我如何编程的方法修改DataGrid行的颜色在WPF？ [英] How do I programatically change datagrid row color in WPF?

问题描述

我如果可能的疑惑。我有这个数据网格包含3列和2行。 。我要的是根据我输入的数据更改URL栏的背景在我的DataGrid

I was wondering if this possible. I have this datagrid contains 3 columns and 2 rows. What I want is to change the background of the URL column on my datagrid according to the data I enter.

下面是我的XAML代码示例：

Here is sample of my xaml code:

<DataGrid
    x:Name="mylistview"
    BorderBrush="#FF373737"
    Background="Black"
    VerticalGridLinesBrush="#FF232323"
    HorizontalGridLinesBrush="#FF212121">
    <DataGrid.Columns>
        <DataGridTextColumn Header="URL" Foreground="{Binding rowColor}" Binding="{Binding url}"/>
        <DataGridTextColumn Header="Version" Foreground="White" Binding="{Binding version}"/>
        <DataGridTextColumn Header="Valid" Foreground="White" Binding="{Binding valid}"/>
    </DataGrid.Columns>
</DataGrid>

我的阶级用来填补与行的数据网格：

My class used to fill up the datagrid with rows:

public class myData
{
    public string url {get; set;}
    public string version{get; set;}
    public string valid{get; set;}

    //this should be the value that changes the bg color 
    public string rowColor{ get; set; }
}

这是我的方式行添加到控制：

And here is my way to add rows to the control:

 myData data1 = new myData();
 data1.url = "http://google.com";
 data1.valid = "yes";
 data1.version = "1";
 data1.rowColor = "#FF000000";
 this.mylistview.Items.Add(data1);

 data1.url = "http://yahoo.com";
 data1.valid = "no";
 data1.version = "1";
 data1.rowColor = "#000000FF";
 this.mylistview.Items.Add(data1);

我有两个元素。每行应该有自己的颜色。第一个应该是红色
和第二个应该是蓝色的。我真的不知道如何控制使用rowColor值。

I have two elements. Each row should have its own color. The first one should be red and the second one should be blue. I really don't know how to make the control use the rowColor value.

什么我需要做的就是这个工作？

What do I need to do to get this working?

推荐答案

您 rowColor 不应该返回一个字符串（我将其重命名为 rowColor ，因为它是公开的），刚刚返回的实际颜色的画笔来代替。 （你的颜色是错的方式，首先是不透明的黑色，第二个是透明的蓝色）

Your rowColor should not return a string (i would rename it to RowColor since it is public), just return the actual colour-brushes instead. (Your colours are wrong by the way, the first is opaque black and the second is transparent blue)

例如

public Brush rowColor { get; set; }

data1.rowColor = Brushes.Red;
data2.rowColor = Brushes.Blue;

如果你真的需要从字符串进行解析时，你可以使用的值转换器或所使用的标准转换分析的XAML的时候。

If you really need to parse from string you could use a value converter or the standard conversion that is used when parsing Xaml.

除此之外我不知道如果这些特性结合前景的列会工作。

Besides that i am not sure if binding those properties to Foreground of the column will work.
