Question regarding inline expressions

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :ASP.Net
using .net 4 and vs2010 I'd like to get the text value of a column of my datagrid and insert that text into the subject line of an email. The partial code I've tried is below in bold, however, it does not produce the correct result.<Columns> <asp:BoundField DataField="FullName" HeaderText="Full Name" /> <asp:BoundField DataField="University" HeaderText="University" /> <asp:BoundField DataField="LastKnownCity" HeaderText="Last Known City" /> <asp:BoundField DataField="LastKnownState" HeaderText="Last Known State" /> <asp:BoundField DataField="LastKnownCountry" HeaderText="Last Known Country" /> <asp:HyperLinkField NavigateUrl='mailto:someone@somewhere.com?Subject=Fullname={1}' Text="Select" /> </Columns> I've also tried various other inline expressions, including <%#DataBinder.Eval (Container.DataItem("FullName")) %> and <%# Eval("FullName") %> Any help is appreciated.

Linq: how to share parameters between lambda expressions ?

When using Linq to objects, you will quickly feel the need to pass some parameters from a method to another but it's not so easy because each Linq method is not calling the following one. In a Linq sequence, each method is using the result computed by the previous one. So, local contexts are not visible from one method to another.
The compiler is using two technical different ways to let parameters go out of a method.

How Do I Enable Inline GridView Editing?

Now that you have created a site with Edit and Details views, how do you enable inline editing in a GridView control? This video shows you how, and also touches on routing.

GridView inline Master/Detail record display

This code drop is part of a smash and grab series. If you're in a rush, you can just grab this code and insert it into your application, no understanding is required. When you have some time (ya, right) you may want to review the source code.

Various SQL Expressions

A comparison is a Boolean operation that produces a true or a false result, depending on the values on which the comparison is performed. A comparison is performed between two values of the same type; for example, you can compare two numbers, two characters, or the names of two cities. To support comparisons, Transact-SQL provides all necessary operators.

What is Lambda Expressions In LINQ

A lambda expression is an anonymous function that can contain expressions and statements, and can be used to create delegates or expression tree types.

All lambda expressions use the lambda operator =>, which is read as "goes to". The left side of the lambda operator specifies the input parameters (if any) and the right side holds the expression or statement block. The lambda expression x => x * x is read "x goes to x times x." This expression can be assigned to a delegate type as follows:

Web Site to Web Application Question


I've been building web sites and for my next project I will be creating a web application.  I use a 'BasePage' class in all my projects but, since web applications do not contain the 'App_Code' folder, what is the best place/practice for the 'BasePage' class?



Inline conditional output


Is it possible to somehow output some content based upon some conditional check in Razor? If not, I hope this possibility will be added in the future. What I want to do is the following:

<option value="1" @if(ListMode == 1) { = "selected=\"true\"" }>Full list</option>

As I can't figure out a way to do this, I have to either make a helper that does it for me or write duplicate code.

connection string question from a newbie


when publishing  in the webmatrix dialogue it asks for "destination connection string" for my "database.mdf"

I was not sure what it was so I pasted this from my web.config file :

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\database.mdf;Integrated Security=True;User Instance=True

it all published ok, but wont run, so I guess it has somthing to do with this connection string or some kind of configuration issue.

My question is this, What should go in the field for "Destination connection string"

Security Question Answer Retrieval


I know there is a method built in for retrieving the encrypted password, but how do I retrieve the encrypted security answer?

What I want to do is have a member profile update screen that the end user can update their password and security question and answer. However, when they get to this page, I want to already be showing the security question (the easy part) and its answer (the not so easy part).

I have updated web.config with passwordFormat=Encrypted and have added a machineKey with the generator (forgot the link, but located on eggheadcafe somewhere).

I haven't done ANYTHING yet, since I already have a user store with hashed information. I wanted to get some functionality done before publishing, wiping the store and recreating users (only a couple developers).


Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!




C#, LINQ: (List<>) Question???


Hi Everyone,

I have a strange problem:


There is an entity (Table) called "Filters" in my .edmx which has all my tables and stuff in it (to use it for LINQ queries)

I have created a class called "CustomFilters" which inherits "Filters". So now my cutom class has all the properties of the original "Filters" class (table) and 1 more additional property that i wanted which is a List of "CustomFilters":

List<CustomFilters> children = new List<CustomFilters>();

Now i get all my records into:

List<CustomFilters> theOriginalList = new List<CustomFilters>();

NOTE: first all records are tken into a List<Filters> and then these are added into List<CustomFilters> where List<CustomFilters> for children of that record is added, and then children of the child records, and so on......

so now, every record is an instance of CustomFilters which has a property named "children" which is a list again; and each child again has instanaces of "CustomFilters", and each instance again has children...and on and on and on.....

(basiacally its a data source for a treeview in my silverlight control)

every thing is good and working as expected.


linqdatasource parameters question



I'm currently getting to know the linqdatasource control. What would happen if several WHERE parameters are added to the linqdatasource control declaritively in the aspx page but no WHERE clause is defined? 

1. is there any issue with setting up multiple WHERE parameters in the aspx markup for linqdatasource but then deciding which ones actually get used at runtime by setting the actual WHERE clause at run time? Would the unused parameters simply be ignored and cause no issues?

2. when you need to modify WHERE clause or WHERE parameters at runtime do you need to do so in an event handler? such as linqdatasource.selecting?
I see from the above link it is possible, but is that the standard way to handle controlling filtering in code behind for linqdatasource?

2b. if you use an event such as linqdatasource.selecting to add where parameters and/or modify the where clause in code will that also break the builtin sorting and paging support of the linqdatasource with a gridview?
