在gridview单元格中更改特殊单词的前景色

Question

我想改变一些特殊词而不是gridview单元格中所有词的颜色。 代码如下：

protected void gvContents_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (e.Row.Cells[3].Text.Contains("Special"))
        {
            //set The "Special" word only forecolor to red
        }
        else if (e.Row.Cells[3].Text == "Perishable")
        {
            //set The "Perishable" word only forecolor to blue
        }
        else if (e.Row.Cells[3].Text == "Danger")
        {
            //set The "Danger" word only forecolor to yellow
        }
    }
}

单元格文本可能如下所示：Radioactive : Danger 或此：Human Body : Special ,Perishable。我该怎么办？

Answer 1

结合使用 span tags 和 CSS 类。首先在您的 aspx 代码中创建 CSS 类：

<style>
    .redWord
    {
        color: Red;
    }
    .blueWord
    {
        color: Blue;
    }
    .yellowWord
    {
        color: Yellow;
    }
</style>

然后将所有出现的Special 替换为<span class='redWord'>Special</span>，将Perishable 替换为<span class='blueWord'>Perishable</span>，并将Danger 替换为<span class='yellowWord'>Danger</span>：

protected void gvContents_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Cells[3].Text = e.Row.Cells[3].Text.Replace("Special", "<span class='redWord'>Special</span>")
                              .Replace("Perishable", "<span class='blueWord'>Perishable</span>")
                              .Replace("Danger", "<span class='yellowWord'>Danger</span>");
    }
}

在 CellFormatting 事件处理程序中，添加以下代码

void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
    {
        if (e.Value != null && e.Value.ToString() == "Special")
        {
            e.CellStyle.ForeColor = Color.Red;
        }
    }
