follows:

var master = (from tmi in db._Masters where tmi.Id == Id select tmi).FirstOrDefault();

This strikes me as inefficient, as (I think) I am pulling out a full DB row to just update a single value. Is there a more efficient query I can use?

How To Invalidate A Single Data Item In The .net Cache In VB

Jun 3, 2010

I have the following .NET VB code to set and read objects in cache on a per user basis (i.e. a bit like session)

'' Public Shared Sub CacheSet(ByVal Key As String, ByVal Value As Object)
Dim userID As String = HttpContext.Current.User.Identity.Name
HttpContext.Current.Cache(Key & "_" & userID) = Value
End Sub
Public Shared Function CacheGet(ByVal Key As Object)
Dim returnData As Object = Nothing
Dim userID As String = HttpContext.Current.User.Identity.Name
returnData = HttpContext.Current.Cache(Key & "_" & userID)
Return returnData
End Function

I use these functions to hold user data that I don't want to access the DB for all the time. However, when the data is updated, I want the cached item to be removed so it get created again.

How do I make an Item I set disappear or set it to NOTHING or NULL?

VS 2010 Binding Single Item Without Using FormView / DetailsView / Repeater

Aug 11, 2010

The title pretty much explains it. I want to bind a single item to a detail type control. I can bind to a repeater perfectly fine and obviously only one item will be displayed. It seems like there would be a better suited control for this. I know about FormView and DetailsView but they both generate a table which I don't really want. Something similar to the Repeater since it doesn't generate any content other than what you put in the template.

GridView Making A Single Edit Item Template Take The Entire Row?

Jan 6, 2010

I've got this gridview. The gridview uses TemplateFields as the number of fields in the database's table. What I do next is use an ItemTemplate to present the correct column info.

Now, problems rise when the user click's Edit. Since I can only use EditItemTemplate to edit I am resulted with a control in each column. What I really want is to have a single row with no columns so I can easily style the edit mode (having a table with a different layout for example).

Is this possible?

Change Single URL Query String Value?

Sep 28, 2010

I have an ASP.NET page which takes a number of parameters in the query string:


This would display the first page of search results. Now within the rendering of that page, I want to display a set of links that allow the user to jump to different pages within the search results. I can do this simply by append &page=1 or &page=2 etc.

Where it gets complicated is that I want to preserve the input query string from the original page for every parameter except the one that I'm trying to change. There may be other parameters in the url used by other components and the value I'm trying to replace may or may not already be defined:


In this case to generate a link to the next page of results, I want to change page=1 to page=2 while leaving the rest of the query string unchanged.

Is there a builtin way to do this, or do I need to do all of the string parsing/recombining manually?
