WPF的关于控件的只能输入数字的控件C1NumericBox

<c1:C1NumericBox Width="80" Style="{StaticResource StackPanel-C1MaskedTextBox-Multiple}" AllowNull="False" Minimum="0" Format="N2" Value="{Binding Item.DK,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />

可以设置最小值和最大值，可以设置小数点位数N2就是2位小数点，另外样式由两种方式

<c1:C1NumericBox Width="80" Style="{StaticResource StackPanel-C1NumericBox-Multiple}" AllowNull="False" Minimum="0" Format="N2" Value="{Binding Item.DK,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />

列表中的小数位的字段显示也可以是使用Format="N2"，这样就保留2位小数了

也可以写触发事件ValueChanged="MaterialIncreaseCost_ValueChanged",这样多字段直接可以相互读取和赋值

<c1:C1NumericBox Width="90" Style="{StaticResource StackPanel-C1NumericBox-Multiple}" AllowNull="True" Format="N2" Value="{Binding CurrentParamReviewItem.ProcessIncreaseCost,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Name="ProcessIncreaseCost" ValueChanged="MaterialIncreaseCost_ValueChanged" />

private void MaterialIncreaseCost_ValueChanged(object sender, C1.WPF.PropertyChangedEventArgs<double> e)

{

double? materialIncreaseCost = MaterialIncreaseCost.Value;

double? processIncreaseCost = ProcessIncreaseCost.Value;

if (!materialIncreaseCost.HasValue)

{

materialIncreaseCost = 0;

}

if (!processIncreaseCost.HasValue)

{

processIncreaseCost = 0;

}

double sum = materialIncreaseCost.Value + processIncreaseCost.Value;

double roundedSum = Math.Round(sum, 2, MidpointRounding.AwayFromZero);

// 现在你可以使用roundedSum变量了，比如更新UI或进行其他计算

// 例如，更新另一个控件的Text属性来显示结果

//TotalCost.Text = roundedSum.ToString("N2");

TotalCost.Value = roundedSum;

}
