If I have JSON like this and pass it to the engine I am using to create a PDF file, the word "null" appears on the PDF. This isn't really my example, but I googled "json replace null empty string" and this was a hit, which is a good representation of my data, also:
{
"relationship": {
"type": "relationship",
"id": null,
"followed_id": null
}
}
We use a rendering engine that creates a PDF from a fixed template and variable data in the form of a json string. But our customers don't want to read that the id is "null", they want to read that the id is blank. In my C# program, the json is just a string, so I can easily do something like this:
jsonString = jsonString.Replace("null,", ",");but the issue is I can't replace null-comma with a comma, because then it's invalid json.
how to I make the rendering engine *and* my customer both happy?

i'm writing an asp.net C# web application; i have an in-memory datatable named 'table1' having three columns 'country', 'productId' and 'productQuantity'; i want to pivot that table in order to obtain a new table (suppose 'table2') having the first column 'country' as a fixed column and a dynamic number and names of columns 'product_1', 'product_2', ..., 'product_n' according to the total number of products existing in 'table1'; the first column 'country' must contain the country name; the dynamic generated columns 'product_1', 'product_2', ..., 'product_n' must contain the productQuantity that has been selled for each specific product in the specified country
i'm using Linq query expressions to write the code; the problem is that i cannot hard-code the names neither the values of the products; i cannot predict how much products exist in the datatable;
for now, i'm testing the results using the following expression :

i'm giving an example on how 'table1' looks like and how 'table2' must look like :

i have a grid view that displays a load of figures, and as there is a lot of zero's in these tables i wondered if it would be possible to just display nothing were there is a "0" ... just to make it look cleaner?

Let's take this string has an example:
D:/firstdir/Another One/and 2/bla bla bla/media/reports/Darth_Vader_Report.pdf
I want to cut the first part of the path:
D:/firstdir/Another One/and 2/bla bla bla
And replace it with **../**, and keep the second part of the path (media/reports/Darth_Vader_Report.pdf)
If I knew the length or size of it, I could use the Replace or Substring. But since the first part of the string is dynamic, how can I do this?
Update
After StriplingWarrior question, I realized that I could have explained better.
The objective is to replace everything behind /media. The "media" directory is static, and will always be the decisive part of the path.

I am working on creating a stored procedure that will output a pivot table. In the pivot table will be either the string NULL or a number. How can I reformat this in ASP.NET so the NULL value becomes a blank cell in the gridview and the number (whatever it is) becomes an 'X' ?

I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

1: I have a .html file that has some markup with some placeholder tags.
[code]...
4: PersonInfo.aspx is literally empty since I am injecting html from code-behind.
When the PersonInfo.aspx is called the html-template markup with appropriate values in the placeholder will be displayed. Also there are chances I would like to send the final markup in an html email (though that is not part of the question as I know how to email).
Is this the best way to fill values in my html-template or is the any other better alternative?
Note: This is a very simple sample example. My class is very complex involving objects as properties and also my html template have 40-50 placeholders.
So code in my step 3 will need 40-50 Replace statements.

I need to pass some values around using session state. My approach is to first check if my session variable is null and if it is not, then proceed with my C# logic. Is that correct? Will my Session variable ever contain garbage in it, like a corrupted string? Or will I be guaranteed that it is null if not explicitly set.
if(Session["MyVariable"]!=null {
// Do some logic }

I am trying to bind datetimes from a database to a Calendar in a TemplateField in a GridView using C# (following the tutorial at [URL]). The datetime is nullable in the database and this apparently kills the Calendar (one entry is null). How do you modify the SelectedDate and VisibleDate to check for null values? Do you have to create a custom binding? If so, how?
