WPF Datagrid单元格中“突出显示文本”的背景颜色

Question

This is not the simple "IsSelected" background color of a datagrid row. What I am referring to is when I am in a datagrid, that has editable data, I click in a given cell and have any text (for example an address), if I select part of the text, the HIGHLIGHT coloring is what I want to change... I assume it would be part of the DataGridCell styling, but not sure where.

Answer 1

You are looking for the TextBoxBase.SelectionBrush Property . From the linked page on MSDN:

Gets or sets the brush that highlights selected text.

<TextBox SelectionBrush="Red" SelectionOpacity="0.5" 
    Foreground="Blue" CaretBrush="Blue">  
    This is some text.
</TextBox>

UPDATE >>>

You can apply this property in a Style that is applied to the DataGridTextColumn.EditingElementStyle property, like this:

<DataGrid ItemsSource="{Binding Items}" AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTextColumn Binding="{Binding Name}">
            <DataGridTextColumn.EditingElementStyle>
                <Style TargetType="{x:Type TextBox}">
                    <Setter Property="SelectionBrush" Value="Red" />
                </Style>
            </DataGridTextColumn.EditingElementStyle>
        </DataGridTextColumn>
    </DataGrid.Columns>
</DataGrid>
