If I have a string/integer that looks like 123, how can I convert that to look like 12.3?Basically what I need is something faster (if possible) than thisMath.Round(Double.Parse(input / 1000), 1).ToString

I am using Ajax extender controls with asp.net 3.5 in particular MaskedEditExtender.My settinngs are:
Mask = 99.99
InputDirection = RighttoLeft
MaskType = number.
I can't seem to achieve what I want which is to set the focus just to the left of the decimal point. I try both InputDirection RightToLeft and LeftToRight. They both have problematic behavior. The example given by Microsoft on their web site, is close to want I want but I cannot achieve these results.See

View 4 RepliesI have a MaskedEditExtender set for a TextBox that will receive a fee amount. I want the user to be able to type the "." decimal when the amount contains a decimal value (123.45). But if the amount has not decimals (123) I want the mask to automatically fill the 2 decimal with zeroes and also enter the "." decimal point (123.00).With the following mask I'm able to enter a full number (999) and get the zeroes but when user enters 85.85 it will be 850.85 so I change the direction RightToLeft but I'm not even able to type the first character.

I'm trying to convert a string to decimal but I get this exception:
Exception Details:
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'string' does not contain a definition for 'AsDecimal'
Here is the code:
decimal PriceHT = 0;
var PriceRequest= "SELECT * FROM Price_" + HttpContext.Current.Session["PriceTableId"] ;
foreach (var Price in Database.OpenFile("Base.sdf").Query(PriceRequest)){
PriceHT = PrixceHT + (Price.PT).AsDecimal(); //Price.PT returns a string
}
I have 6E-11,4.4E-11 values in db and I am converting it to decimal. I have C# code:
string mystring = "6E-11";
decimal myno =Decimal.Parse (mystring, System.Globalization.NumberStyles.AllowExponent);
but it still not work.
Just to be forward, my .net and c# expierence is very limited, that one could say I'm a complete noob :) However I do have some grasp on OOP as I usually work in PHP (FWIW). My problem seems to be with this line:
Session["total"] = dt.Compute("SUM(price)", "").ToString();
which will output a total of say "9.2" where as the price is "9.20" from a few record lines as such:
dt.Rows.Add(strRecord, 9.20, dropDownListDistrict_stepTitle.Text);
thus 9.20 + 9.20 = "18.40", but the page displays "18.4".
The label that displays the total sum is:
<asp:Label ID="labelTotal3" runat="server" Text="0" />
From what I've gathered, I'm suffering from some kind of type casting problem? Hopefully I haven't missed anything, its a bit difficult to show all the code but hopefully someone can point me in the right direction? Question is; how can I get an extra decimal place to show up on my sum (or why is it dropping the last decimal place?).
I have a string, that could look like "123,34", "123123,09", "1234", "123.34", "123123.09"

Due to the culture of the ASP.net thread may differ, because my application supports localization, I need to find a safe way to convert the most likely user input into a decimal.
How is that possible?
I tried various Decimal.Parse attemps, that all failed so far.
Solution:
My final solution was a mixed one. I used string replace to ensure my date is formatted into the specified CultureInfo I used for parsing
I have below digits. I want to show one digit after to decimal. How to format it?

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:

how to convert the string to 3 decimal place?i want 0.033 for below:

I have a field in my products table called dProductPrice which is a datatype of money. In my datalist i need to display the field as currently it shows price as e,g, 1.3500 but i need it to 2 decimal places so it is 1.35? in my datalist i have done this using the format as well
<%# DataBinder.Eval(Container.DataItem, "dProduct_price", "{0:n2}") %>'
now i have a datatable with a column called cost with datatype decimal.
cartDR["Cost"] = Decimal.Parse(lblProductPrice.Text);
But when i try to populate it i can the input string was not in a correct format. But it works ok if i remove {0:n2}
I'm not getting a trailing zero on currency values and I have no idea why not. This is my code:

Yet this is what is showing up on the screen:

Very aggrevating...It should not be doing this as I understand it.
If I want to display, say, 4 decimal points, what is the correct format?
View 3 RepliesWhen running our web application the following message appears:

i have a strange error creaping into my web app but am unsure as to how to fix it. When i run this code on my debug workstation it works fine but when i transfer it to my server things seam to go wrong.
dev station (windows 7) + VS2010
regional and language settings all set to uk
server (windows 2008r2)
regional and language settings all set to uk
What seams to be happening is that when converting a string to a double it works correctly on the dev environment but moves the decimal place to the end on the server.
example code(vb)
dim lat as string = "52.983829"
dim long as string = "-0.036500"
dim latint as double = lat
dim longint as double = long
now on the dev server the value of latint is 52.983829 as you might expect but on when published to the server it becomes 52983829.0 the same with longint on the dev staion it is -0.036500 but on the server it becomes -36500.0 i get equally confusing problems if i try to change it to an integer instead.
I have to validate for whether the string is decimal/numeric in code behind in asp.net.

I read a CSV file into a DataTable.The DataTable in the first image shows each column and type.The types are exactly what they are supposed to be and the data loaded all the rows it was supposed to load.From the second screen shot you can see the database table. SqlBulkCopy is supposed to map column names to database columns by default.According to that logic each column matches up exactly to the database and the column types also match.However,when I run the command it errors on the first row with:
"The given value of type String from the data source cannot be converted to type decimal of the specified target column."
Here is the StackTrace:

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).

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:
[Code]....
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?
Some values are returning 2.0 but I need it to be 2.00 as this is a money value that is displayed to the web page.
I am doing:
Math.Round(value, 2);
Is there a way to force it to 2 numbers after the decimal?
