Question

我试图在点击它或点击按钮时获取特定网格视图行中的值。问题是当我点击该行时没有任何反应，甚至当我点击按钮时也没有。行是不可点击的。任何帮助

这是我的ASPx页面代码。

       <%@ Page Language="C#"Inherits="System.Web.Mvc.ViewPage<MvcApplication3.Models.Order>" %>

  protected void Page_Load(object sender, EventArgs e)
 {
    GridView1.DataSource = ViewData["list"];
    GridView1.DataBind();
 }

 protected void Button1_Click(object sender, EventArgs e)
 {


    CheckBox x;
    foreach (DataGridItem di in GridView1.Rows)
    {
        x = (CheckBox)di.FindControl("checkBox1");
        if (x.Checked == true)
        {
            Label5.Text = GridView1.SelectedRow.Cells[2].Text;
        }
    }
 }

 protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
 {
    Label5.Text = string.Format("YOu selected row{0} with {1} {2}",
                               GridView1.SelectedIndex + 1,
                               GridView1.SelectedRow.Cells[0].Text,
                               GridView1.SelectedRow.Cells[1].Text);
}

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
 {
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Attributes.Add("ondblclick", "__doPostBack('GridView1','Select$" +      e.Row.RowIndex + "');");
     } 
 }
</script>

丽娜，

虽然我没有解决您的问题，但我发现了数据一致性问题。

当您滚动复选框时，每次都会对Label5.Text进行改编。因此滚动是没有意义的，因为Label5只会显示它找到的最后一个Checkbox的值。

我可以建议以下替代方案：

    CheckBox x;
        foreach (DataGridItem di in GridView1.Rows)
        {
            x = (CheckBox)di.FindControl("checkBox1");
            if (x.Checked == true)
            {
                if(Label5.Text == "")
                {Label5.Text = GridView1.SelectedRow.Cells[2].Text;} 
                else {Label5.Text = Label5.Text + " - " +  GridView1.SelectedRow.Cells[2].Text;}
            }
        }

如果选择了1个复选框，则至少会将数据附加到字符串中并用“ - ”分隔。您可以根据需要随意更改分隔符。
