推荐答案

见的 DataGridView.CellFormatting 事件。

此事件被称为时，它的时间格式的单元格。一个比较有用的东西，你可以在这个活动做的是改变基于单元格的值的单元格的内容和外观。

This event is called when it's time to format a cell. One of the more useful things you can do in this event is change the content and appearance of a cell based on the cell's value.

您将要学习code中的文档中，但我下面的一个片断显示了一点点，你可以做。所述CellFormatting事件下列检查，如果它的格式化在一个叫做Column3列中的单元格，如果它是与该单元格的值是0（字符串），它改变了细胞的值设定为假，细胞的背景色为红色。

You'll want to study the code in the documentation but I have a snippet below that shows a little you can do. The CellFormatting event below checks if it's formatting a cell in a column called "Column3" and if it is and the cell's value is 0 (as a string) ,it changes the cell's value to "False" and the cell's BackColor to red.

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e) {
    if (dataGridView1.Columns[e.ColumnIndex].Name == "Column3") {
        if (e.Value.ToString() == "0") {
            e.CellStyle.BackColor = Color.Red;
            e.Value = "False";
        }
    }
}
