Question

当用户更改该单元格的文本或内容时，我想更改数据网格中单元格的颜色。

我正在使用WPF和C＃。

我有一个简单的数据网格：

<DataGrid x:Name="dataGrid1" Grid.RowSpan="2" Margin="5" ItemsSource="{Binding Source=Horreos}" KeyDown="dataGrid1_KeyDown" SelectedCellsChanged="dataGrid1_SelectedCellsChanged"> <DataGrid.Columns > </DataGrid.Columns> </DataGrid>

此事件：keydown和selectedcellschange是更改我的颜色单元格的测试。在.cs中，我尝试过更换电池......但我失败了。

我需要在内容更改时发布的事件

Answer 1

设置行为，最简单的方法是使用Blend。我在博客文章{... 3}}

上提供了一个针对数据网格的示例

解决：

 private void dataGrid1_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
    {
        DataGridCell gridCell = null;
        try
        {
            gridCell = GetCell(dataGrid1.SelectedCells[0]);
        }
        catch (Exception)
        {
        }
        if (gridCell != null)
            gridCell.Background = Brushes.Red;

    }
public  DataGridCell GetCell(DataGridCellInfo dataGridCellInfo)
    {
        if (!dataGridCellInfo.IsValid)
        {
            return null;
        }

        var cellContent = dataGridCellInfo.Column.GetCellContent(dataGridCellInfo.Item);
        if (cellContent != null)
        {
            return (DataGridCell)cellContent.Parent;
        }
        else
        {
            return null;
        }
    }

private void MyDataGrid_LoadingRow(object sender, DataGridRowEventArgs e)
    {
        DataGrid grid = sender as DataGrid;
        e.Row.MouseEnter += (s, args) => Row_MouseEnter(s, grid);
        e.Row.MouseLeave += (s, args) => Row_MouseLeave(s, grid);
    }

    void Row_MouseLeave(object sender, DataGrid grid)
    {
        DataGridRow row = sender as DataGridRow;
        grid.SelectedIndex = -1;
    }

    void Row_MouseEnter(object sender, DataGrid grid)
    {
        DataGridRow row = sender as DataGridRow;
        grid.SelectedIndex = row.GetIndex();

    }

当用户完成编辑时，单元格变为红色。

 <DataGrid x:Name="dataGrid1" Grid.RowSpan="2" SelectionUnit="CellOrRowHeader" 
                     Margin="5" ItemsSource="{Binding Source=Source}" LoadingRow="MyDataGrid_LoadingRow"  CellEditEnding="dataGrid1_CellEditEnding">
            <DataGrid.Columns>

文本更改时，WPF数据网格会更改颜色
