Question

我有一个遍历gridview的循环，并计算性别字段设置为＆＃39; M＆＃39;单击按钮时。我也想用相同的条件改变那一行的那种颜色，即如果性别是＆＃39; M＆＃39;。

到目前为止，这是我的循环，非常感谢任何帮助！

protected void Button2_Click(object sender, EventArgs e)
{
    int intfemdelegates = 0;

    foreach(GridViewRow oItem in GridView1.Rows) 
    {
        if (oItem.Cells[6].Text.Contains('F'))
        {
            intfemdelegates = intfemdelegates + 1;
            GridView1.RowStyle.BackColor = System.Drawing.Color.Red;
        }
        Label2.Text = Convert.ToString(intfemdelegates);
    }
}

Answer 1

此代码可能有用......祝你好运！

int intfemdelegates = 0;
for (int i = 0; i < dataGridView1.Rows.Count-1; i++)
{
    if (dataGridView1[1, i].Value.ToString() == "F")
    {
        intfemdelegates = intfemdelegates + 1;
        dataGridView1[1, i].Style.BackColor = Color.Red;
        dataGridView1.Rows[i].DefaultCellStyle.BackColor = Color.Gray;
    }
}
lblcount.Text = intfemdelegates.ToString();

您正在整个Grid1上更改RowColor。改为这个

protected void Button2_Click(object sender, EventArgs e)  {
  int intfemdelegates = 0;

    foreach(GridViewRow oItem in GridView1.Rows) {
     if (oItem.Cells[6].Text.Contains('F')) {
       intfemdelegates = intfemdelegates + 1;
       oItem.BackColor = System.Drawing.Color.Red;
 }

   Label2.Text = Convert.ToString(intfemdelegates);

  }

在按钮点击功能中按条件更改gridview行颜色
