C＃实体框架-十进制错误

Question

Trying to execute this code:

process.POPManagerPreparation.JudgementPercentage = (decimal?)txtAlternativePercentage.Value;

That works fine, but when the code Context.Current.SaveChanges(); is executed to save it in the database this ArgumentException occurs:

An error occurred while updating the entries. See the inner exception for details.
System.ArgumentException: Parameter value '3,0000' is out of range.

It's definitely about the field i've added, I know because of the value. (it changes when I check with other input)

I tried to change my computer settings from NL-nl to US-en, because it feels like there is something wrong with that but didn't solve it, the same error still exist.

Also tried some things on the text field, same error still:

    <telerik:RadNumericTextBox MinValue="0" MaxLength="100" ID="txtAlternativePercentage"
     runat="server" Type="Percent" Culture="en-US" Width="80px" LabelCssClass=""
     Label="Verhogingspercentage:" LabelWidth="130" AutoPostBack="true"
     OnTextChanged="SalaryChanged" Visible="false">
             <NumberFormat DecimalDigits="1" />
             <IncrementSettings InterceptArrowKeys="False" InterceptMouseWheel="False" />
    </telerik:RadNumericTextBox>

To be complete, the database field is: decimal(10, 5) so that's seems to be alright too. Found online a lot of issues with people that used too small fields but nothing on my issue.

Answer 1

You can specify the precision of your properties in your modelBuilder:

modelBuilder.Entity<POPManagerPreparation>()
            .Property(e => e.JudgementPercentage)
            .HasPrecision(10,5);

Answer 2

I solved it by changing to a float field like Pankaj Gupta suggested. This works fine.

so I've learned to not use a decimal unless you are sure that the value is strict about the decimal form it expects.
