DataList 控件具体用法 (下)

  

7．看到上面的事件了吗。下面要做的任务就是写这些事件

protected void DataList1_EditCommand(object source, DataListCommandEventArgs e)

    {

        DataList1.EditItemIndex = e.Item.ItemIndex;

        dataBindToDataList();

    }

    protected void DataList1_CancelCommand(object source, DataListCommandEventArgs e)

    {

        DataList1.EditItemIndex = -1;

        dataBindToDataList();

 

    }

    protected void DataList1_UpdateCommand(object source, DataListCommandEventArgs e)

    {

        string auid = Convert.ToString (DataList1.DataKeys[e.Item.ItemIndex]);

        string phone = ((TextBox)e.Item.FindControl("txtphone")).Text;

        SqlConnection con = data.Getcon();

        con.Open();

        SqlCommand cmd = new SqlCommand("update authors set phone='"+phone+"'where au_id='"+auid+ "' ",con);

        cmd.ExecuteNonQuery();

        DataList1.EditItemIndex = -1;

        dataBindToDataList();

    }

    protected void DataList1_DeleteCommand(object source, DataListCommandEventArgs e)

    {

        string auid = Convert.ToString(DataList1.DataKeys[e.Item.ItemIndex]);

 

        SqlConnection con = data.Getcon();

        con.Open();

        SqlCommand cmd = new SqlCommand("Delete from authors where au_id='" + auid + "' ", con);

        cmd.ExecuteNonQuery();

        DataList1.EditItemIndex = -1;

        dataBindToDataList();

    }

}

运行如图:
