如何阻止DataGrid行颜色的变化？ [英] How to stop DataGrid row color from changing?

问题描述

在WPF DataGrid中选择一行时，我已经实现了代码来解决双击问题。我正在使用以下代码： http://stackoverflow.com/a/5857908/40106 。

I've implemented code to get around the double click issue when selecting a row in a WPF DataGrid. I'm using the following code from here: http://stackoverflow.com/a/5857908/40106.

<Style TargetType="DataGridCell">
     <Style.Triggers>
         <Trigger Property="IsMouseOver" Value="True">
             <Setter Property="IsEditing" Value="True" />
         </Trigger>
     </Style.Triggers>
 </Style>

行有交替的颜色。问题是当我将鼠标悬停在一列，在一列中，浅蓝色被白色代替。

Rows have alternating colors. The problem is when I mouse over a row, in one column, the light blue color is replaced by white.

除了这个问题以外，上述代码非常有用。

The above code works great except for this one issue. How do I stop the color from changing when mousing over a row?

我尝试过以下操作，但没有任何影响：

I have tried the following but it doesn't have any effect:

<Style TargetType="DataGridCell">
     <Style.Triggers>
         <Trigger Property="IsMouseOver" Value="True">
             <Setter Property="IsEditing" Value="True" />
             <Setter Property="Background" Value"AliceBlue" />
         </Trigger>
     </Style.Triggers>
 </Style>

推荐答案

问题是，单元格将显示它的编辑

The problem is, that the cell will display it's edit style when you hover the mouse above the cell.

对于 DataGridTextColumn 这意味着，一个 TextBox 显示白色背景。

For a DataGridTextColumn this means, that a TextBox with a white background is displayed.

您可以将样式设置为< DataGridTextColumn.EditingElementStyle> 并将背景设置为透明。

You can set a Style to <DataGridTextColumn.EditingElementStyle> and set the Background to transparent.

<DataGridTextColumn Header="Name" Binding="{Binding Name}" >
    <DataGridTextColumn.EditingElementStyle>
        <Style TargetType="TextBox">
            <Setter Property="Background" Value="Transparent"></Setter>
            <Setter Property="BorderThickness" Value="0"></Setter>
        </Style>
    </DataGridTextColumn.EditingElementStyle>
</DataGridTextColumn>

<

To get the white Background, when actually editing the cell you could add another trigger to the IsSelected event:

<Style TargetType="DataGridCell">
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="IsEditing" Value="True" />
        </Trigger>

        <Trigger Property="IsSelected" Value="True">
            <Setter Property="Background" Value="White"/>
        </Trigger>

    </Style.Triggers>
</Style>

另一个选择是将DataGridCell样式应用于仅限CheckBoxColumns。对于其他列类型，它不会有什么不同。

Another option would be to apply the DataGridCell Style to CheckBoxColumns only. For other Column types it wouldn't make a difference anyway.
