在将列设为可编辑模式之前，DataGridTextcolumn的绑定文本中的数据不会显示 [英] Data in a Binded Text of DataGridTextcolumn does not appear un till Making the Column in editable Mode

问题描述

伙计们
我有一个带有称为税款"的列的数据网格，当我在此列bu用户中键入任何内容时，我在此列上创建了一种样式来管理我的火灾事件(文本已更改)，我成功完成了此操作，但是现在当我在该列中键入时事件我想要的问题是，只有在列处于可编辑模式下时，我在列中键入的数据才会出现，否则数据消失了，我该如何解决该问题?
在高级感谢

推荐答案

您应将TextColumn绑定到codebehind/viewmodel中的属性.然后，在该财产的设置工中，您可以适当地增加税收.像这样的东西:-

You should bind your TextColumn to a property in the codebehind/viewmodel. Then in the setter for that property you can increase the taxes appropriately. Something like this :-

<datagridtextcolumn binding="{Binding" path="Tax}/"></datagridtextcolumn>

并在您后面的代码中

and in your code behind

decimal tax;
decimal totalTaxes;
public decimal Tax
        {
            get { return tax; }
            set
            {
                if (tax == value) return;
                tax = value;
                totalTaxes += value;
                OnPropertyChanged("Tax");
            }
}
