I have a web service that is running and it shows a list of employees with their information. I created the web service with the following code:
[Code]....
The problem is 'Null' values in the datatable don't show up as empty tags in the XML so when I read the XML from the web service this is no consistency. Is there a way to show the tags even when the fields are null in the datatable or is there a better way to accomplish what I need. I'm reading this web service from a silverlight application with the following code (this application works but, it doesn't show all the employees as it skips over when no tag is present):

I have a datatable that I need to convert into a javascript array. This will allow me to do client-side validations on my webpage.
My datatable has 6 columns. X rows depending of the query results.
I was looking to use Me.ClientScript.RegisterArrayDeclaration but I just can't find how to build my 2-dimentional array to feed to this declaration.
On google I found some exemple for a 1-dimensional array, but nothing for 2-dimentional and I am not good enough in Jscript to figure it out myself.

I have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.
The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.
Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.
For Each objItem As ListViewItem In lvwOptions.Items
Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox)
decHours = CDec(objTextHrsLabor.Text)
Next
In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.
Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).
I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.

[WebGet]
public List<Cs_MT> GetSearchResult(string emailId, string localTitle, string colorGrouping)

We are calling the WCF service from our client application and get the results as IEnumerable
IEnumerable<GetSearchResult_ByEmail_Result> SearchResult = dsContext.Execute<GetSearchResult_ByEmail_Result>(new Uri(url));

this is the web method I'm using to convert my DataTable into JSON string:
[Code]....
But I'm not sure this is as good and as fast as it should be. I am sending to client side a JSON string format, but I think maybe there is a better way of doing this. I know there is JSON.NET
but I didn't see there any converting for DataTables.

I'm having a problem with reading a string from sqlserver database and use it as the text of a label,
getDescTableAdapter gd = new
getDescTableAdapter();
Label2.Text = Convert.ToString(gd.GetDesc(pid));
what i get in the form is: getDesc ! everything is right in the dataset and if i bind it to a gridview it works fine but when i convert it to string it seems it converts the table adaptor's name instead of the value.ance
