如何使用WPF C＃和Ado.Net数据实体将十进制值插入货币数据类型列

Question

I'm trying to save prices for products from a textbox. I know I have to convert or parse the input into decimal datatype. Now I have two question about this:

1. How to make the output format (when it shows the price in the datagrid) fit my need, to show only two digits after the "," or "."?
2. what's the best way to set the price with cents? to make 2 textboxes and concat them somehow or set it manually from just 1 textbox? if the second case, how to make the textbox only allow numbers with "," or "." and just 2 digits after the comma or point?

Hope my questions are clear!

Answer 1

It sounds like you need a style for your TextBoxes. Here's a basic style that should provide you with enough information to research the terms included so you can alter it to act how you want. You may need to bind a Path.

<Style x:Key="MoneyStyle" TargetType="{x:Type TextBox}">
    <Setter Property="Text" Value="{Binding StringFormat='###,###.##'"/>
</Style>
