ADO.NET :: Creating Dynamic Expressions For Lambda IQueryable Expressions?
Sep 30, 2010I have a ListBox that contains userNames which is inputted by a user during run time. This number of items in the ListBox is dependent on the user's input. These userNames will then be used in a Lambda expression like this:
var vHandleResult = vHandleResult.Where(a => a.UserName.Contains("userName"));
This works fine when there is only 1 user in the ListBox but doesn't produce the correct results when there are multiple items in the listBox. I tried manually creating the expression which should be written as this:
var vHandleResult = vHandleResult.Where(a => a.UserName.Contains("userName1") || a.UserName.Contains("userName2") || a.UserName.Contains("userName3") || a.UserName.Contains("userName4"));
I tried forming the "a.UserName.Contains("userName") expression as a string which is dependent on the number of the items (using foreach) and then just plug in the resulting string in the expression but it seems that it doesnt accept string as an expression.

View 1 RepliesCustom Server Controls :: Custom Server Control From Datalist Not Binding?
Feb 24, 2010I have a control inherited from datalist because I want all the same functionality but with a couple of extra properties.
I have a method that goes off and gets the data inside the control (instead of using a separate datasource ID). It's reading it from XML into a datatable.
If on the code behind of the aspx page I put the control on I put a thecontrol.databind() in the page load, all works well.
However I'd rather not have to do this, instead the control should bind itself.
I gather it's something to do with the order of events but I'm not sure what to do about it.
I don't want to reinvent the datalist wheel, just add a couple of properties and get it's own data
Sample code (some code removed for clarity)

Web Forms :: Regular Expressions - Limit The Inputs On A Webpage To A Variety Of Different Sequences
Jan 25, 2011I am trying to find a way to limit the inputs on a webpage to a variety of different sequences, and although I have worked through the regular expression library, I am still confused on how to allow decimal places and a maximum value. I initially used rangevalidators, but as you know, these only limit the inputs to a range, and have no control over the decimal places entered. A variety of limits i have been asked to implement are:
1. Range 0-45, 0 decimal places
2. Range 0-20, 2 decimal places
3. Range 16-65, 0 decimal places
4. Range 0-99, 2 decimal places
5. Range 0-1500000, 0 decimal places
6 Range 0-200, 1 decimal place
For 1 and 5 respectively, I have used
([0-9]|[0-9]d|45)$
([0-9]|[0-9]d|1500000)$
but want to be sure that I have understood the pattern correctly. How do I then go about creating a pattern for the other examples?

Combining Expressions Web And Visual Studio?
Mar 24, 2010My question:
Is it possible to design a page in Expressions Web and then use it in Visual Studio Presently, I am using an asp.net master page in Visual Studio with functionality from the VS tool box (navigation tree, login etc). These work fine but they are not very pretty. How can I keep all the functionality that Visual studio offers (I will be adding an SQL database) but have it looking better than the drag and drop tools in VS. Is it possible or not to connect an Expressions Web Master page easily, so it will drive the site already built in VS - but have a more attractive GUI?
Or, is there something that I am missing in Visual Studio - can I edit the drag and drop tools in there to build a GUI with a Microsoft feel and look?

I created this :
