用图像替换DataGridView单词和数字

我们将资源文件中的图像存储为BMP文件。然后,我们在DataGridView中处理CellFormatting事件,如下所示:

    private void messageInfoDataGridView_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
    {
        // Is this the correct column? (It's actually a DataGridViewImageColumn)
        if (messageInfoDataGridView.Columns[e.ColumnIndex] == messageSeverityDataGridViewTextBoxColumn)
        {
            // Get the row we're formatting
            DataGridViewRow row = messageInfoDataGridView.Rows[e.RowIndex];
            // Get the enum from the row.
            MessageSeverity severity = ((MessageInfo)row.DataBoundItem).MessageSeverity;
            Bitmap cellValueImage;
            // Map the enumerated type to an image...
            // SeverityImageMap is a Dictionary<MessageSeverity,Bitmap>.
            if (ReferenceTables.SeverityImageMap.ContainsKey(severity))
                cellValueImage = ReferenceTables.SeverityImageMap[severity];
            else
                cellValueImage = Resources.NoAction;

            // Set the event args.
            e.Value = cellValueImage;
            e.FormattingApplied = true;
        }
    }

网格视图可以使用图像字段,而不是数据绑定字段。这听起来像是在耍花招。
