C# 如何在分页-GridView PagerTemplate中突出显示当前编号？

这是我当前在GridView中的设计，单元格在悬停时变成橙色，这是通过使用css实现的。但我的问题是，如果单元格背景颜色是活动的，我如何更改它

HTML代码：（仅GridView）

PopulateGridView

public void PopulateGridView()
{
    String constring = System.Configuration.ConfigurationManager.ConnectionStrings["sqlconnect"].ToString();
    MySqlConnection con = new MySqlConnection(constring);
    using (MySqlCommand cmd = new MySqlCommand("SELECT * FROM tabletester"))
    {
        cmd.CommandType = CommandType.Text;
        cmd.Connection = con;
        con.Open();
        MySqlDataReader reader = cmd.ExecuteReader();
        DataTable dt = new DataTable();
        dt.Load(reader);

        con.Close();

        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
}

您可以在

Repeater\u ItemDataBound

if (e.Item.ItemIndex == GridView1.PageIndex)
{
    lnkPageNumber.ForeColor = Color.Red;
}

也就是说，您现在知道GridView有内置的分页系统吗？比你正在做的过于复杂的事情容易得多。以下是所有代码：

ASPX

就是这样。功能性寻呼系统所需的所有代码。

我理解，但我必须包括“第一个”、“上一个”、“下一个”和“最后一个”按钮，这就是我选择此路线的原因。为了便于设计，我必须将页码包含到表格单元格中。然后看看我的答案，它显示了一些标准寻呼机选项以及如何自定义：。但我的第一个答案应该回答你的问题。
