第一种方法：
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
this.Label1.Text = GridView1.DataKeys[GridView1.SelectedIndex].Value.ToString();
}
第二种方法：
protected void TestGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
if(e.CommandName=="Increase")
{
//int index = Convert.ToInt32(e.CommandArgument);
//this.Label1.Text = GridView1.DataKeys[GridView1.SelectedIndex].Value.ToString();
this.Label1.Text = e.CommandArgument.ToString();
//GridViewRow row = GridView1.Rows[index];
Response.Write("<script language=javascript>alert('haahah')</script>");
}
