本来是想模仿C/S的样子完成单击一列直接触发事件，后来知道那样要用到AJAX，最后还是用了RadioButton这样实现起来相对简单，不过只能在要求不高是时候用。
使用这个先要在gridview 里放入RadioButton模板。然后激发它的checked事件然后在此事件里可以捕捉到点的那一列，要注意就是点完了要将RadioButton的checked设置为false，这样看不到刚点过的痕迹，不过也算凑合能是些头的任务.....
protected void OrdersGridView_ClickChanged(object sender, EventArgs e)
{
foreach (GridViewRow row in this.OrdersGridView.Rows)
{
RadioButton radioButton = (RadioButton)row.FindControl("RadioButton1");
if (radioButton.Checked)
{
//显示从表内容
int i = Convert.ToInt32(radioButton.Text);
string sqlstr = "SELECT * FROM [Order Details] where orderID='" + i + "' ORDER BY [OrderID]";
string TableName = "OrderDetails";
GridViewBind(sqlstr, TableName, OrderDetailsGridView);
radioButton.Checked = false;
}
}
/// <summary>
/// 根据tablename和sql语句绑定GridView1到数据库
/// </summary>
/// <param name="sqlstr"></param>
/// <param name="tablename"></param>
/// <param name="GridView1"></param>
protected void GridViewBind(string sqlstr, string tablename,GridView GridView1)
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString);
SqlDataAdapter da = new SqlDataAdapter(sqlstr, con);
DataSet ds = new DataSet();
da.Fill(ds, tablename);
GridView1.DataSource = ds.Tables[tablename].DefaultView;
GridView1.DataBind();
}
下面的代码用脚本实现RadioButton的单选。不过当激活了RadioButton服务器端的checked事件后脚本事件作用被覆盖。
.aspx
// var last = null;//最后访问的RadioButton的ID
// function judge(obj)
// {
// if(last == null)
// {
// last = obj.id;
// // alert(last);
// }
// else
// {
// var lo = document.getElementById(last);
// lo.checked = false;
// //alert(last + " " + lo.checked);
// last = obj.name;
// }
// obj.checked = "checked";
// // alert(obj.id-100);
// }
.cs
protected void OrdersGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
RadioButton rb = (RadioButton)e.Row.FindControl("RadioButton1");
rb.Attributes.Add("onclick", "judge(this)");//给RadioButton添加onclick属
}
}
