如何改变GridView最后一行的颜色

本文关键字：一行 颜色 GridView 何改变 改变 最后 | 更新日期: 2023-09-27 18:04:47

我在ASP中创建了一个网页。NET和c#。我取了一个GridView。我想改变或突出显示GridView最后一行的颜色。

请参考以下代码:-

protected void Page_Load(object sender, EventArgs e)
{
    DataSet ds = new DataSet();
    OracleConnection con = new OracleConnection("Data Source=10.31.41.103/ORCL;User ID=RL_PET;Password=RL_PET;Unicode=True");
    con.Open();
    OracleDataAdapter a = new OracleDataAdapter("SELECT NVL(MERGE,'GRAND_TOTAL') AS MERGE, COUNT(PALLET_NO) AS Total_Pallets , SUM(NET_WT) AS Net_Weight , SUM(GROSS_WT) AS Gross_Weight FROM WI_PALLET WHERE DATA_STS IN (2,3) AND TRANS_TYPE = 'P' GROUP BY ROLLUP (MERGE)", con);
    a.Fill(ds);
    GridView1.DataSource = ds;
    GridView1.DataBind();
    GridView1.Visible = true;
    con.Close();
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {

     }   
}

如何改变GridView最后一行的颜色

是的，使用GridView1.Rows[GridView1.Rows.Count - 1]，您将获得gridview的最后一行，正如已经在@Soner Gönül回答中提到的。

但不是使用RowDataBound事件，你需要使用PreRender，这里我添加了一个类，通过CSS你可以做更多的样式的东西。

你也可以使用BackColor属性和设置任何十六进制颜色代码，并使其突出显示

代码: 

  protected void GridView1_PreRender(object sender, EventArgs e)
    {
        GridViewRow getRow = GridView1.Rows[GridView1.Rows.Count - 1];
        getRow.Attributes.Add("class", "highlighted");
        // or
         getRow.BackColor = System.Drawing.Color.FromName("#EE0000");
    }

CSS:添加!重要的你可以覆盖默认的样式

 .highlighted td
  {
     color:Red ! important;
     background-color: blue ! important;
  }

使用CSS:

tr:last-child { color: red; }


tr:last-child { color:red; }
<table>
  <tr>
    <td>Head1</td>
        <td>Head2</td>
        <td>Head3</td>
    </tr>
  <tr>
    <td>Col1</td>
        <td>Col1</td>
        <td>Col1</td>
    </tr>
    <tr>
    <td>Col1</td>
        <td>Col1</td>
        <td>Col1</td>
    </tr>
    <tr>
    <td>Col1</td>
        <td>Col1</td>
        <td>Col1</td>
    </tr>
    <tr>
    <td>Col1</td>
        <td>Col1</td>
        <td>Col1</td>
    </tr>
  </table>

你可以找到你的最后一行使用它的Rows属性

gridView1.Rows[gridView1.Rows.Count - 1]

，你可以设置BackColor, ForeColor或BorderColor属性为;

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        gridView1.Rows[gridView1.Rows.Count - 1].BackColor = Color.Yellow;
        // Or you can set which color you want in Color enumeration.
    }   
}
