如何在ASP.Net中编辑gridview中的行

亲爱的朋友们，

我有gridview，它包含文本框，我将数据绑定到该文本框现在我想要更改文本框数据并传输到DB，我会在GridViewRowCommand事件，但是有一些问题，所以即时尝试在GriViewRowUpdating事件中，但即使是在编辑按钮点击事件中也不会激活...请帮帮我????

//这个我的代码



public void GridView1_RowUpdating（object sender，GridViewUpdateEventArgs e）

{



string CheckpointName =（（TextBox）GridView1.Rows [e.RowIndex]

.FindControl（somevalue））。Text;

string Query =UPDATE check_points SET CHECKPOINT_NAME ='+ CheckpointName +'WHERE ROOT_ID ='+ TextBox1.Text +';

if（access.insert_delete_update（Query））

{

ScriptManager.RegisterStartupScript（this，this.GetType（），

" Message"，" alert（Error）;"，true）;

}

GridView1.EditIndex = -1;

GridView1.DataBind（）;



}
