I was read your post: "Export GridView to Excel in ASP.Net with Formatting using C#" and is very useful. That code works perfect. But I need create a new format for a specific column in my sheet before to export it. For example:My DataTable have a column with decimal numbers and I'm trying reduce the tenths for each number.I want this: 2,874444 ----> 2,87 for a specific range. In this case I need it for all numbers in the column 13 or well said for the Column called N in Excel. Only reduce two tenths.
I used:
xlWorkSheet.Range["N"+h,"N"+h].NumberFormat = "0.00";
And no works (h is for rows, N is the column. Into a foreach).
I'm trying to execute this statement every minute with SQL Agent, I have it set up as a job:

It's trying to update a column which data type is set to decimal. Just so you know what I really need out of it, here is an example:

The answer of which should add on 0.5 to the original value. If I were to use the increase value of 60 which then becomes 60/60 it will work.I'm dividing by 60 because the increase value is per hour so I make it smaller to get per minute value. Why is it doing this?
I got a decimal member in my viewmodel and get populated from the database (say 55.5, or 100.00)
In my view I use TextBoxFor<> for this member.
Is there any way to have a number (it's actually a percentage) like 100.00 display as 100 instead, and 55.50 as 55.5?
i have some labels on a page. some id like to show 1 decimal place, and others to show the nearest whole number.how do i control the decimal places my labels show?

I have a master gridview that I am populating data to. I am am also counting records of open and closed and I want to display the percentage closed. I am using the following code. It always rounds up. In other words, if the actual calculation shows it to be 0.16 it will always display in the label as 0.2 I cannot figure out what I am doing wrong. If I just take two numbers and divide them in the code it displays 0.16676767. Here is the code I am using. The first line is on up in the code but I plugged it here to show you that I am using a session variable to add to as I rip through the code. I have all three of the variables I am placing the session variables in defined as Dim xxxxx as single.

i have a repeater item that displays a double. occasionally the double seems to be coming out with 3 decimal places like this 1165.833. im trying to force it to two decimal places by wrapping it in a string.format method but it still comes out the same:
<%# String.Format("{0:f2}",DataBinder.Eval(Container.DataItem, "pricerange").ToString())%>
How can I get the result with decimal place? The following will return 33.00, but how can I get the result of 33.33?

View 3 RepliesI'm creating an excel file using ASP.net and everything is going just fine except one column has to be formatted as a decimal to 2 places but when it pulls into excel, excel automatically formats it as a whole number instead of keeping the decimal places.
sw.Write(String.Format("{0:f}", CDbl(dr(14)).ToString("0.00"))) this produces "20.00"
but when I open it in excel it's displayed as 20...if I select the whole column and format it as a number it gets displayed as 20.00 like it's supposed to but I don't want to have to do this (I can't do that) the file is supposed to be automatically picked up and imported into another system that needs the column to be a decimal.

View 1 RepliesI have to validate for whether the string is decimal/numeric in code behind in asp.net.
View 1 RepliesSince I'm new to coding and I'm trying to understand why here is a little more detail on the question.If you have a text box and you are limiting the input to say 2 charactrs do you really need to validate the input further? What I have is a text box that has a max length of 2. Is there a security reason to add a validator to the textbox. I should add this is in Asp.net.
