由 蓝咒 提交于 2021-01-28 00:51:51
问题 I have an object that contains eg a string property like "10; 20; 30". I have also a get property that splits the string, converts each part to a double and sums them up. Thus I have "10; 20; 30" and 60.0 (as double). Now the question is. Is there a way to display the 60.0 (as double) in a TextColumn, but when going to edit mode editing the string "10; 20; 30"? So that I can bind to one property for displaying and to bind to another property for editing? 回答1: You can achieve this with your

WPF DataGridTextColumn binding doesn't accept decimals

Why would it stop me from typing that character and how do I tell it to let me do so. I tried doing a string format like this: <DataGridTextColumn Header="Price" Binding="{Binding Price, Mode=TwoWay, UpdateSourceTrigger
