I have 20 ratings and a textbox I think the error is with the last parameter @Overall

DataSource Controls :: Numeric Fields / Display 4 Digits After The Decimal?

Feb 23, 2010

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.

Format A Numeric String Using A Numeric Composite Format?

Aug 9, 2010

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?

When running our web application the following message appears:

The user_id should be the output after successful insert of record. The stored procedure works well from within the DB and Visual Studio. Our DB version: 11gR1 on Windows.The web form has a button event with this c#-code:
