I am not sure of the answer, I have created a field in the Database and created a gridview.To show the .9393939393 a couple of decimal in the gridview. I used this format
.ToString("$#.################");
Through out the experiment, I found out that the decimal and the numeric are getting same format, is that right.

it displays on the page as 4.9 in a label control, it is previously calculated in the Calculate_Ratings(), and it is declared as a decimal, I have also tried it declared as double. My column is declared decimal(1,1) in sqlDatabase
The Error says

I currently have a numeric field as numeric(5,2) which has 2 digits after the decimal. Now I need to be able to display 4 digits after the decimal. But if I change the field to (7,4) then it places 2 zeros after the last numbers. For example: 1.32 changes to 1.3200.
But some records will have exactly 4 numbers after the decimal such as : 2.4375.
My issue is I don't want all the data to have 4 numbers after the decimal. I don't think there is another data type that will allow this.

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:

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?
I need a validation regex for decimal. It should allow upto 5 digits after decimal.

1,123.013
21,123.01234
3,21,123.01234
How Can I do regex for 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've just encountered an interesting problem in a standard BoundField in a GridView. The field is for EmployeeCode, which is purely numeric, but stored in a character column in the database. The DataFormatString="{0:00000}" attribute on the BoundField doesn't work, as I assume that format is only for numeric values.
To work around this, I had to use a TemplateField, and bind the text value using the attribute Text='<%# PadNumericString(Eval("EmployeeCode").ToString(), 5) %>'. Is there no simpler way of doing this?

View 1 RepliesI have a 'City' TextBox on one of my web pages but people from many European countries sometimes prefix the city name with the postcode instead of putting it in my dedicated 'Postcode/ZIP' TextBox. I have therefore just added a new RegularExpressionValidator to this TextBox. Its purpose is to prevent the user from entering any numeric characters but allow everything else. After browsing for a suitable regex (I am not a regex expert), I found the following code that was claimed to do what I want.
ValidationExpression="^D$"
Unfortunately, the RegularExpressionValidator does not work as expected. Instead of just rejecting numeric characters it appears to reject everything! Where might I be going wrong?
